Revision of the Southeast Asian millipede genus Orthomorpha Bollman, 1893, with the proposal of a new genus (Diplopoda, Polydesmida, Paradoxosomatidae)

The large genus Orthomorpha is rediagnosed and is shown to currently comprise 51 identifiable species ranging from northern Myanmar and Thailand in the Northwest to Lombok Island, Indonesia in the Southeast. Of them, 20 species have been revised and/or abundantly illustrated, based on a restudy of mostly type material; further 12 species are described as new: Orthomorpha atypica sp. n., Orthomorpha communis sp. n., Orthomorpha isarankurai sp. n., Orthomorpha picturata sp. n., Orthomorpha similanensis sp. n., Orthomorpha suberecta sp. n., Orthomorpha tuberculifera sp. n.,Orthomorpha subtuberculifera sp. n. and Orthomorpha latiterga sp. n., all from Thailand, as well as Orthomorpha elevata sp. n.,Orthomorpha spiniformis sp. n. and Orthomorpha subelevata sp. n., from northern Malaysia. The type-species Orthomorpha beaumontii (Le Guillou, 1841) is redescribed in due detail from male material as well, actually being a senior subjective synonym of Orthomorpha spinala (Attems, 1932), syn. n. Two additional new synonymies are proposed: Orthomorpha rotundicollis (Attems, 1937) = Orthomorpha tuberculata (Attems, 1937), syn. n., and Orthomorpha butteli Carl, 1922 = Orthomorpha consocius Chamberlin, 1945, syn. n., the valid names to the left. All species have been keyed and all new and some especially widespread species have been mapped. Further six species, including two revised from type material, are still to be considered dubious, mostly because their paraterga appear to be too narrow to represent Orthomorpha species. A new genus, Orthomorphoides gen. n., diagnosed versus Orthomorpha through only moderately well developed paraterga, coupled with a poorly bi- or trifid gonopod tip, with at least some of its apical prongs being short spines, is erected for two species: Orthomorpha setosus (Attems, 1937), the type-species, which is also revised from type material, and Orthomorpha exaratus (Attems, 1953), both comb. n. ex Orthomorpha.

Histoires de la Terre: Earth Sciences and French Culture, 1740–1940 ed. by Louise Lyle, David McCallam

clairement que le burlesque n’est pas “un épiphénomène marginal” (326) du dixsepti ème siècle littéraire mais qu’il possède les caractéristiques des mouvements de pensée de l’époque. À travers l’exposition des incongruités des œuvres antiques, les auteurs du burlesque se rangent parmi ceux pour qui la poésie est le résultat d’un “travail assidu” (290) et non d’une inspiration divine. Dans la parodie des œuvres antiques se retrouve aussi le courant rationnel et “moderne” qui offre un regard critique sur ces textes. Leclerc note justement “le rôle préliminaire” (324) du travestissement dans la Querelle des Anciens et des Modernes. Écrit dans une langue claire avec de multiples extraits d’œuvres burlesques, L’Antiquité travestie et la vogue burlesque en France offre un portrait approfondi et nuancé de ce mouvement littéraire, partie prenante du Grand Siècle. Hope College (MI) Brigitte Hamon-Porter LYLE, LOUISE, and DAVID MCCALLAM, eds. Histoires de la Terre: Earth Sciences and French Culture, 1740–1940. Amsterdam: Rodopi, 2008. ISBN 978-90-420-2477-9. Pp. 272. 54 a. These fifteen essays argue that geological ideas were more widespread and influential in French culture than we realize. Benoît de Baere finds that Buffon’s Histoire naturelle tries to reconcile the competing voices of the pioneering geologist , the philosophe contrasting the experience of natural catastrophe with the idea of the goodness of God, and the esthete marveling at the sublimity of earthquakes , volcanic eruptions, and tsunamis. Grégory Quenet claims that the Lisbon earthquake of 1755 impelled Europeans to understand natural catastrophes as historical events. 1755 to 1762 witnessed exceptional seismic activity in Europe. A growing realization that shock waves circulated through solid matter shifted their explanation from divine wrath to physics. Rebecca Ford studies the mineralogical plates of Diderot and d’Alembert’s Encyclopédie that enhanced scientific awareness of the Earth’s composition and history. Ian D. Rotherham and David McCallam discuss the strife between peasants and government authorities for rights to the marshlands, which were traditional commons. Greg Kerr reviews the influence of engineering and cartography on Saint-Simonian theories of social reorganization. Ceri Crossley reviews the midnineteenth -century socialist Pierre Leroux’s theories of a regenerative return to the soil through organic farming, recycling human wastes as fertilizer. Scott Sprenger gratuitously contrasts Freud’s notion of the individual unconscious unfavorably with Balzac’s social unconscious in Sarrasine. He associates the novelist’s frequent archeological metaphors with historical traumas in characters alienated from their past. But he repeatedly misinterprets the story’s psychological implications. Claire Le Guillou highlights George Sand’s passionate interest in archeology, a natural complement to her interest in folk traditions. She financed some digs and participated in others in 1853 and 1857. This hobby affected her later works; she wove Celtic remains into the plots of Jeanne and Nanon. Among authors, Jules Verne predominates. Tim Unwin emphasizes the pedagogical dimension of the Voyages extraordinaires in exploring remote and extreme environments while selfconsciously extending the frontiers of fiction. European imperialism and encyclopedic plagiarism mark his polyphonic, experimental novels. Anca Mitroi’s study Reviews 175 is an hors-sujet in this volume. Kiera Vaclavik’s well-documented treatment of the underground in children’s literature of the nineteenth century is grounded in the literature of Antiquity. Reading Alfred Jarry’s Gestes et opinions du docteur Faustroll, Ben Fisher enumerates allusions to Jarry’s literary circle, to British scientists, and to Verne. In the twentieth-century section, Louise Lyle studies J.-H. Rosny’s concept of the Earth as a text “in which mankind’s apocalyptic destiny may be read” (219) while it unfolds according to Darwin and Lamarck. Humans sink into apathy as superior species arise to exterminate them. Rosny thus anticipates both the ecocriticism and biocentric inhumanism of our day. David Walker illuminates Gide’s Nourritures terrestres and L’immoraliste in an outstanding essay that explains how Gide literally returned to the soil while those two works were composed, managing a farm inherited from his mother in 1895, with the advice of a long-time agriculturist friend. Martin Hurcombe concludes the volume with another fine...

The genus Conocephalus (Orthoptera, Tettigonioidea) in China

A revision of Conocephalus Thunberg and its relatives from China is reported. One new combination Conocephalus brevivalva (Shi et al., 2005), one new Chinese record Conocephalus oceanicus (Le Guillou, 1841) and one new species Conocephalus shanghaiensis sp. nov. are presented. The type specimens are deposited in the Shanghai Entomological Museum, CAS.

Estimate of the critical exponents from the field-theoretical renormalization group: mathematical meaning of the “Standard Values”

New estimates of the critical exponents have been obtained from the field-theoretical renormalization group using a new method for summing divergent series. The results almost coincide with the central values obtained by Le Guillou and Zinn-Justin (the so-called "standard values"), but have lower uncertainty. It has been shown that usual field-theoretical estimates implicitly imply the smoothness of the coefficient functions. The last assumption is open for discussion in view of the existence of the oscillating contribution to the coefficient functions. The appropriate interpretation of the last contribution is necessary both for the estimation of the systematic errors in the "standard values" and for a further increase in accuracy.

Journal intime inédit, volume VI (1854-1858) (review)

Reviewed by: Journal intime inédit, volume VI (1854-1858) Marc Serge Rivière Montalembert, Charles de. Journal intime inédit, volume VI (1854-1858). Eds. Louis Le Guillou and Nicole Roger-Taillade. Paris: Honoré Champion, 2006. Pp. 799. ISBN 978-2-7453-1358-4 Charles-Forbes-René, Comte de Montalembert, Catholic publicist, historian, politician and orator, was born in London on 15 April 1810 and died in Paris on 13 March 1870. A year spent as a student in Fulham (1820) allowed him to become proficient in English, and his mother, née Forbes, was from an old Aristocratic Scottish family, to which the Irish Earls of Granard belonged. Charles went on to study philosophy and rhetoric at Collège Sainte-Barbe in Paris (1826-27), before accompanying his father, Marc René, who had been appointed French Ambassador in Stockholm (1828). On his return to France in 1829, Montalembert studied Law (1829), but soon, the eager young traveller set out on a tour of Ireland in September and October 1830. This visit transformed him from a budding political thinker into the leading figure of the Catholic Liberal Movement in France and a brilliant orator on constitutional liberties and the union of Catholicism, Freedom and Democracy. In 1830, Montalembert joined Lamennais, whose death is reported in volume VI (33), in founding the Catholic liberal journal, L'Avenir. Montalembert published three letters therein (1-18 January 1831), which were later merged to form the Lettre sur le Catholicisme en Irlande (Œuvres polémiques [. . .], Paris: Lecoffre, 1860, vol. 1: 127-67). In a brilliant political career from 1830 onwards, he championed the cause of Irish, Polish, Greek and Swiss Catholics, both in the Legislative Assembly, to which he was elected as Deputy for Doubs (1848-57), and in the Académie française (1851-70). During the July Monarchy and the Second Empire, he became the leader of the Catholic militants, denouncing strongly Napoleon III's despotic regime in the 1850s as undermining morality and religion and decrying the French nation's voluntary subservience. Based on manuscripts found at the Archives of La Roche-en-Bresnil and at the Archives de la Côte d'Or (Dijon), the first six volumes of Montalembert's notebooks provide an invaluable tool to the far too few scholars, alas, who study his thought nowadays. Volume II (1830-33, Paris: CNRS, 1990) is an especially rich document on the philosopher's formative period in Sweden and Ireland. It also provides much insight into the rigorous documentation undertaken in the 1830s for an aborted History of Ireland. By contrast, in the admission of the editors, volume VI was less spontaneously written and was planned as part of a whole intended for publication, with more precise dating of events. The structure of various sections is compared by Roger-Taillade to a series of chapters or dramatic scenes of the author's life (introduction 7). Yet, sufficient insight can be gained into Montalembert's psyche, as a family man and a political figure, both sensitive to public opinion and frustrated by adverse criticism. He frequently bares his soul and reveals his intimate reactions to the hostility of the French clergy (605), the hypocrisy of his bête noire, Napoleon III (631), and the desertion of French literati. Above all, he makes no bones of his distress and loneliness during his trial of [End Page 362] 1858, following the publication of "Un débat sur l'Inde au Parlement anglais" in the Correspondant (25 October 1858; vol. XV, 205-73). The reader is fully aware of: the anxiety and stress that accompanied this public trial, "the most momentous day in [his] life" (621), a prosecution malevolently engineered by the Emperor, an "adventurer without a conscience" (631); Montalembert's admiration for his brilliant lawyers, Berryer and Dufaure (613); his unfair condemnation to six months' imprisonment and a fine of 3, 000 Francs (622); his despair at the silence of European liberal journals and at the indifference of the general public (628). He also voices his exhilaration upon his unexpected victory (643) in an appeal launched after he had rejected the Emperor's "perfidious" pardon (631). The detailed narrative of the 1858...

Life-history traits of a gastropod, Nerita squamulata Le Guillou 1841, on a subtropical cobbled shore disturbed by sand

Cobbled shores in subtropical Japan are small and disturbed by sand transported from terrestrial runoff. How benthic organisms live in such a harsh environment has been seldom studied. On a cobbled shore at Ishigaki Island, the present study investigated the life-history traits of the gastropod, Nerita squamulata Le Guillou 1841. Seasonal quadrat samplings showed that the neritid density decreased when and where sand covered cobbles, indicating impact of sand on the neritid. Monthly frequency histograms of the shell width suggested that the neritid lives less than 2 years and recruits as individuals of 1-4 mm shell width in both May-August and February. With the possible short longevity and frequent recruitments, the neritid population may quickly recover after the disturbance by sand.

Scaling Behavior and Structure of Denatured Proteins

An ensemble of random-coil conformations with no persistent structures has long been accepted as the classical model of denatured proteins due to its consistency with the experimentally determined scaling of protein sizes. However, recent NMR spectroscopy studies on proteins at high chemical denaturant concentrations suggest the presence of significant amounts of native-like structures, in contrast to the classical random-coil picture. To reconcile these seemingly controversial observations, we examine thermally denatured states of experimentally characterized proteins by using molecular dynamics simulations. For all studied proteins, we find that denatured states indeed have strong local conformational bias toward native states while a random-coil power law scaling of protein sizes is preserved. In addition, we explain why experimentally determined size of the protein creatine kinase does not follow general scaling. In simulations, we observe that this protein exhibits a stable intermediate state, the size of which is consistent with the reported experimental observation.

Sex differences in immunity in two species of field crickets

Immune defense often differs between the sexes, with males often having a weaker response, at least among many vertebrates. We examined encapsulation ability, a cell-mediated immune response, in laboratory and field populations of two species of field crickets, Teleogryllus oceanicus (Le Guillou, 1841) and Teleogryllus commodus (Walker, 1869), which have different life histories. In the seasonally breeding T. commodus, males show a stronger encapsulation response than females in both the laboratory and the field, although the difference is more marked under field conditions. The aseasonal T. oceanicus showed no sex difference in encapsulation in either field or laboratory samples fed ad libitum, but when food was experimentally reduced, the same pattern of stronger male response emerged. It is possible that this pattern may result from selection on females to increase investment in reproduction when time and energy for breeding are limited, as is more likely for seasonal breeders or animals under food restriction.

Sinantropia de los Calliphoridae (Diptera) de Valdívia, Chile

The objective of this study was to determine synathropic index of adult Calliphoridae (Diptera) collected in the city of Valdivia, Chile (39o48 S; 73o15 ' W). For this, samples were taken monthly between September 1996 and August 1997 in three different localities representing urban, rural and natural environments. Rat carcass, fish , and chicken viscera were used as baits. Four blowfly species were collected: Calliphora vicina Robineau-Desvoidy, the dominant species in all three baits and sites of capture, followed by Lucilia sericata (Meigen), both species being eusynanthropic. The other two species, Compsomyiops fulvicrura (Robineau-Desvoidy) and Sarconesia magellanica (Le Guillou), were collected in smaller numbers and were characterized respectively as hemysinanthropic and asynanthropic. In addition to the synanthropic index, the monthly abundance and the efficiency of the baits as attractans to the flies as well as their medical and sanitary importance were also determined and discussed.

Critical exponents of theN-vector model

Recently the series for two RG functions (corresponding to the anomalous dimensions of the fields phi and phi^2) of the 3D phi^4 field theory have been extended to next order (seven loops) by Murray and Nickel. We examine here the influence of these additional terms on the estimates of critical exponents of the N-vector model, using some new ideas in the context of the Borel summation techniques. The estimates have slightly changed, but remain within errors of the previous evaluation. Exponents like eta (related to the field anomalous dimension), which were poorly determined in the previous evaluation of Le Guillou--Zinn-Justin, have seen their apparent errors significantly decrease. More importantly, perhaps, summation errors are better determined. The change in exponents affects the recently determined ratios of amplitudes and we report the corresponding new values. Finally, because an error has been discovered in the last order of the published epsilon=4-d expansions (order epsilon^5), we have also reanalyzed the determination of exponents from the epsilon-expansion. The conclusion is that the general agreement between epsilon-expansion and 3D series has improved with respect to Le Guillou--Zinn-Justin.

Seasonal fluctuations in bodyweight, lipid content and the starvation‐longevity ofAmorbus obscuricornis(Westwood) andGelonus tasmanicus(Le Guillou) (Hemiptera: Coreidae)

The live weight (LW) and dry weight (DW), lipid and water content and starvation‐longevity of adultAmorbusobscuricornisand adultGelonustasmanicuswere examined in successive seasons.Amorbusobscuricorniswas consistently heavier thanG.tasmanicus. In both species, water content was inversely related to lipid content. The LW, DW and lipid contents ofA.obscuricorniswere lowest in spring. In contrast, LW and DW ofG.tasmanicuswere highest in spring, whereas lipid content was highest in autumn. These differences appear to be related to the reproductive cycles of these species. Starvation‐longevity of both species was affected by relative humidity, being greatest at 99% and declining rapidly below 80%, and by temperature, being greatest forA.obscuricornisat 10.6°C and increasing forG.tasmanicuswith decreasing temperature to 4.5°C. These differences may be related to differences in the habitat preferences of the two species, withG.tasmanicusapparently preferring cooler habitats thanA.obscuricornis. It was considered that the conditions that pre‐wintering adults of either species could withstand would facilitate their hibernation.

An introduction to Old Russian By William Schmalstieg (review)

LANGUAGE, VOLUME 73, NUMBER 4 (1997) nicht unbeträchtlich verändert.' For the historical record it would have been interesting to include in an appendix S's chapter from the second edition on 'Prinzipien', namely, his approach to methodology; particularly interesting here is his analysis ofthe relationship of his work to Darwinism. Kuhn's 90-page review emends many of S's forms. [Lisi Oliver, Louisiana State University.] An introduction to Old Russian. By William Schmalstieg. (Journal of Indo-European Studies. Monograph 15.). Washington, DC: Institute for the Study of Man, 1995. Pp. 311. Old Russian is the sum of all Eastern Slavic tribal and later territorial dialects that modern Eastern Slavic languages have developed from. Old Russian was spoken in the Kievan Rus' between the eighth and fifteenth centuries. This linguistic system is the standard that the development and history of Eastern Slavic languages are measured against. The first and so far the most detailed description of the phonetic structure and the dialects of Old Russian is the work of A. A. Schmatov (Ocerk drevnejsego penoda istorii russkogo jazyka. Enciklopedija slavjanskoj filologii. 11/1 Petrograd, 1915). In the former Soviet Union a number of Old Russian grammars were published especially for students of history . So far the only Old Russian grammar by a foreigner that we know of is Jean-Yves Le Guillou's Grammaire de vieux russe (Études Linguistiques XII. Paris, 1972). Schmalsteig's book, as far as we know, is the first Old Russian grammar in English by the well-known Indo-Europeanist and Slavist. The 'Foreword' and 'Abbreviations' are followed by six chapters: 'The Cyrillic alphabet' (13-15), 'Brief remarks in phonology' (16-49), "The adjective , pronoun & numeral' (50-75), "The noun' (76-88), 'The verb' (89-145), and ? few remarks on syntax' (146-75). These are followed by 'Reading selections' (176-91) and 'Vocabulary' (192-302). The book concludes with a well selected 'References and brief bibliography' (303-11). The book contains all one needs to know about Old Russian and can be used to teach that language. As to the arrangement of the material, instead of taking the traditional approach, S begins discussing morphology with 'The adjective, pronoun & numeral ' , probably out of pedagogical considerations. The short, well summarized, and to the point syntax is a special merit of this book. Two missing aspects should be mentioned here (1) It is regrettable that the book omits to mention the linguistic records of Old Russian. (2) Although the author occasionally refers to Old Russian dialectal phenomena (19, 22, 30, 31, 40, etc.), this information remains fragmented. It would have been desirable to sum up the dialects of Old Russian in a separate chapter. Concerning the material discussed by S, the following should be emphasized: (1 ) In some cases there are earlier data than that referred to by S on the phenomena . (2) Certain changes are mentioned without examples or data. Linguistic records can be useful sources here (e.g. -ce, -zë, -se > -kë, -gë, -chë). (3) Some of his examples are not convincing; in the case ofpotreubBno, posreudu (35) the letter e in the place of the yat is not the reflection of the ë > e change, but of Church Slavonic pronunciation. The development of the Old Russian personal pronoun jejê (gen sing, fern.) > jeje > jejo rules out a phonetic explanation for the gen. sing, nom., ace. plur. fern., ace. plur mase, -ja morpheme of binary types. These forms can probably be regarded as hybrid Old Slavic-Old Russian forms. Although not based on independent research, S's book is founded on the best monographs and articles and is informed by a consistent scientific approach. The author has a feeling for pedagogy, and he has produced an interesting book, complemented with a number of original observations. A special merit of the book is that instead of describing Old Russian phenomena only (40, 41, 81, 82, etc.), S refers to modern Russian as well. Thus behind the modest title of his book we have a well written, excellent Russian historical grammar. It is a pity that this useful book meant for everyday use has been bound in a shamefully poor fashion. [Imre H. Tóth. JózsefAttila University...

Comparison of damage to Eucalyptus caused by Amorbus obscuricornis and Gelonus tasmanicus

Abstract Amorbus obscuricornis (Westwood) and Gelonus tasmanicus (Le Guillou) (Heteroptera: Coreidae) are specific to Eucalyptus (Myrtaceae). A. obscuricornis feeds almost exclusively upon apical shoots and causes a characteristic wilting and necrosis. By comparison, the feeding activities of G. tasmanicus result in no obvious phytotoxicosis. Salivary gland extracts from both species exhibited sucrase activity but no pectinmethylesterase (PME) activity. Saliva from A. obscuricornis also exhibited considerable oxidase activity. Sucrase activity was significantly higher in extracts derived from G. tasmanicus than from A. obscuricornis, but this could not explain the observed differences in phytotoxic symptoms. It is suggested that differences in plant damage are attributable to the site of feeding activity (i.e. young versus mature tissue), which predetermines the reactivity of host tissues, and/or the quantity of salivary enzymes injected.

The Incidence and Relative Abundance of Amorbus obscuricornis and Gelonus tasmanicus (Hemiptera : Coreidae) in Southern Tasmania and Their Performance on Selected Eucalyptus Species

Comprehensive records of the host-plant associations of Amorbus obscuricornis (Westwood) and Gelonus tasmanicus (Le Guillou), undertaken over three years at field sites in southern Tasmania, are presented for the first time. Also presented are the results of performance experiments conducted predominantly with native Tasmanian Eucalyptus species. Both insect species were found to be oligophagous for Eucalyptus. However, A. obscuricornis was found to feed more widely than G. tasmanicus; that is, the former species fed upon eucalypts belonging to the ash, gum and peppermint groups whilst the latter was confined to the ash and gum species of Eucalyptus in Tasmania. On the basis of collection records, A. obscuricornis was found to be abundant in both wet and dry sclerophyll forest habitats whilst G. tasmanicus was more abundant in wet sclerophyll forests. The wider degree of oligophagy exhibited by A. obscuricornis than by G. tasmanicus is suggested as being related to this species’ preference for floristically diverse habitats, for example dry sclerophyll forest. In addition, inter- and intraspecific host selection in the exclusively shoot- feeding A. obscuricornis was found to be positively influenced by the architecture, in particular the coppicing phenology, of hosts. The significance of factors such as plant architecture, resource abundance and nutritional quality to the host-plant associations of both species are discussed in relation to secondary chemistry and habitat preferences.

Acoustically‐orienting parasitoids in calling and silent males of the field cricket Teleogryllus oceanicus

Abstract. On three Hawaiian Islands, the introduced Australasian field cricket Teleogryllus oceanicus Le Guillou (Orthoptera: Gryllidae) was found to be attacked by the phonotactic parasitoid tachinid fly, Ormia ochracea Bigot. Noncalling males occurred with callers in all locations, but silent males were more heavily parasitized than callers. Body size was unrelated to both calling status and the likelihood of harbouring parasitoid larvae. An experiment examining the likelihood of calling in the laboratory by males collected as silent or calling individuals showed no difference between the two classes of males, after accounting for parasitoid levels; males harbouring larvae were less likely to call.

Xenoencyrtus hemipterus (Girault) (Hymenoptera: Encyrtidae), an Egg Parasitoid of Coreidae (Hemiptera) in Tasmania

ABSTRACTEggs of Amorbus obscuricornis (Westwood) and Gelonus tasmanicus (Le Guillou) (Hemiptera: Coreidae) are reported for the first time as being parasitised by the encyrtid parasitoid Xenoencyrtus hemipterus (Girault). This is the first record of an egg parasitoid attacking these species and is also the first record of the genus Xenoencyrtus Riek from Tasmania. Brief notes on parasitism under laboratory conditions are provided.

An improved soil insect rating for seedling sunflowers

A complex of soil-dwelling insects damages sunflower (Helianthus annuus L.) and other seedlings in Queensland. This paper compares the relative damage potential of the black field earwig, Nala lividipes (Dufour) (Dermaptera:Labiduridae), and crickets Lepidogryllus spp. and Teleogryllus oceanicus (Le Guillou) (Orthoptera : Gryllidae) to sunflowers in laboratory feeding studies. The results were converted to injury equivalents based on documented damage caused by Pterohelaeus alternatus Pascoe (Coleoptera : Tenebrionidae). The injury equivalents were added to the existing multispecies soil insect rating model currently used for other soil-dwelling insect pest species of sunflowers. Populations of additional pest species can now be more accurately assessed for their damage potential before crop planting.

DAILY TRAP CATCHES OF TWO EARWIG (DERMAPTERA) AND THREE CRICKET (ORTHOPTERA) SPECIES IN CENTRAL QUEENSLAND

AbstractDaily light trap catches of Nala lividipes (Dufour), Labidura truncata Kirby (both Dermaptera: Labiduridae), Teleogryllus oceanicus (Le Guillou), Lepidogryllus comparatus (Walker), and L. parvulus (Walker) (all Orthoptera: Gryllidae) from 1 September 1986 to 31 August 1989 at Emerald were recorded. In 1986/87 and 1988/89 more N. lividipes, L. truncata and Lepidogryllus spp. were trapped than in 1987/88. More T. oceanicus were trapped in 1988/89 than the previous 2 years. More females than males were trapped for each species, and for the Dermaptera, more major than minor males. Significant (P < 0.01) regressions of numbers caught were obtained for all species using a multiplicative logistic curve utilising average air temperature and wind‐run as the independent variables, except for T. oceanicus where average temperature alone was suitable. Daily catch numbers for these species are interpreted and discussed from the prediction equations. Further sampling of the Lepidogryllus spp. and N. lividipes over a wider range of ecosystems is suggested. Field sampling should be done concurrently to correlate relative and absolute population estimates.
