Abstract
Imms & Chatterjee in their classical study of the lac insect say : “ In the newly hatched larvae the sexes are indistinguishable by any external characters and it is not until after metamorphosis has set in that the separation into sexes becomes evident. We have examined a large number of the newly hatched larvae of Tachardia lacca and other Coccids and have been unable at this stage to find any external manifestation of the sexes.” There is not a word separating the first from the second sentence of the above statement, yet Negi, in his recent contribution on the lac insect, who also quotes Imms' & Chatterjee's first sentence, erroneously credits the second part of their statement to me. Further, in my paper on lac insects there is a photographic reproduction (Pl. ix, fig. 26) of two larvae of different sexes which are only four days old. Again, figs. 17 and 18, on Plate vi, are male and female larvae, which have been only 24 hours on the tree and are for all purposes identical with crawling larvae.
