Abstract
About the first of October, Prof. T.D.A. Cockerell sent me for names several parasites bred by him from a Coccid, Phenacoccus cavalliæ Ckll., collected at Rosewel, New Mexico. In the lot where four distinct species of Chalcids, two being new, but one of these in hyperparasite, as follows: (1) Blepyrus phenacocci, sp. nov.; (2) Cheiloneururs dactylopii, How.; (3) Signiphora dactylopii, Ashm.; and (4) Tetrastichus blepyri, sp. nov. The new species are described below:Blepyrus phenacocci, sp. n.– ♀. Length, 1.3 to 1.4 mm. Stature and general appearance similar to B. mexicanus How. Aeneous black, the thimble-like punctuation of the head more or less metallic greenish; antennæ, except the pedicel and the club, all tarsi, and the extreme tips of middle and hind tibiæ, honey-yellow; the pedicel is obconical, about thrice as long as thick at apex, brown-black; the funicle is 6-jointed, the joints transverse, gradually widening to the club, the latter being large, stout and black. Wings hyaline, the tegulæ black, the veins dark brown, the marginal vein very short, hardly twice as long as thick, the postmarginal and stigmal veins long, about equal.
