VIII. Some New Insects

International Journal of BY T. D. A. COCKERELL. inner apical cell. The venation of the wing is peculiar in that the posterior apical cell is very small. All beneath pale yellow. Described from 2 5 specimens, male and female sent me by Prof. T. D. A. Cockerell who took them at Las Cruces, N. M. - Crypticerya, n. subg.uSimilar to Icerya s. str., but not forming an ovisac, and without the waxy tufts of subg. Crossotosoma. Adapted for living under bark. Type, Icerya rosw Riley 8 Howard. Proticerya, n. subg.--Similar to Icerya s. str., but adult with only 9-jointed antennae. Ovisac large. No conspicuous waxy tufts. Type, Icerya rileyi, n. sp. Icerya rileyi, n. sp.u dull red, covered with white and yellowish mealy powder, a few small easily deciduous lateral waxy tufts. Ovisac io mm. long, 5 broad, white with a slight yellowish tinge, smooth, not fluted, obscurely longitudinally grooved beneath. Antennal formula of a specimen from Mesquite, 9 (35) 21 (46) (78), of one from Larrea, 932t (4578) 6. These differences are not specific, the antennae are variable. Legs and antennae black. For Entom’ologist, t894 p. 34. No further the and larval characters see Canad. description is given at this time, as it is hoped to describe and figure the various stages from fresh material hereafter. The insect will be very easily recognized by the characters now cited, especially if reference is also made to the descriptive notes of Prof. Townsend,_Bull. 7, N. M. Agr. Exp. Sta., P.5. Hab.--Las Cruces, N. M., common on Mesquite (Prosopis) and rather rare on Creosote bush (Larrea). It is attacked by Laetilia and an apparently new species of Coccinellidae. This interesting species was to have been described by Dr. Riley had he lived; in his opinion, it represented a valid new genus. The ant, Dorymyrnex yramicus Rog., attends it. Aspidiotus prosopidis, n. sp.-- scale about mm. diameter; slightly convex, from circular to very broad pyriform, slightly shining, pitch black; exuviae large, uncovered, ridged black or slightly greenish or brownish, central. The exuviae are remarkably large for the size of the scale. Removed from the bark the scales leave a broad whitish ring with no black ring. end. The scales are not ridged,.and are scale oval, larger than that of the white, with yellowish exuviae towards one of the same’texture as those of the extremely small, after boiling in soda transparent, tinged with yellowish-brown, circular in outline, not visibly segmented, anterior end with a large rounded protuberance such as is seen in A. ersonatus. Mouth-parts well-developed. Skin of anterior portion transversely reticulately wrinkled. No grouped ventral glands. Lobes extremely small, two pairs, median rounded, nearly as far apart as the diameter of one. Second lobes also roundedl but broader and lower than the median, nearly as far from them as the diameter of one. A spine close to each lobe, and three on the margin beyond, at long intervals. Plates hardly visible. Anal orifice about as far from base of median lobes as its longer diameter. A contains two long-oval embryos, which are extraordinarily large, more than half as long as the diameter of the ?. The last joint of the antenna of the embryo is as long or a little longer than the three before it together. H’ab.On Mesquite (Prosopis), numerously infesting the small twigs. Found by Prof. Toumey about 4 miles west of Phoenix, in Salt River Valley, Arizona, Sept. x895. This singular little species,has the scale completely enveloping the and so would fall in Signoret’s subgenus Targionia. In several characters it resembles A. bersonatus, but it is very distinct from any species described. It might have been thought that the specimens were not adult, had not matured embryos been found. It is found on the leaves as well as the twigs. Dactylopius pandani, n. sp.-- 3 ram. long, x broad, pale yellowish brown. Legs and antennae very pale yellowish brown. Margin with stout cottony tufts as in 29. cirri. Dorsum covered with white meal. turns reddish on boiling in soda, but gives no crimson color. It becomes almost colorless, but the contained embryos remain bright yellow. Antennae 8-jointed, joints with whorls of hairs, joint unusually long, even a little longer than 2; 2 subequal with 3 4 to 7 equal and shortest; 8 about as long as I. Formula (18) (23) (4567), but itmight almost as well be written (I823) (4567 Rostal loop reaching to level of base of second pair of legs. Legs ordinary, tibia of anterior legs about longer than tarsus of middle legs only about 1/4 longer. Femur + trochanter a little longer than tibia + tarsus. Claw small. Digitules slender, those of claw with conspicuous round knobs, those of tarsus with very small knobs. Trochanter with a long bristle. Posterior tubercles hardly noticeable, each bearing a bristle only about 1/4 longer than those of the anal ring. Anal ring with the usual 6 bristles. Eyes prominent, elevated on a stout base. Six patches of small spines o (...truncated)
