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 25 specimens, male and 

 female, sent me by Prof. T. D. A. Cockerel 1 

 who took them at Las Cruces, N. M. 



This is one of the most beautiful Typhlocy- 

 bids that I have ever seen and I take pleasure 

 in dedicating it to its discoverer.

VIII. Some Xew Ixsects. 



BY T. D. A. COCKERELL. 



COCCID.E. 



Crypticerya, n. subg. — Similar to Icerya 

 s. str., but not forming an ovisac, and with- 

 out the waxy tufts of subg. Crossotosoma. 

 Adapted for living under bark. Type. Icerya 

 roses Riley & Howard. 



Proticerya. n. subg. — Similar to Icerya 

 s. str., but adult $ with only g-jointed 

 antennae. Ovisac large. No conspicuous 

 waxy tufts. Type, Icerya rileyi, n. sp. 



Icerya rileyi, n. sp. — $ dull red, covered 

 with white and yellowish mealy powder, 

 a few small easily deciduous lateral waxy 

 tufts. Ovisac 10 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, 9321 (457S) 6. These differ- 

 ences are not specific, the antennae are 

 variable. Legs and antennae black. For 

 the (T and larval characters see Canad. 

 Entomologist, 1894, p. 34. No further 

 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, X. >[. Agr. Exp. Sta.,

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. Dorytfiyrmex pyra- 

 micHS Rog., attends it. 



Aspidiotus prosopidis, n. sp. — $ scale 

 about 4 mm. diameter; slightly convex, 

 from circular to very broad pyriform, 

 slightly shining, pitch black; exuviae large, 

 uncovered, ridged, black or slightly green- 

 ish 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. 



$ scale oval, larger than that of the $, 

 white, with yellowish exuviae towards one 

 end. The J scales are not ridged, and are 

 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 protub- 

 erance such as is seen in A. personatus. 

 Mouth-parts well-developed. Skin of an- 

 terior 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 rounded, 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 bevond. at long intervals.
