Chlamys confusa new species. 



Similar in form, color and sculpture to memnonia Lac. but the elytral 

 tubercles and ridges are less strongly developed, the prothoracic crest is lower 

 and less deeply impressed, the true scutellum narrower and the second, or 

 metascutellum, rarely as distinct a9 in that species and sometimes absent. At 

 the bottom of the emargination of the eyes is an orange-yellow spot as in 

 plicata and tuberculata, which is absent in memnonia and prosternalis. 

 Length 4 mm. 



Huachuca Mts., Arizona. 



Besides the less developed elytral tubercles and ridges the small, 

 yellow spot inside of each eye separates this species readily from 

 memnonia. 



The elytral sculpture varies to some extent but is in the largest 

 specimens never as strongly developed as in typical memnonia. It is 

 possible that this species is the same as ma?stifica Lac, which was 

 described from specimens from Mexico and also two from California. 

 However, none of my specimens do exactly agree with Lacordaire's 

 description of mccstifica. 



In Biol. Cent. Am., Col. vol. VI, pt. I, p. 75, Mr. Jacoby p3)aces 

 Chlamys memnonia rather doubtful in the genus Diaspis. The prin- 

 cipal characters of this genus are the possession of a second scu- 

 tellum, termed by Lacordaire the metascutellum, and the bifid claws. 

 In C. confusa, the second scutellum is almost absent or very faint in 

 a few specimens and Linell mentions a specimen of C. plicata with a 

 second scutellum so this character becomes valueless and there re- 

 mians only the bifid claws. These are in memnonia. confusa and 

 prosternalis broadly appendiculate at base as in plicata and these 

 species cannot be placed properly in Diaspis. 



Urodera texana new species. 



Rather shortly oval, black, elytra reddish-yellow, except suture margin 

 narrowly and an oblique, arcuate median band black. Head nearly smooth 

 with only a few small punctures which are near the eyes larger. Prothorax 

 about one and one half times as wide as long; median basal lobe not reflected: 

 surface sparsely and rather finely punctate. Scutellum smooth. Elytra with 

 rows of rather fine punctures ; intervals smooth, except for a few very small 

 adventitious punctures. Underside and pygidium rather closely punctate and 

 covered moderately densely with short greyish-white hairs. Length (from apex 

 of prothorax to apex of elytra) 6 mm., width 4.25 mm.
