strongly impressed stri^e of moderately coarse deep elongate punctures, the 

 intervals equally convex, becoming somewhat acute toward apex, finely and 

 unevenly punctate along the sides of the grooves. Abdomen finely, rather 

 sparsely punctate. Legs short, the femora very robust, the denticle strong ; 

 tibiae stout, bent toward base, enlarged toward, and externally prominent at, 

 the apex. Length 3.8 mm. ; width 2.0 mm. 



Texas. 



A rather small, evenly convex and isolated species, having the 

 eyes much more widely separated than in any other form which I 

 have seen. The structural characters are, however, all of this 

 genus. The ocular lobes are moderately well developed as usual in 

 this group. 



Chalcodermus includes but three species within our faunal limits, 

 — seneus, insequicoUis, and collaris. The species identified by 

 LeConte as spinifer Boh., belongs to a widely different tribe of 

 Curculionidffi. 



CHAI.EPO]¥OTUS n. gen. 



This genus is allied to Chalcodermus, but differs in the following 

 characters : — 



Antennal scrobes feebly descending to the lower angle of the eyes, the basal 

 joint of the funicle not as long as the second. Second abdominal segment 

 much longer than the next two combined, the suture broadly, evenly angu- 

 late throughout its width. Middle coxse widely separated. Tarsal claws 

 small, slender, approximate at base but not at all connate. 



It also differs in many other features, the body, for example, being 

 more finely sculptured, aud the elytral intervals elevated as in many 

 species of Ryssematus. The mandibles are very thick, strongly, 

 evenly arcuate in external outline, the apex prolonged and acute. 



C elllSllS n. sp. — Oval, convex, shining, black, glabrous; each puncture 

 bearing a vnry minute seta. Head finely, not very densely punctate ; eyes 

 rather distant, separated by nearly their own width on the front ; beak rather 

 slender, cylindrical, evenly, feebly arcuate, as long as the head and prothorax, 

 finely, sparsely punctate, shining, the antenn?e inserted a little beyond the 

 middle, the second funicular joint elongate, fully as long as the next two, 

 outer joints thicker, the seventh scarcely as long as wide, club scarcely longer 

 than the three preceding joints, oval, pointed, not very abrupt. Prothorax 

 scarcely more than one-fourth wider than long, subconical, the sides evenly 

 convergent and broadly arcuate from the base to the distinct but not strong 

 subapical constriction, the apex arcuate, a little more than one-half as wide 

 as the base ; disk finely, deeply and evenly punctate, the punctures separated
