REVISION OF TENEBRIONID SUBFAMILY COMONTIN^ III 



ing and converging before basal third, straight and posteriorly 

 converging behind basal third and continuous in direction with 

 the straight and converging sides of the elytra; apex moderately 

 sinuate, nearly two-thirds as wide as the base, the curve of the 

 sinus becoming anteriorlv arcuate and confused with the rounded 

 angles laterally; base almost truncate, the sinuses subobsolete ; 

 surface sparsely, extremely minutely punctate, more evidently but 

 still finely and very sparsely toward the sides, the bead fine 

 though attended by a distinct narrow internal gutter; scutellum 

 rather small ; elytra relatively small, much narrower than the 

 widest part of the prothorax near basal two-fifths of the latter and 

 barely twice as long, gradually rounding and rather acutely ogival 

 behind ; surface nearly smooth, very finely, sparsely punctate, but 

 little more closely or coarsely so laterally, where the margins are 

 rather less narrowly reflexed than in the two preceding ; pro- 

 sternum finely but strongly, not very sparsely punctate, the process 

 wide, strongly dilated and obtusely angulate at apex, strongly 

 beaded but only along the coxaj ; hind femora rather strongly but 

 sparsely punctate, the abdomen minutely. Length 10.8 mm. ; 

 width 5.3 mm. California (SanDiego), — G. W. Dunn. 



cuneata n. sp. 



The last of the above species is one of the more distinct of the 

 genus and differs from the first two, which are northern forms, 

 in being evenly narrowed posteriorly from behind the middle of 

 the prothorax and not solely from the base of the elytra ; it is 

 represented in my cabinet by a single male specimen. 



Group V. — Type subpubescens. 

 This is probably not a perfectly natural group, as it comprises 

 a few species from nearly all the zoological regions of Cali- 

 fornia, differing a good deal among themselves in facies. It is, 

 in general, characterized by a less convex form of body than 

 usual in the genus, although the latter may be stout or as elon- 

 gate as in vtattca, but the surface is generally dull and alu- 

 taceous and always distinctly, though more or less sparsely, 

 pubescent, with the hairs decumbent and not erect and bristling 

 as in the setosa group. In some species, as for example mon- 

 tana, the male is distinctly cuneiform as in the cuneata group 

 preceding, but I have not noticed this character as pertaining to 

 both sexes as it does there. The elytral punctures are more or 

 less small in size and the surface never so rugose as in the 

 eschscholtzi group. The seven species at present known may 

 be differentiated very clearly as follows : —
