REVISION OF TENEBRIOMD SUBFAMILY CONIONTIN^ II5 



sparsely punctate, becoming moderately coarsely and rather less 

 sparsely so laterally; under surface and hind femora finely, 

 sparsely punctulate, the presternum more strongly, with the 

 process unmargined except feebly along the coxae ; tarsi unusually 

 slender. Length 7.0-S.o mm.; width 3.4-3.9 mm. California 

 (San Diego). Two specimens taken by the author and one sub- 

 sequently received, the latter having the scutellum much more 

 transversely triangular and the body a little more convex. 



parviceps Csy. 



Body somewhat less cylindrical, oblong-oval, distinctly more de- 

 pressed, nearly similar in coloration, lustre and pubescence; head 

 even smaller and less developed than in any other species, less 

 coarsely but strongly, rather closely punctate, the sinus rather 

 broader, the anterior canthus more obliquely pointed, as promi- 

 nent as the posterior ; prothorax much shorter but otherwise 

 nearly similar, two-thirds wider than long, the deep apical sinus 

 parabolic, almost similarly sculptured but not quite so coarsely, 

 the marginal bead fine, arcuate at base ; scutellum rather small, 

 similar, only feebly transverse and sharply triangular ; elytra about 

 two and one-half times as long as the prothorax, less than one- 

 half longer than wide, more gradually and acutely ogival in apical 

 two-fifths; surface more strongly undulato-rugulose, especially 

 behind, with a medial vaguely eroded line on each, the punctures 

 rather smaller and less sparse than in parviceps ; prosternum 

 rather strongly, moderately closely punctured, the process strongly 

 margined, obsolescently so around the broadly arcuate apex; hind 

 femora and abdomen finely and rather sparsely but strongly and 

 distinctly punctate. Length 7.8 mm. ; width 3.7 mm. Califor- 

 nia (Poway, San Diego Co.) filiola n. sp. 



The last two species of the table form a rather isolated type, 

 peculiar to the Sonoran regions of California. 



Group VL — Type setosa. 



The following five species form a natural group leading to 

 eschscholtzi and allies, having the same rather stout and oblong 

 convex body, but with the elytral sculpture comparatively fine 

 and always less coarse or rugose and the more or less con- 

 spicuous vesliture erect and bristling on the elytra ; they have 

 a geographic distribution differing greatly from that of the 

 eschscholtzi group but coincident with that of the ovalis group 

 and may be thus defined : — 



Prosternal process not or but feebly dilated behind the coxje 3 



Prosternal process more constricted at the coxie and always more or 

 less strongly dilated apically 5 



2 — Elytral vestiture short 3
