TENEBRIONID.'E 155 



as long. Length (cf) 24.0-25.5 mm.; width 8.8-9.3 rnm. Cali- 

 fornia. (The type example bears one of Mr. Dunn's labels, having 

 written upon it in red ink "Rey," which I have understood to mean 

 Monterey, a rather extreme northern habitat for any of the allies 

 of angulatus. The other two specimens are labeled simply "Califor- 

 nia.") gravidipes n. sp. 



Body elongate-oval, black and opaque; head very sparsely punctate; 

 prothorax a third wider than long, rather widely and acutely mar- 

 gined, the surface very feebly convex, sparsely punctured medially, 

 more coarsely and densely at the margin, the sides strongly rounded, 

 subangulate at the middle; apex deeply emarginate, the angles acute 

 and prominent; base bisinuate, the angles obtuse; elytra elongate- 

 oval, without marginal costa or ridge, the humeral angles rounded; 

 surface very faintly subtricostate; prosternum truncate. Length 

 17.0 mm. California (Owen's Valley). [Asida luctata Horn]. 



luctatus Horn 



The elytra in the first section are evidently less convex and in par- 

 ticular more depressed toward the sides basally in the male than in 

 the female, but this character is not at all apparent in the angulatus 

 section. Crassus is a species altogether isolated in general appear- 

 ance, with side margins of the prothorax almost as fine and feebly 

 marked as in group VI. Luctatus is evidently out of harmony with 

 the rest of the angulatus group in several published characters and 

 in all probability will prove to form the type either of a distinct 

 group of Euschides or a separate genus. The allusion to a truncate 

 prosternum in luctatus is not altogether clear, for, if that part be- 

 tween the coxae is posteriorly porrect and subhorizontal to the tip, 

 the species would evidently form a separate genus allied to Steth- 

 asida and be widely out of place here, where it was placed by its 



author. 



Group VI Type convexicollis Lee. 



With a form of body strongly resembling, in its smaller prothorax 

 and obovately inflated hind body, the next or obovatus group, though 

 markedly more convex, the few species of this group possess two 

 highly distinctive features, the first relating to the side margins of 

 the prothorax, which, instead of being deplanate or concave as in 

 all the preceding groups, are here very fine and extremely narrowly 

 and steeply declivo-subexplanate; the second concerning the eyes, 

 which are notably larger than in any other type of the entire Asidini 

 as yet coming under my observation. The eyes are, as usual,
