than wide, not perceptibly Avider than the prothorax, the sides straight and 

 snbparallel; apex rather broadly rounded; disk finely and relatively not very

 Length 3.0 mm. ; Avidth 1.2 mm. 



California. 



The male described as the type has the fifth ventral feebly' sin- 

 uato-truncate at apex; it is the only specimen known to me. 

 The species is allied to hirtellus, but may be easil}' distinguished 

 by certain peculiarities of vestiture and coloration, the tip of the 

 elytra not being rufescent and the erect sette blacker and sparser.

 (Pristoscelis). 



Oblong, convex, polished, black, with a feeble grayish-metallic 

 lustre ; elytral apices pale ; coriaceous hind margins of the ab- 

 dominal segments and tip of the fifth pale ; legs and antennaj pale 

 rufo-ferruginous throughout ; pubescence rather long, coarse and 

 dense, pale luteo-cinereous, with long erect and sparser hairs brist- 

 ling from the upper surface, these largely black anteriorly but 

 cinereous at the edges, pale on the elytra sparsely intermingled 

 with blackish on the disk. Head three-fourths as wide as the 

 prothorax, strongly and rather densel}* punctate ; epistoma mod- 

 eratel}' long, pale and polished ; labrum completeh' pale, strongly 

 rounded ; e^-es moderate, not attaining the base ; antenna? long, 

 and slender, serrate, much longer than the prothorax, the penulti- 

 mate joints fulh' as long as wide. Prothorax rather smalland 

 transverse, one-half wider than long, the sides arcuate, convergent 

 anteriorly, the angles all obtuse and rounded ; apex and base 

 broadly and feebly arcuate, the former distinctly the narrower ; 

 disk rather finely, not denseh' punctate, not rugose at the sides. 

 Elytra oblong, one-half longer than wide, one-third wider than 

 the prothorax, parallel, broadly rounded and almost truncate at 

 apex, finel}^, strongly and somewhat denselj' punctured. Length 

 2.5-3.2 mm.; width 1.1-1.3 mm. 



Lower California (Cape San Lucas). The specimen described 

 is a female, havinsf the fifth ventral rounded behind, though 

 broadly so, and the tibial spurs simple. I have two males from 

 Arizona which are apparently assignable to this species, and in 

 these the head and prothorax are almost the same in rela- 

 tive size and shape, but the prothorax is larger and wider when 

 compared with the elytra. The slender antenniv, elytral colora-
