expanded laterally; punctures rather coarse, deep and very close though dis- 

 tinctly sei>arated. Elvira large, two-thirds longer than wide, a little more 

 than twice as wide as the prothorax, quite distinctly wider just behind the 

 middle than at base, the apex somewhat broadly rounded; omoplates large and 

 very feeble; punctures coarse and rather sjmrse, slightly finer toward apex. 

 Abdomen finely, somewhat closely punctate, the pubescence short and very tine. 

 Legs moderate in length, rather stout. Length 3.;> mm.; width 1.25 mm, 



California (Los Angeles). 



Represented by a single female, having a large nubilate paler 

 spot on each elytron at about ai)ieal third. The species is distin- 

 guishable from higuttulus by the peculiar form of the prothorax. 



A male, taken in southern California by Mr. Dunn, is placed 

 with this species for the present, although it (lifters in having a 

 relatively larger, more elongate and less medialh' rounded pro- 

 thorax and nari'ower bodily form ; it is similar, however, in color- 

 ation, being pale, with the head black. This specimen is the only 

 one befoi'e me of the biguttulus gi'oup which has the male organs 

 in auy way protruded, and even here they are only partially visi- 

 ble ; the copulatory sheath has the sides straight and gradually 

 convergent at apex, the immediate tip of the latter prolonged in 

 a narrow acute point ; the excavation of the under surface con- 

 tinues to the extreme acute apex, becoming canaliculate along the 

 produced spiculiform portion ; the portion visible is perfectly 

 straight in profile.

Moderately broad, shorter and stouter in the female, black 

 throughout; tarsi and antenna' toward base paler; elytra each 

 with a small rufo-testaceous spot behind the middle, which is fre- 

 quently almost obsolete ; ])ubescence abundant, moderately long 

 and coarse. Head sub(piadrate, finely but strongly, densely 

 punctate, without impunctate line, the base broadly arcuato-trun- 

 cate, not impressed ; angles broadly rounded ; tempora long, be- 

 coming parallel for a long distance behind the eyes, the latter 

 moderately small, prominent; antenna' rather longer tlian tlu' 

 head and prothorax, moderately incrassate, the tenth joint dis- 

 tinctly longer than wide. Prothorax large, siibequal in width to 

 the head, a little longer than wide, convex, deej)ly, not very 

 coarsely, extremely' densely punctate, widest one-third from the 

 apex, the sides ver^' broadly arcuate, gradually convergent pos-
