Abdomen somewhat sparsely punctate toward base, the legs very slender. 

 Length 1.9-2.2 mm. ; width 0.65-0.7 mm. 



California (Lake Co.). 



The large series in m}' cabinet shows that this is a species dif- 

 fering from nanus in its larger size, much denser sculpture and 

 deeper color, and, from inscitus, in its smaller eyes, longer and 

 parallel tempora, denser cephalic punctures and less convex 

 elytra. I have before me a single specimen from Alameda Co., 

 which is much stouter than any of those from the above localitv 

 (2.4 by 0.85 mm.), with dense abdominal punctures, and a cloud 

 on each elytron not extending to the suture ; it probabl}^ repre- 

 sents a closeh' allied species.

Narrow, convex, siiining, dark red-brown, the elytra frequently 

 picescent and the nnder surface of the hind body black ; pubes- 

 cence moderately short, coai-se and dense. Head distinctly 

 wider than long, convex, finely, rather closely punctata, with a 

 narrow smooth line, truncate at base, the angles rounded ; tem- 

 pora long and parallel ; eyes very small but prominent ; antennse 

 somewhat stout, feebly incrassate, not quite as long as the head 

 and prothorax. Prothorax convex, about as wide as the head, as 

 long as wide, broadly rounded anteriorly, the sides gradually 

 convergent, becoming less arcuate to a feeble subbasal constric- 

 tion ; punctures fine and deep, but not ver^^ close-set. Elytra 

 elongate, suboval, convex, three-fourths longer than wide, quite 

 distincth^ less than twice as wide as the prothorax ; humeri 

 rather narrowly exposed and rounded; punctures small but strong 

 and close-set. Abdomen finely and sparsely punctate, alutaceous, 

 polished at base. Legs rufo-testaceous, slender. Length 1.8 mm.; 

 width 0.6 mm. 



California (San Jose and San Francisco) and Oregon (The Dal- 

 les). This is a very small and rather remarkable species, which is 

 probably more nearly related to cervinus than to those with which 

 it is here associated. The fifth ventral of the male is unmodified ; 

 the genital segment is large, coriaceous, very broadl}' arcuate 

 throughout its Avidth, not impressed ; the copulator3' sheath 

 seems to terminate in a slender parallel-sided shaft which is 

 abruptl}^ and transversely enlarged at tip but scarcely barbed.
