Middle California. The black form occurring in the San Francisco 

 Bay region may therefore, I think, be safely regarded as typical. 

 Along with them, and even more abundant, judging from the ma- 

 terial at hand is found the pale form — var. flavidiis. Farther east, 

 in the foothills of the Sierras, from Tehama to Tulare Co., the 

 flavidiis form alone prevails, at least there are no black examples 

 from this region in the material examined. Farther to the North — 

 in Siskiyou Co. the black form and a dusky pallescent variety of it 

 occurs, while throughout Southern California the black form alone 

 is found. These Southern California specimens, when compared 

 with those from Middle California, appear as a whole to be smaller 

 with relatively slightly shorter elytra and stouter antennae. The 

 dusky pallescent male from Siskiyou Co. has the antennae distinctly 

 shorter than in the typical form, but in a black male occurring 

 with it, this disparity is less obvious.

Pedilus picipennis n. sp. 



Length 5-6.8 mm. Black, typically with the elytra, antennae, 

 tibiae and tarsi paler, varying from piceous to pale brown; more 

 rarely almost uniformly black throughout. 



Antenna moderately serrate, distinctly longer than half the body 

 in the male. 



Head finely, sparsely punctate; tempora parallel, coarsely punc- 

 tate at sides beneath. 



Prothorax finely sparsely punctate. 



Elytra rather finely and densely punctate, 



Male: Elytra completely unmodified at apex; fifth ventral seg- 

 ment more strongly emarginate than usual; front and middle tarsi
