teniKE. The male genitalia of the two are ajso virtually identical, 

 but the form of the ungual tooth at once separates them. In the 

 greater number of specimens the sides of the prothorax are less 

 rounded than in any other species, but this character is not always 

 to be depended upon. 



Pedilus serratus n. sp. 



Loujth 6.4-7.8 mm. Black, prothorax, elytra, basal two joints 

 of tne antennip, and legs, except the femora, yellow or rufotesta- 

 ceous. A variety is totally black. 



Antennae longer than half the body in the male, strongly serrate, 

 the apical edge of the intermeciiate and outer joints strongly oblique. 



Head finely, sparsely, evenly punctate; tempora rather short, 

 parallel, coarsely punctate at sicies and beneath. 



ProtJiorax finely, sparsely punctate, the size and spacing of the 

 punct^ires nearly as on the head. 



Elytra closely but not coarsely punctate, pubescence rather con- 

 spicuous. 



Male: Elytra with a small apical subimpunctate blackish area 

 which is broadly, rather flatly impressed; front and middle tarsi 

 feebly dilated; side pieces of oedeagus as in longilohiis. 



Fern ale : Unknown. 



The apical elytral impression occupies the greater part of the 

 small smooth area and becomes gradually deeper toward the 

 suture and tip. The narrow anterior border of the smooth area 

 abov^e the impression is slightly more convex. 



The type is one of three males received from Mr. Nunen- 

 macher, who took them June 11-12 in Eldorado Co., California. 

 One of the three specimens is entirely black. 



Pedilus monticola Horn 

 Trans. Am. Ent. Soc, 1874, p. 41. 

 Length 6.S-1 mm.^ Black, labrum and clypeus — in part, pro- 

 thorax and tip of elytra in the male, reddish yellow. 



Antenna feebly serrate, black, apex of the first joint and the 

 second joint more or less completely pale; barely half as long as 

 the body in the male, still shorter in the female.
