genera of the family, the process between the coxae moderately nar- 

 row, the mesosternum narrow and divided throughout by a relatively 

 wide parallel sulcus. The hypomera are moderately and indefinitely 

 concave, and the metacoxal lamina short. Belfragei, which is assigned 

 to the genus by Jayne, undoubtedly forms the type of a distinct genus 

 because of the 5-jointed antennal club ; it is therefore not considered 

 in the following table, which comprises all the species known to me : — 



Last joint of the male antennal club short, scarcely one-half longer than the two pre- 

 ceding combined 2 



Last joint much longer, nearly twice as long as the two preceding ; body narrower. ..9 



2 — Last joint conical, pointed at apex 3 



Last joint ovo-conoidal, rounded at apex 8 



3 — Body in great part black or piceous-black in color 4 



Body wholly rufo-ferruginous, stout 7 



4 — Pubescence rather persistent ; zig-zag testaceous bands at basal third and apical 



fourth very narrow and frequently indistinct 5 



Pubescence readily denuded, the rufous bands very wide, the anterior broadly inter- 

 rupted at the suture 6 



5 — Vestiture rather fine, largely black, the suberect bristle-like hairs rather incon- 

 spicuous ; elytral punctures close-set; body moderately stout. Length 3.5-4.6 

 mm.; width 1. 65-2. 1 mm. California (San Francisco to Calaveras). 



jaynei, sp. nov. 

 Vestiture much coarser, the sub-erect bristles conspicuous, the hairs sparser, largely 

 fulvous and whitish, the darker much less numerous ; body less stout and more 

 elongate, the elytral punctures sparse. Length 4.0 mm.; width 1. 9 mm. Guad- 

 alupe Island guadalupensis, sp. nov. 



6— Black areas of the elytra clothed with nearly uniform short blackish pubescence, 

 the rufous bands with sparse uniform fulvous hairs ; body broad, feebly convex, 

 oblong, the elytral punctures rather fine and sparse. Length $ 3.9, 9 6.0 mm.; 



width $ 1.7, 9 2.8 mm. California ampla sp. nov. 



7 — Oblong-oval, convex, the vestiture short but abundant, much variegated, in great 

 part fulvous and white, the suberect black bristles distinct, the white hairs gen- 

 erally forming a distinct cluster at basal and inner third and three detached spots 

 at apical fourth in the zig-zag paler band. Length 4.7 mm.; width 2.2 mm. 



California variegata Horn 



8 — Body rather narrowly oblong-oval, moderately convex, black, the elytra rufous 

 along the lateral edges and rufo-piceous in two narrow obscurely evident 

 bands at the usual positions, the vestiture persistent, nearly as in jaynei, but with 

 the whitish hairs more abundantly interspersed. Length 3.4 mm.; width 1.5 



mm. Nevada (Reno) nevadica, sp. nov. 



9 — Body black, the elytra with the usual two rufous bands clothed with paler, denser 

 and more persistent pubescence, the latter elsewhere readily denuded, the an- 

 terior pale areas more impressed than usual ; punctures of the elytra fine but 

 deep, perforate as usual and somewhat sparse ; prothorax about twice as wide as 

 long in the male. Length 3.6mm.; width 1.5 mm. Utah (southwestern) — Mr. 

 Weidt impressa, sp. nov.
