callous spots feeble, the angular nodes well developed and as long as the interval 

 thence to the spicules, which are very minute ; elytra two-thirds longer than wide, 

 more than three times as long as the prothorax, rather finely but deeply, not 

 very closely punctate ( 9 )■ Length 2.0 mm. ; width 0.88 mm. California 

 (near San Francisco) inscitus, sp. nov. 



Antennal club narrow, with its basal joint distinctly smaller than the second ; body 

 small, oblong, compact and convex, shining, dark rufo-testaceous in color, the 

 vestiture rather long and abundant, suberect and distinct ; prothorax large, about 

 as wide as the elytra, strongly, very closely and deeply punctato cribrate, nearly 

 even, the posterior of the callous spots alone distinct ; sides parallel, very feebly 

 narrowed at base, the angular nodes well developed and as long as the adjacent 

 sinus, the spicules strong and distinct ; elytra about three-fifths longer than wide 

 and two and three-fourths times as long as the prothorax, not very coarsely, but 

 deeply and quite closely, punctate ( ^ )■ Length I.S mm.; width o. 78 mm.

cribricollis, sp. nov. 



22 — Body normally convex, pale ferruginous in color throughout, the nodes of the 

 thoracic angles well developed but not prominent and not unguiculate behind. .23 



Body sensibly depressed, blackish in color, the legs piceous, the head and pronotum 

 rufo-piceous ; thoracic nodes smaller but much more prominent, strongly acute 

 and unciform behind 24 



23 — Body oblong-oval, rather stout, the antennal club moderately wide, with the 

 middle joint just visibly the widest, the pubescence very short and even, somewhat 

 sparse ; eyes rather large and not very convex ; prothora.x well developed, the 

 angular nodes moderate in size, not more than a fifth of the total length and very 

 much shorter than the distance thence to the spicules, which are small but dis- 

 tinct, the sides between them and the nodes broadly sinuate ; punctures close-set, 

 the anterior callous spots small but abruptly elevated and very distinct, the pos- 

 terior almost obsolete ; elytra large, distinctly wider than the prothorax and more 

 than three times as long, the punctures moderately coarse and somewhat close- 

 set ( J ). The male is shorter, with more finely and densely punctate prothorax 

 and elytra. Length 2.0-2.4 mm. ; width 0.88-I.0 mm. California (Sta. Cruz 

 Co.) brevipilis, sp. nov. 



Body nearly similar in form and color but with the eyes rather smaller and more convex, 

 the thoracic lobes larger, about a fourth of the total length and but little shorter 

 than the sides thence to the spicules, which portion is straight, the callous spots 

 less distinct; elytra unusually finely and quite closely punctured; pubescence rather 

 longer than in brevipilis but nearly even and decumbent (9). Length 2.25 

 mm.; width 0.9 mm. California (exact locality not recorded). 



lepidus, sp. nov. 



24 — Broadly oblong-oval, feebly shining, the antennal club moderate and the eyes 

 quite small and strongly convex ; prothorax relatively rather small but not very 

 transverse, about three-fifths wider than long, unusually finely and very densely 

 punctate, the callous spots very small and inconspicuous, the sides parallel, arcu- 

 ately narrowing toward base, the spicules broad and truncate, unciform behind, 

 the angular lobes rather small but very prominent, obliquely, rectilinearly truncate 

 from above ; elytra large, black, evenly rounded behind, nearly a fourth wider
