width of the head. Prothorax not quite as long as wide, the apex broadly arcu- 

 ate, the sides becoming parallel and feebly arcuate near the base, serrate through- 

 out, rather strongly at the rounded basal angles and still more coarsely around 

 the apex ; base broadly lobed ; surface with small, strong and isolated granules 

 throughout, intermingled anteriorly with some larger sparse asperities. Scu- 

 tellum small. Elytra not quite twice as long as wide, more than twice as long as 

 the prothorax and slightly wider ; surface with series of moderately coarse punc- 

 tures, confused near the suture and smaller and less seriate on the flanks ; inter- 

 vals asperate ; apex evenly convex, with the punctures confused and asperate. 

 Abdomen shining, sparsely punctulato-rugose and finely, sparsely pubescent. 

 Length 4.0-4.8 mm ; width 1.3-1.6 mm. California (Calaveras Co,), Colorado 

 and Idaho (Cceur d'Alene) paciflCUS, sp. nov. 



Elytra with less coarse and more impressed punctures, nearly as in pacificus and not 

 larger than the width of the intervals, the latter perfectly even, polished and 

 devoid of tubercles or asperities throughout. Body deep black, the erect hairs of 

 the elytra rather short. Head dull, sparsely pubescent, the epistoma broadly 

 sinuate. Prothorax not quite as long as wide, arcuately swollen toward base, 

 broadly rounded and asperato-tuberculose at apex ; disk granose toward base. 

 Elytra slightly wider than the prothorax, rather short, four-fifths longer than 

 wide, the punctures seriate in arrangement, densely confused near the suture, 

 more broadly toward base, small and irregular in arrangement toward the side 

 margins, the apical declivity evenly convex and not at all granulose though more 

 closely and unevenly punctate. Abdomen shining, sparsely punctulate. Length 

 2.7-3.7 mm -j width 0.8-I.2 mm. Wyoming (Laramie) and Arizona. 



sobrinus, sp. nov. 



5 — Elytral granules strong and well defined, arranged in even single series along the 

 intervals 6 



Elytral granules subobsolete except on the declivity, the punctured series contiguous, 

 with the intervening ridges narrow and alternately slightly stronger 7 



6 — Elytra roughly and densely punctate on the declivity, the tuberculose intervals 

 equal throughout, finely and confusedly on the flanks. Head short and transverse, 

 granose, the basal constriction exposed as usual ; eyes small ; antennae short, the 

 club paler; epistomal suture subobsolete. Prothorax slightly shorter than wide, 

 nearly as in pacificus. Elytra not quite twice as long as wide, rather wider 

 than the prothorax, the lustre dull, the sculpture coarse and rough, the punctures 

 of the series large, deep and approximate but circular and well defined, except at 

 the sides. Abdomen minutely, sparsely punctulate, feebly pubescent. Length 

 4.0 mm.; width 1.4 mm. New Mexico (Fort Wingate) . . . asperulus, sp. nov. 



Elytra finely, evenly and strongly granose on the declivity; intervals separating the 

 punctured series equal in elevation ; punctures of the series coalescent and not 

 well defined. Head short and transverse, finely granose, the labrum declivous, 

 the eyes and antennte moderate. Prothorax not quite as long as wide, broadly 

 rounded and strongly asperate anteriorly, the sides feebly diverging to the 

 rounded and asperate basal angles ; disk with the granules equal, strong and 

 isolated toward base. Elytra but little wider than the prothorax, scarcely twice 

 as long as wide, densely sculptured in even series, except near the suture and
