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, seriate 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-J.6 mm. California (Calaveras Co.), Colorado 
and Idaho (Cceur d’Alene). pacificus, 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 haiis 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 sutuie, 
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.; width 0.8—1.2 mm. Wyoming (Laramie) and Arizona.

5 _Elytral granules strong and well defined, arranged in even single series along the 
intervals.. 
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, lathei 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 antennae 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
