male, separated by a little more than a diameter, impressions rather deep and 
well-marked, orbits impressed. Prothorax broad, hind angles prolonged, em- 
bracing the base of the elytra, in the male frequently broader than the latter, 
in the female of about the same width; feebly convex with two small impres- 
sions at middle of base, side margins reaching anterior third or a little more; 
hind angles finely carinate, more evidently in the male, sides parallel at base 
in male, thence briefly arcuate and very feebly sinuate and obliquely narrowed 
to apex, the latter one-half as broad as base. In the female the sides are rather 
broadly arcuate from base to apex, finely punctate, the punctures separated 
by two or three diameters, a little coarser and sparser on the disk behind the 
middle, finer and still sparser at base, finer toward the hind angles. Elytra 
twice as wide as long, rather strongly narrowed behind in male, less so in female; 
very feebly impressed behind the humeri, less so in female; finely, evenly 
striate with rather close set, elongate punctures, not larger at apex; intervals 
two to five irregularly, finely punctate at basal half, becoming uniseriate be- 
hind; sutural interval irregularly punctate at base in larger specimens, six to 
eight uniseriately punctate, ninth scarcely evidently punctate. 
Prosternum with entire striae, slightly divergent in front, finely, very sparsely 
punctate, the punctures closer anteriorly; flanks of prothorax coarsely and 
closely punctate; meso-metasternal suture fine, metastemum nearly impunc- 
tate at middle, punctures coarser and closer anteriorly and at sides; hind coxae 
finely punctate; first ventral with coarser punctures, other segments rather 
finely, not closely punctate, more closely on last ventral, which is subangulate 
at apex. Length 2.3 to 3 mm. 
I have separated this from chevrolati because of its generally 
larger size, broader thorax, and more narrowed elytra, especially 
in the male. The eyes seem distinctly larger than in chevrolati, 
and are larger in the male than in the female; the cephalic costae 
are stronger and more parallel, the antennal club larger and dif- 
fering more in the sexes. The male has the elytra conspicuously 
fringed with long hairs. In general the species seems to have a 
more northern range than chevrolati, although examples which I 
refer here are before me from the Gulf States. The largest speci- 
mens are from Idaho. 
It is known to me from New Hampshire, Vermont, Massa- 
chusetts, Connecticut, New York, New Jersey, IMaryland, 
Alabama, Arkansas, Iowa, Lake Superior, Montana, Idaho, 
Washington (Spokane Falls) and British Columbia (Caribou). 
[I have given above Mr. Blanchard’s description and remarks 
in full concerning this species, but have substituted, for the specific 
name given by him, that under which Mr. Schaeffer has recently 
described it. H. C. F.]
