B. CANADENSIS, Brendel. Piceous-brown or piceous-black, 
pubescence moderately long, recumbent. Elytra sanguineous. 
Legs and antenne ferruginous. 
flead as long as wide, the eyes excluded, punctured, more 
strongly at the sides behind the tempora, the later convergent, 
little longer than the eyes, feebly arcuate; fovez large, equal 
in size, the posterior ones mutually three times as distant as 
either from the eye; antennal tubercles prominent, with a few 
coarse punctures; frontal margin convex, the space between 
the antennal tubercles concave, bearing the frontal fovea, and 
here more conspicuously pubescent; eyes coarsely facetted, 
by their own length distant from the frontal margin. <Azten- 
ne from the first to the eighth joint sub-cylindrical, decreas- 
ing gradually in length and thickness, except the fifth, which 
is a little longer than its neighbors; the eighth smallest, quad- 
rate. Prothorax uniformly very conspicuously and deeply 
punctured, one-third broader than long, widest in the middle, 
where it is strongly arcuate, from there to the anterior and 
basal margin straight; anterior margin one-half the length of 
the base; middle fovea nude, about double as large as the 
discal punctures; lateral fovea large, fully visible from above 
and situated with the anterior margin just behind the middle; 
the base is garnitured with oblong punctures. Elytra across 
the shoulders as broad as the prothorax, sides arcuate, diverg- 
ing, suture one and one-half times as long as the prothorax 
and three-fourths as long as the width across the tip; disk 
strongly punctured, all the impressed lines entire, the sutural 
ones arcuate near the tip and finely punctured, the discal lines 
convergent toward the tip; basal fovee three, large, the 
sutural one farther from the base than the middle one. Addo- 
men moderately convex, more feebly punctured, the pubes- 
cence as long as on the elytra, first segment as long as one- 
third its width, the lateral reflexed margin not broader and 
the lateral basal impression much larger than in B. rubicunda, 
the basal striez strongly divergent more than half as long as 
the segment, including at base a space not broader than the
