BOLETOBIUS FUNDITUS Sp. llov. 

 PI. VIII. tiy. 3. 



Head long oval, tapering, apparently smooth, piceous. Antennae not 

 preserved. Thorax fully as long as the head, tapering- strongly from base 

 to apex, smooth, piceous. Klytr.v broadening posteriorly, only a little longer 

 than the thorax, and much wider than long, smooth, piceous. Abdomen 

 longer than the rest of the body, a little narrower at base than the elytra, 

 beyond tapering very gently, the tip rounded; the surface is smooth, piceous, 

 almost entirely free from hairs, excepting a short and inconspicuous fringe 

 along the posterior margins. 



This is an ordinary sized species, and appears to be of a uniformly 

 black color and unusually smooth; it is of about the size and form of our 

 B. cinct-un Grav.

BOLETOBIUS DURABILIS sp. nov. 

 PI. VIII, tigs. 4, 5. 



Head small, elongate, half as long again as broad, with nearly parallel 

 sides, smooth, shining, fusco-testaceous. Antenna? not long enough to reach 

 the hinder edge of the thorax, the first three joints long, very slender, smooth 

 and luteous, the first as long as the second and third, which are equal; the 

 remainder dark testaceous, bristly, growing constantly wider, the fourth as 

 long and nearly as slender as the third, and lighter in color than the others, 

 the fifth, sixth, and seventh nearly quadrate, the remainder broader than 

 long, the apical subglobose. Thorax much broader than the head even at 

 tip, tapering but little, with rounded sides, scarcely so long as the head but 

 nearly twice as broad as long, smooth and luteous. Legs too poorly pre- 

 served to admit of statement. Klytra as broad at base as the thorax, 

 broadening considerably on the basal half, slightly longer than the head 

 and thorax together and longer than broad, smooth, luteo-testaceous. Abdo- 

 men almost as long as the rest of the body, as broad at base as the elytra, 

 with parallel sides on the basal half, nan-owing beyond to a rounded tip, 

 sparsely covered with bristly hairs, almost as frequent over the whole sur- 

 face as on the apical edges of the segments.
