Other longitudinally; eyes large, — their distance apart equal 
above to the length of the basal joint of the antennae (below they 
are very widely separated). Maxillary palpi with the 2nd joint 
equal in length to the greatest width of the apical joint, which is 
very strongly produced on the inner side so as to be transversely 
triangular ; the 3rd joint small and short but angularly produced 
■within. Antennae equal to three-quarters of the body in length ; 
basal joint short and moderately stout, joint 2 very small, 3 quite 
twice as long as 1 and 2 together, 4-6 successively shorter, the rest 
not differing much in length but gradually a little more slender ; 
all the joints after the first rather slender. Mandibles broad and 
slightly notched at the apex. Prothorax slightly -wider than 
long, slightly wider at base than in front, its front angles rounded 
off, its hind angles sKghtly obtuse but well-defined, its sides rather 
strongly rounded, its surface very convex (especially longitudinally) 
and punctured uniformly -with the hinder part of the head. The 
elytra at their base are of the width of the base of the thorax ; 
they dilate gradually to a Kttle behind the middle and then 
contract to the apex, which is acuminate ; the shoulders are quite 
obsolete; each elytron bears 10 punctulate striae of which the 
first is abbreviated ; the punctures in the striae are somewhat 
quadrate and very distinct in front, but become obsolete behind 
the middle ; the interstices are wide and fiattish in front, becoming 
gradually narrower and more convex hindward, and are trans- 
versely rugose and distinctly, but not very closely, punctured ; 
the epipleurae are sub-verticaL The scutellum is rather finely 
and rather closely punctured. The legs are rather stout and very 
long, the hind femora reaching nearly to the ai>ex of the hind 
body. The anterior tibite are angularly dilated within, just above 
the middle in the The anterior four tarsi bear a lamella 
tinder each joint except the last : of the hind tai-si the penultimate 
joint only is laiuellated ; joints 2 and 3 together are on the front 
tarsi slightly longer than, on the middle equal to, on the hind 
shorter than, the first. 
The apical ventral segment in the male is nearly twice as long 
as the preceding segment; a forceps-like appendage projects beyond
