angles. Elytra rather elongate, narrowed from base to apex, 
sinuate-truncate, both angles of the truncature slightly produced; 
surface feebly convex, punctured, light brown, each with eight 
longitudinal lines (besides a short one near the scutellum) of an 
ashy-grey colour ; the second, third, and fourth from the suture 
interrupted a little beyond the middle of the elytron, and leaving 
a considerable space free from lines; towards the apex these 
three lines are represented by a thick streak. Body beneath and 
legs dull reddish, clothed with ashy pile. The legs are rather 
long and stout, the thighs thickly clubbed, the hind tarsi greatly 
elongated, especially the basal joint, which is much longer than 
the remaining three taken together.

Head black, with a few silvery- grey hairs. Antennse black, 
furnished with numerous bristles. Thorax black, with patches 
of silvery-grey pile ; surface sparingly punctured ; lateral spines 
prominent and acute, placed very near the hind angles. Elytra 
oblong-ovate, slightly convex, very briefly and obtusely trun-

line extending from the shoulder to the suture behind the mid- 
dle, and then sharply bent, terminating on the lateral margin ; 
besides this line, there are two short white streaks placed trans- 
versely, — namely, one on the side, at one-third the length of the 
elytron, and the other very near the apex. Body beneath and 
legs dusky. Legs moderately stout ; hind tarsi moderately 
elongated.
