Piva, Piel 559 Pl xm, Wiss 6. 
The body is moderately stout, rapidly tapering in front, the head rela- 
tively small; eyes moderately large, circular; beak regularly and gently 
arcuate, slightly incurved at tip, no longer than head and prothorax together; 
antennze, with the joints of the funicle very long and slender, the second 
joint apparently double the length of the first, the whole funicle and club 
together longer than the rostrum. Prothorax fully half as high again as 
long, regularly and rapidly tapering, the surface densely and not very finely 
punctate. Elytra fully twice as long as broad, with distinctly but finely 
punctate stria. Hind femora very long and apically, abruptly, and consid- 
erably clavate, as long as the width of the body; other femora not so long, 
but similarly though less conspicuously clavate; all the tibiee straight and 
slender, the lobes of the last tarsal joint rather small.
