 of prothorax, and all the legs gone, and the elytra a little broken. The pro- 

 thorax is profusely and uniformly pitted with moderately shallow pits, 

 averaging .Oli""" in diameter ; the elytra are traversed by longitudinal 

 cost:v, five of which arc much more prominent than the others, with 

 *harp, unbroken edges and equidistant from one another, the outer ones 

 in close proximity to the sutural and outer edges; the other costjc are 

 obscure, slightly elevated, rounded, broken to a greater or less extent into 

 raised point- : midway between tin- tirst and second prominent costa- (count- 

 ing from the outer margin) there is an exactly similar prominent costa on 

 the basal third of the elytron ; the prominent costic are 0.2""" apart. 



Length of tin- prothorax, 0.88""" ; height of same, I.o4 nini : length of
