Distinguisbed by its depressed form, and the two 
distinct costae of the elytra, which pass through the 
ivory spots, but do not reach the apex ; the latter with 
only one elongate spine. The colour is a light tawny- 
brown, with the antennae and legs rather yellower ; the 
antennae are remarkable for the long and dense fringe of 
hairs which extends nearly to the apex ; the rest of the 
antennae has a shorter pile. The thorax is depressed, 
without punctures apparent through the rather close 
ashy tomentum; the two lateral tubercles, that of the 
middle and that near the anterior angle, and the two 
tubercles on the disc, are all black and nearly equally 
prominent. The twin spots composing the basal spot of 
the elytra are similar in form, the exterior a little the 
longer ; but the middle spots are very unequal ; they are 
level on their front edge, but behind, the exterior one 
passes the other by one-third its length, and they are 
edged with black at both ends.
