Distinguished 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 

 antennje 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.
