 are not much longer or thicker than in D. carinulata, etc. ; the head is 

 smaller than in clathrata, the prothorax more smooth on the upper part, 

 the sculpture of the elytra is finer, particularly behind, where the costae 

 disappear, and the background is densely and finely punctured, the fine 

 costae are sharper, the sutural spines are smaller, the shape of the elytra 

 is about the same, but a little broader and more depressed behind, the 

 colouring is the same, and there is an oblong white patch on each side 

 of the posterior margin."
