Nearly black: sparingly clothed with pubescence, which is chiefly 

 brown, but on the shoulders of the elytra, the basal segment of tho 

 abdomen, and the margin of the penultimate segment, and on the tibisB is 

 golden. Head, thorax, and elytra densely and very strongly punctured, 

 the punctures on the disk of the thorax having a tendency to run 

 together longitudinally. Tho punctuation of tho abdomen is much less 

 strong and less close. Head a little broader than long, about two thirds 

 the width of the thorax ; the cheek behind each eye is much less than the 

 length of the eye, the posterior angle rounded. Thorax rounded at the 

 sides and behind ; in the middle of the base there is a short smooth spot. 

 Elytra as long as the thorax, but distinctly broader, with an indication
