Typ. in coll. mea. 



Medium-sized species, black, rather densely clothed with longish 

 silvery hairs, which are longer on the head and thorax than on the 

 elytra. The head is very wide, being much wider than the thorax, 

 and in some specimens as wide as the elytra at their base, and with 

 the tempora much inflated making the head above the eyes as wide as 

 it is across the eyes themselves. Eyes not prominent. The head and 

 thorax are finely punctulate, the latter with a median fovea situate 

 somewhat in front of its posterior third. Antennoe with first two 

 joints black, the remainder being a very dark brown. Scutellum long 

 and narrow. Elytra black with yellow markings arranged as follows : 

 on each elytron a broad dorsal vitta (one-fourth as wide as the elytron) 

 not reaching to the middle of the el3rtron; another narrower marginal 

 vitta reaching fully to, or rather beyond, the middle; behind the apex 

 of the dorsal vitta and occasionally coalescing with it a large dorsal 

 spot, irregular in outline but always transverse; behind this spot, 

 midway between it and the apex of the elytron, an irregular yellow 

 band. The legs and abdomen are densely clothed with long silvery 

 hairs which are more abundant on the femora and tibiae.
