Head large, not much produced in front, sparingly covered with small distinct tubercles; eyes large and 
prominent ; antennse moderate, rather slender, yellow. Thorax very large, much dilated at the base, 
longer and much wider than the head; rather closely covered with distinct tubercles, with the interstices 
reticulated and shining; sides rounded and strongly margined, widest at the base; basal margin deeply 
sinuated, with the angles broad and much produced. Scutellum large, triangular, closely asperate. 
Elytra short, much attenuated posteriorly, rufous-brown, not longer and rather narrower than the head 
and thorax, closely but rather lightly asperate; sides nearly straight; apex much rounded, broadly pale, 
with the extreme edge white. Abdomen moderately exposed, rufous-brown. Legs very robust, with the 
basal joints of all the tarsi dilated, bright yellow. Underparts rufo-piceous, with the metasternum and
