PL IX, fig. 11. 



Body oblong ovate, broadest at the elytra. Head large, transverse, 

 well rounded, broadest posteriorly, half as broad again as long, with no 

 sign of emargination in front of the eyes, which do not disturb the even 

 contom- of the sides. Prothorax rather short, at its broadest twice as broad 

 as long, broadest at base, with pretty regularly rounded sides, but tapering, 

 especially in front, where it is only a little wider than the head, the sides 

 scarcely if at all marginate ; base apparently regularly truncate, the front 

 rather deeply emarginate; surface both of head and thorax uncertain, but 

 showing in certain places as delicately rugulose in a transverse sense.
