Colour black, with dense brown scaling, and with a few very 

 minute setae. 



Head sparsely and shallowly punctured, and with a rounded 

 central impression. Bostrum with shallow punctuation, without 

 carinse, and with the dorsal margins rounded. Prothorax dorsally 

 as long as broad, its sides rounded in the middle, apex not dilated 

 and as broad as the base ; upper surface coarsely punctured, trans- 

 versely impressed and with three deep foveas anteriorly, the central 

 fovea continued to base as a shallow central furrow, but without 

 carinas posteriori}^ ; the sides smooth, with scattered deep punctures. 

 Elytra ovate, shoulders narrow and sloping, sides ampliated, broadest 

 about middle, posterior declivity rounded dorsally ; punctato-sulcate, 

 all the sulci regular except 4 and 5 and the apical part of 2 and 3, 

 which are nearly always confused ; intervals 4, 6 and the apical half 

 of 2 with rows of rather low rounded tubercles, those at the top of 

 the declivity being scarcely larger than the others, interval 2 evidently 

 carinate in the basal half, 3 and 5 each with a short rounded basal 

 costa. Legs with dense brown scaling and short erect setae ; posterior 

 tarsi slender, the first joint about equal to the second.

 which I have examined seven specimens, including Thunberg's type.
