I am not certain as to the sex of the unique example of this 



insect. The extremely deep coarse puncturation of the retuse 



part of the pronotum in strong contrast to the fine puncturation 



of the rest of the surface is a very unusual character. The type 



is in the S. Australian Museum among the relics of the Calvert 



Expedition and was taken on the Margaret River. 



N.W. Australia.
