mento niediano area basali nitida: femoribus apice, tibiis tarsisque 

 fusco-ochraceis. Long. 22 mm. 



9.Clypeus strongly depressed from the middle to the apex, 

 apical margin truncate, the raised basal portion slightly porrect 

 and broadly emarginate, with a well defined tooth on each side 

 at the angles of the emargination. Antennas inserted more than 

 one-half as far again from the anterior ocellus as from the base of 

 the clypeus, second joint of flagellum one-half as long again as 

 the third. Head very large, emarginate on the posterior margin, 

 the cheeks a little broader than the eyes. Pronotum not. rounded 

 at the angles, without a depression in the middle; mesopleurse 

 with two small tubercles; first abdominal segment nearly twice as 

 brt)ad as long; pygidial area nearly twice as broad at the base as 

 at the apex, gradually narrowed, and broadly rounded at the 

 apex, twice as long as the greatest breadth, the surface granulate; 

 posterior trochanters with a spine beneath. Head, thorax and 

 median segment closely but not very deeply punctured ; the 

 enclosed area at the base of the median segment smooth and 

 shining, with the usual dividing groove: abdomen opaque and 

 sparsely and finely punctured on the dorsal surface, smooth on 

 the ventral surface.

Type in British Museum. 



Nearly allied to C. perkinsi Turn., but in that species the 

 thorax and median segment are much more sparsely and finely 

 punctured, the abdomen more coarsely punctured, and the 

 pvgidial area not narrowed to the apex; the posterior trochanters 

 without a spine and the tubercles on the mesopleurse less distinct. 

 The size and colour are also different; but the form of the clypeus 

 is very similar. This is the largest known Australian species of 

 the genus.
