164 NOTES ON AUSTRALIAN COLEOPTERA, 



indistinct row of punctures outside the 9th interval; humeri 

 rounded, showing carinate epipleural fold, underside smooth, 

 tibiae near apex and tarsi with red tomentum. Dimensions: 



g 15 x5 mm., 2 17x0 mm. 



Hob. — Wingham, N.S.W. (W. DuBoulay). 



I am indebted to Mr. DuBoulay for specimens of this, three 



of which are under examination. The sexual differences are as 

 in C. rugosus Cart., i.e., £ with narrower form, humeri squarer 

 and more prominent, hind tibiae thinner. It also resembles C. 

 ruyosv>8 in the form of the prothorax, but may be easily dis- 

 tinguished from that species by the less widely rounded sides of 

 prothorax, with sharper anterior and wider posterior angles, the 

 last less outwardly directed, while the elytral intervals are not 

 undulate, nor do the sulci contain punctures.
