172 ON THE AUSTRALIAN CLiriSIDES, 



depressed, eighth hardly carinate on apical curve. Anterior 

 femora not channelled below, lower side not dilatate or rounded. 



Length 6, breadth 1 -8 mm. 



/lab. : West Australia— N. W. Coast (?); (sent to me by Mr. C. 

 French). 



A remarkable and isolated species, not nearly allied to any 

 other Australian species. In facies it resembles C. pectoralis, 

 Putz.; its head is much like that of C. hoviUce, Blkb., but the 

 eyes are larger; the form of the clypeus is like that of the species 

 of the " ohliquata group "; the intercoxal part of the prosternum 

 is as wide as in typical members of the " a^ostralasite group." 

 Although I have placed it in the "ohliquata group" it might well 

 be regarded as the type of a new group, of which the characters 

 would be those of the preliminaiy paragraph of the description 

 above.
