larger depressions, two near sides, two near base. Elytra wider 

 than prothorax at base, and four times as long, shoulders rounded, 

 sides gradually widening till near the apex, the latter unarmed: 

 lateral border and channel very narrow but continuous to apex, 

 epipleurae continuous almost to apex, the whole surface evenly 

 but not very closely dotted with small setiferous punctures, 

 becoming smaller towards apex, a single lateral row of close large 

 punctures. Abdomen with finer setiferous punctures than on 

 elytra, the hairs arising therefrom adpressed and of a lighter 

 colour; epipleurre and episterna coarsely punctate, prosternum 

 carinate and sharply produced behind, submentum transversely 

 rugose. Hind tarsi with basal joint as long as the rest combined.

I lab. — A ustralia. 



A single female specimen in the South Australian Museum, 

 labelled Australia, Blackburn Coll., is distinguished from its 

 allies by the combination of brilliant colour, and depressed form, 

 and the punctures of elvtra evidently smaller than in C. Mastersi 

 Macl., and C. victoriensis Blackb. A second specimen in the 

 British Museum consignment to me, labelled S. Australia (F. 

 Bates, 81, 19).

 short, basal joint securiform; maxillary palpi long and robust, 

 last joint large and securiform. Epistoma truncate in front, 

 rounded at sides, canthus arcuate, raised and concave within, 

 limiting suture clearly defined and arcuate. Eyes large, reniform,
