joining fifth ut base; submarginal humeral carina short, weak; 

 interstices lightl}' convex, eighth carinate at apex: prosternum 

 with intercoxal part angustate (narrow, but not attenuate) 

 anteriorly, sulcate on base; epistei'na very finely transversely 

 striolate; anterior tibiae strongly 4-dentate. Ferruginous brown, 

 legs testaceous. 



Head with front and vertex depressed, finely but distinctly 

 punctate; supra-antennal plates and' wings of clypeus flat; clypeal 

 elevation lightly raised, subtruncate (lightly rounded): clypeus not 

 divided from front, depressed near anterior margin; median part 

 with margin lightly rounded; wings short, wide, strongly advanced 

 beyond median part, external angles rounded but a little marked; 

 supra-antennal plates projecting strongly and sharply beyond 

 wings of clypeus; eyes prominent, convex, very lightly enclosed. 

 Prothorax subquadrate (1'8 x 1-8 mm.), very little narrowed 

 anteriorly (ant. width 1 '65 mm.); disc smooth; basal declivity 

 rugulose; sides subparallel, hardly rounded or sinuate; posterior 

 angles rounded, but lightly marked; anterior margin truncate; 

 anterior angles rounded, not marked; Ijorder reflexed, passing 

 round anterior angles; median and anterior lines well marked; 

 lateral basal impressions rather long, deep, narrow, punctulate. 

 El^^tra wider than prothorax (3-8 x 2 mm.), parallel on sides, 

 widely rounded at apex; base truncate towards sides, emarginate 

 in middle; shoulders rounded, seventh stina entire, not interrupted 

 at beginning of apical curve. Anterior femora short, wide 



Length 7, breadth 2 mm. 



Hab. : North-west Australia (two specimens sent by Mr. 

 Masters); Queensland — Rockhampton (Putzeys; Coll. Castelnau). 



The species on which the above description is founded agrees 

 so well with Putzeys' description of C. cava, that I have little 

 hesitation in regarding it as that species. The strongly i-dentate 

 anterior tibife associate it with (J. hovilhe, Blkb., but the 

 depressed head and the clypeus deeply truncate-emarginate, with 

 wide wings isolate it from all other Australian species. I have 

 not included it among the species of the "■ australadce grouj)," but 

 ha\e felt unwilling to form a separate group for it, so have left it
