anteunal plates convex, bordered externally, divided from clypeal 

 wings by a light sinuosity; eyes prominent. Prothorax convex, 

 as long as broad (1*3 x 1-3 mm.), evidently narrower towards apex, 

 impunctate. Elytra convex (2-9 x 1-5 mm.), widest a little 

 behind middle, strongly punctate-striate; fourth stria joining 

 fifth at base, seventh interrupted before apical curve, deeply 

 impressed near apex; interstices convex, eighth carinate near 

 base. Prosternum with intercoxal part attenuate anteriorly. 

 Anterior femora not swollen on lower side; anterior tibiae tri- 

 dentate with a slight triangular prominence above upper tooth. 

 Length 5-5-6-2, breadth l-3-l-5mm. 



Hah.— (I : Townsville (Dodd). 



This species has the clypeus almost intermediate in form 

 between the species of the australasice- and heterogeria-grouips. 

 It resembles C. vittata, SL, from which it is differentiated by 

 colour (the black of the dorsal surface of the elytra not attaining 

 the apex, and the elytral margins red, not black); head narrower, 

 eyes more prominent; prothorax not finely punctate, &c. From 

 C heterogena, Putz., it differs by head narrow, smooth, with only 

 a few sparse punctures, clypeal " wings " smaller, not straight on 

 outer side, hardly at all divided from the supra-antennal plates; 

 prothorax more convex, impunctate, &c. 



AustralasicH-Group. 



In my '' Revision" of 1896, probably too much importance was 

 attributed to slight differences in the width of the intercoxal part 

 of the prosternum when forming the chief divisions of this group. 

 I now offer a table treating of the australasicB-gvoviY> as a whole : 



A. Prosternum with episterna more or less rugulose-striolate, not punctate. 

 B. Elytra with fourth stria outturned at base and uniting with fifth. 

 C. Anterior tibiae 4-dentate externally. (Intercoxal part of prosternum 

 very narrow or attenuate anteriorly). 

 d. Anterior femora wide, posterior margin of lower side rounded, 

 e. Elytra wholly black, or striped with red on sides. ...C. vittata, SI. 



ee. Elytra red with a black discoidal plaga C. sellata, Putz. 



eee. Elytra wholly testaceous C. inconspicua SI.
