and also bears a system of coarser (but not very coarse) punctura- 

 tion which is rather evenly distributed (except on the hinder part 

 of the disc where it fails), and is not much coarser on the sides 

 than elsewhere. The elytral sculpture is scarcely enfeebled towards 

 the apex. The interstices are for the most part very evidently 

 convex but in an irregular fashion some parts of the same inter- 

 stice being more convex then others^ and the convexity being here 

 and there extended laterally so as almost to interrupt the stria- 

 tion ; all these irregularities however are feeble and not at all 

 sharply defined, but they give the elytra a somewhat blotchy 

 appearance. Compared with C. repens^ Germ., this species (apart 

 from colour differences) has the antennae much more slender, the 

 joints of the same differently proportioned inter se, the prothorax 

 less transverse and differently punctured, the elytral interstices less 

 evenly convex, &c., &c.,; compared with C. acervata, Germ., (which 

 is supposed to be identical with mnea, Boisd.) it presents similar 

 antennal differences, its prothorax differs by the concavity of its 

 front margin, the much greater closeness and evenness of its 

 coarser system of puncturation, &c., &c., and the elytra by the con- 

 vexity of their interstices. Two species have been previously 

 recorded from Queensland, — C. marynorata, Baly, which has 

 yellowish elytra sprinkled with piceous patches, — and C. rufipes, 

 Jac, which has the prothorax very sparingly punctulate, besides 

 colour differences. 



Taken near Brisbane by Mr. Hurst ; several specimens. 



N.B. — Specimens taken in the Adelaide district, also on Yorke's 

 Peninsula and near P. Lincoln, appear conspecific with this, 

 although the brassy tinge of colour on their upper surface is more 

 decided and they seem te be a little more convex longitudinally, — 

 the elytra viewed from the side presenting an upper outline which 

 forms a more decided curve; in some of these examples, more- 

 over, the elytra are more or less opaque and finely coriaceous, — 



the latter character being possibly sexual.
