I have some hesitation in referring this insect to Cholevomorpha 

 rather than founding a new genus for it. Unfortunately I have 

 not seen the male. I do not find in the female any good 

 structural character to distinguish it from C. picta — though it is 

 very different superficially, but not more so, I think, than are 

 some Cholevce from others. It agrees with C. picta in being of 

 decidedly Cholevid rather than Anisotomid type in general (in 

 respect e.g., of the antennte, metasternal epimera, style of 

 sculpture), but has hind trochanters of the Anisotomid type. Its 

 elytral suture is considerably raised (except near the base) as in 

 the previously described Cholevomorphce, but without the strong 

 subsutural stria that is found in them. It is inter alia multa 

 very different from them by the coarse, evenly distributed 

 puncturation of its upper surface which is not in the least seriate. 

 Its antennae are notably stouter than those of its described con- 

 geners, especially the first six joints, in consequence of which the 

 apical five joints form a much less conspicuous club. Its tarsi, too, 

 are distinctly shorter and stouter, and the fine spines on its tibiae* 

 are shorter, less fine, and less erect.

CLAMBUS. 



C. tropicus, sp. nov. Minus brevis ; postice angustatus ; nitidus ; 

 supra (exemplo typico observato) glaber ; obscure rufus, 

 antennis (clava inclusa) pedibusque (posticis haud observatis) 

 pallide testaceis ; elytris postice sparsissime minus subtiliter 

 punctulatis, stria subsuturali nulla. Long., § 1. (vix). 



I have not been able to examine the antennae and hind legs of 

 this minute insect sufficiently in detail to give a full description 

 of them, as I have only a single specimen. The upper surface is 

 practically glabrous, but under a microscope I find one or two 

 short erect setse close to the lateral margin of the elytra, which 

 perhaps indicate that the example before me is abraded ; a fresh 

 specimen certainly cannot have more than extremely scattered 

 setae. This species difi'ers from C. Tasmani, Blackb., and 

 C. tierensis, Blackb., in the absence of a subsutural elytral stria, 

 and from Simsoni, Blackb., by the very evidently more sparse 

 puncturation of its elytra.

This genus seems to be numerously represented in Australia, 

 The species as yet described stand under five names, none of 

 which are connected with descriptions sufficiently detailed to 

 allow of confident identification. The two descriptions of Sir W,
