maxilla, and maxillary palpi, however, are exactly those o£ 

 JN'. Qiiger, while the apical joint of the labial palpi is distinctly 

 shorter and more ovate, the legs (as in N. niger) are those of 

 a Cavonus. The antennae (as in N. niger) are ten- jointed ; their 

 club is not very wide, and in length scarcely exceeds the rest 

 of the joints taken together. The shape of the clypeus is very 

 different from that of Cavonus and Neocavonus, but there is 

 sufficient clypeal variation among species that seem otherwise 

 inseparable from Cavonus to render it prudent at present to 

 make as few genera as possible until the structural characters 

 of more species have been recorded. At a first glance this in- 

 sect is distinctly suggestive of male Isodon, from which the 

 elongate subcylindric basal joint of its hind tarsi, its totally- 

 different clypeus, the elongate club of its antennae, and the 

 complete dissimilarity of its maxillse, of course, separate it 

 very widely. 



I possess a single specimen taken by Professor Tate at 

 Eowler's Bay. 



COETNOPHTLLUS. 



G. Andersoni, sp. no v. Convexus ; nitidus ; castaneus ; capita 

 prothoraceque nigro-piceis ; subtus dense fulvo-pubescens ; 

 prothoracis lateribus subtus concavis ; elytris punctulato- 

 substriatis. Long. 81., lat. 4|1. (vix). 



Mas. Capite medio f ortiter transversim carinato ; prothorace 

 antice impresso, margine anteriori medio acute tuber- 

 culato. 



Fem. Latet. 



The clypeus appears to the eye scarcely transverse, but by 

 measurement it is decidedly so. Its outline viewed from the 

 front is a continuous curve, except at the base, which is 

 straight, and is raised gradually (from a little within its ex- 

 tremities on either side) into a keel which is somewhat less 

 elevated than the projection on the front of the thorax, and of 

 which the upper outline is sinuate. The head behind the 

 clypeus is flattened down the middle. The whole head is shal- 

 lowly and coarsely, but not closely, punctured. The pro thorax 

 is very finely and very sparingly punctured, the puncturation 

 more pronounced down the middle, and especially in the de- 

 pressed part. Its base is about half as wide again as its front 

 margin, its width quite twice its length down the centre. 

 Viewed from above, its sides (which diverge from the anterior 

 angles much more strongly than in any other of the genus 

 known to me) seem to form three curves, meeting each other 

 at roundedly obtuse angles ; viewed from the side the margin 

 appears to form from the base to the apex a strong even curve, 

 the convex side of which is the upper (not the lateral) outline
