mandibles ; eyes not prominent ; one supra-orbital puncture on 

 each side ; antennae light, tapering. Prothorax short, transverse 

 (4 x ~\ mm.), smooth, subconvex; anterior angles broadly advanced ; 

 sides subparallel, a little rounded towards front, shortly rounded 

 at posterior angles ; base shortly lobate ; marginal border broad 

 on sides, reflexed, very strongly reflexed at posterior angles, 

 thicker and less reflexed on basal lobe ; median line lightly 

 marked ; two marginal punctures on each side. Elytra ovate 

 (10 x 7 mm.), lsevigate, convex ; the suture deeply impressed ; 

 sides lightly and evenly rounded ; base truncate ; marginal border 

 broad, reflexed ; the marginal row of umbilical punctures evenly 

 placed and strongly marked ; each elytron with three punctures 

 in a single row on base, and a discoiclal puncture on apical third. 

 Anterior tibise tridentate; inferior ridge strong; apical plate with 

 a tooth projecting below the tarsi. 



Length 20, breadth 7 J mm. 



Hab. — W.A. (between York and Yilgarn). 



Of the species known to me this most resembles C. dispar, 

 Macl. ; but it differs conspicuously from that species in having the 

 prothorax broader and less convex, and more strongly lobate, the 

 elytra much less convex — especially towards the base — with the 

 suture much more deeply impressed ; the marginal border of both 

 prothorax and elytra is broader. 



The following notes contain information as to the synonymy 

 and distribution of some species of the Carenides which I have 

 accumulated during several years. I feel thoroughly satisfied of 

 the correctness of all the synonyms given, but in any case where 

 there may seem the least possibility of doubt I have stated such 

 to be the case. To make the list of localities as useful as possible, 

 while preserving conciseness and accuracy, I have added a key to 

 their positions on the map. In all localities given without any 

 authority being quoted I have myself collected specimens of the 

 species referred to in such localities, and I have stated my autho- 

 rity in every case except where I am personally responsible for 

 the locality.
