490 NOTES ON AUSTRALIAN COLEOPTERA, 



clypeus and labrum being very similar. The following seem to be 

 the points of difference from H. nasutus ; clypeal suture not 

 angulated, prothorax a little less transverse (about once and § as 

 wide as long) and more narrowed anteriorly, hind coxae very much 

 shorter (nearly as short as the 2nd ventral segment), hind body 

 (not " finely coriaceous " but) very nitid, basal piece of hind tarsi 

 (not " exceptionally strongly " but) not in the least prominent at 

 the apex. 



In the tabulation of the sub-group of Heteronyx to which this 

 species belongs (P.L.S.N.S.W., 1889) it falls under «GG" (near 

 the end of p. 143) along with H. auricomus, Blackb., from which 

 its clypeal suture not angular in the middle and the more sparse 

 puncturation of its prothorax will, inter alia, distinguish it. The 

 rather strong anterior narrowing of the prothorax approximates 

 it to the species under " FF " (anceps, tfcc.) ; all those, however, 

 have the labrum and clypeus quite differently related to each 

 other except Sloanei, Blackb., in which these parts are a little 

 (but not very much) similar, but in that species the prothorax is 

 much more closely punctured.
