BY THE REV. T. BLACKBURN. 1221 



In the tabulation of the 1st section of Heteronyx (Proc. L.S. 



N.S.W. 1888, pp. 1328, &c.) this species would fall under " C' 

 (line 3, p. 1329), its companions under that letter hfting fulvo- 

 hirtus and hadius ; the hind claws of the former of these are 

 appendiculate (the produced apex of the basal piece being very- 

 much smaller than the apical piece), while the latter is an 

 infinitely more closely punctulate insect than H. Bovilli. 



N. Territory of S. Australia ; taken by Dr. Bovill. 



H. ADVENA, sp.nOV. 



Minus elongatus ; postice vix dilatatus ; f errugineus, anten- 

 narum clava testacea ; pilis minus brevibus adpressis minus 

 sparsim vestitus ; sat fortiter (postice gradatim minus fortiter) 

 punctulatus ; labro clypeum baud superanti ; antennis 8-articu- 

 latis ; coxis posticis metasterno vix brevioribus ; unguiculis 

 bifidis ; segmentis ventralibus apicalibus vix perspicue punctulatis.

The description of the head of H. Bovilli will apply to this 

 species, subject to the remark that the clypeus is not at all 

 emarginate in front. The description of the prothorax (dis- 

 regarding puncturation) will apply moreover, except that in this 

 species the sides are a little more arched and the hind angles are 

 quite rounded off. The transverse wrinkling of the elytra is 

 little noticeable, their lateral fringe normal, their apical mem- 

 brane obscure. The puncturation of the head is coarse, strongs 

 and rather close, — that of the prothorax and elytra successively 

 feebler, that of the pygidium quite obsolete ; the punctures 

 on the prothorax are spaced so that about 14 or 15 of average 

 distance apart would run in a line down the middle. There is 

 some indication in this species of a sutural stria and the suture 

 is slightly elevated, while in //. Bovilli the suture is non-striate 

 and flat. The proportions of the various parts on the underside 

 are almost as described above (vide H. Bovilli), but the hind 

 coxse are a little longer. The puncturation of the metasternum
