158 REVISION OF THE GENUS EETEROiVYX, 



clypeum sat late sat fortiter superanti ; antennis 8-articulatis ; 

 tarsorum posticorum articulo basali secunclo vix breviori* ; ungui- 

 culis appendiculatis. [Long. 4f , lat. 2t lines (vix). 



This insect is so close to H. nigellns, Er., that it would be waste 

 of time and space to add to the above diagnosis more than a 

 statement of the respects in which the description of H. nigellus 

 would not agree with it. 1 distinguish it mainly by its testaceous 

 antennse, and the elongate basal joint of the posterior tarsi which 

 (from its actual root) is scarcely shorter than the second joint. I 

 observe also the following slight differences, viz., the colour in 

 general (possibly only an individual peculiarity except in respect 

 of the antennae, which in no species that I have seen vary with 

 the general colour of the surface), the wider and slighter sinuation 

 of the clypeus in front displaying a wider piece of the labrum, the 

 in general slightly closer puncturation of every part, the less 

 developed apical membrane of the elytra and the much feebler 

 uppermost tooth of the anterior tibiae. The hind coxae also are 

 less narrowed inwards from the external margin, and (in the 

 example before me) there is little or no pubescence on the pro- 

 thorax and elytra, — except of course the fringes. 



A single example was taken by Mr. J. G. O. Tepper, at Nor- 

 ton's Summit near Adelaide. 



H. AURICOMUS, sp.nov.

 ginous, antennis palpisque testaceis ; pilis aureo-brunneis sat
