1266 NOTES ON AUSTRALIAN COLEOPTERA, 



The example before me is clearly, I think, the female of a species 

 closely allied to the preceding. I am departing from my usual 

 practice in founding a description on the female only of an insect 

 that probably presents strong sexual characters, because the present 

 specimen is the only female I possess of this probably new genus, and 

 it is desirable that both sexes should be described. X, vidua differs 

 from X. mystica in the very much stronger and more rugulose 

 sculpture of the elytra (which appear coarsely shagreened rather 

 than punctured) and in the presence of a strong hooked spine on 

 either side of the front margin of the prothorax above the eye. 



The declivous portion of the elytra is nearly as long down the 

 suture as the non-declivous portion ; it is inclined at an angle of 

 about 45° to the non-declivous portion, and has a nearly flat or 

 slightly convex surface interrupted only by the carinated suture. 



S. Australia ; taken near Port Lincoln by beating branches of 

 trees. 



TENEBRIONID^. 



Pterohel^us raucus, sp.nov. 



Latus ; opacus ; niger ; quasi coagulatione tectus ; antennis 

 elongatis ; lateribus latissime deplanatis ; capite sub lente crebre 

 dupliciter punctulato, oculis sat approximatis ; prothorace quam 

 in medio longiori fere quater latiori, leviter insequali, medio longi- 

 tudinaliter canaliculato, disco crebre subtilius granulato ; elytris 

 granulatis, granulis hie illic majoribus in seriebus longitudinalibus 

 dispositis. [L^rig- 1^) ^^*- '^2 liiies. 



A remarkably fine and distinct species of the same group as 

 P. Walkeri, De Breme, which it resembles in shape, but the extra- 

 discal portion of the prothorax is concave (the lateral margins 

 being bent upward), and of the elytra wider (though much less 

 conspicuously separated from the disc owing to the granulation of 

 the latter being continued uninterruptedly almost to the actual 

 lateral margin). The antennae set back reach distinctly beyond
