1264 NOTES ON AUSTRALIAN COLEOPTERA, 



Adelaide. It agrees very well with Erichson's description, and is 

 certainly not a Rhizopertha but may well stand in Apate^ where 

 its author placed it. An example taken by Mr. J. Anderson at 

 Port Lincoln, is narrower and more elongate than that just 

 referred to ; I take this difference to be sexual ; the elytra more- 

 over are not rufescent at the base as in Erichson's description 

 and the Adelaide specimen. In both these I find the slightest 

 possible indication in some lights of two or three costse (not 

 mentioned by Erichson) running down the elytra. 



Xylopertha mystica, sp.nov. 



(J. Elongata ; cylindrica ; sat nitida ; glabra ; picea, anteunis 

 palpis tarsisque testaceis, femoribus tibiisque rufescentibus ; capite 

 sat elongato, longitudinaliter sat crebre strigato, antennis pro- 

 thorace vix brevioribus ; prothorace elytrorum latitudine, quam 

 latiori fere longiori, antice sat angustato, postice subtilius sparsim 

 conspicue punctulato, antice crebre granulato-ruguloso tuberculis 

 nonnullis majoribus intermixtis (praecipue latera versus), utrinque 

 unco supra oculum hand armato ; elytris crebrius fortius vix 

 rugulose (apicem versus vix magis fortiter) punctulatis, postice 

 minus abrupte declivibus, apice singulatim valde productis et intus 

 acute angustatis, parte declivi ad latera carinata et utrinque 

 concava, sutura antice plana in parte declivi sat fortiter carinata, 

 apice minute spinoso-producta, humeris laevibus ; tarsis posteriori- 

 bus 4 gracilibus compressis, supra visis fere capilliformibus, tarsis 

 anticis perlonge j^ilosis ; tibiis anticis subtus minute denticulatis.

The non-declivous portion of the elytra is quite twice as long as 

 the declivous part. The denticulations under the front tibiae are 

 scarcely noticeable without the aid of a compound microscope. 



In company with the specimen described, I found an 

 example which I have no doubt was the female of the same 

 species, but unfortunately I broke it to pieces in trying to 

 examine its mouth organs. It differed from the male in being a 

 much shorter and wider insect with the front tarsi not pilose, and
