110 NOTES ON AUSTRALIAN COLEOPTERA, 



concave longitudinally. I do not notice any sexual distinctions 

 except that the antennal club seems a little elongated in the 

 examples I take to be males. 



Byrrhomorpha verres, sp.nov. 



Breviter ovalis ; valde convexa ; nitida ; fere glabra ; atra, 

 tarsis scutelloque vix rufescentibus, antennis palpisque rufo- 

 testaceis ; capite confettim crasse rugulose, prothorace con- 

 fertim rugulose minus crasse, elytris ciasse in^equaliter minus 

 crebre, pygidio subtiliter confertissime aspere, punctulatis ; 

 clypeo autice sat fortiter emarginato ad labrum recipiendum, 

 ante oculos leviter extrorsum dilatato ; prothorace quam 

 longiori (et postice quam antice) vix tertia parte latiori vix 

 manifesto canaliculate lateribus leviter arcuatis ; basi valde 

 retrorsum dilatata, margine antico fortiter arcuatim emar- 

 ginato, angulis anticis acutis fortiter productis, posticis 

 rotundato-obtusis (superne visis rectis et extrorsum subpro- 

 ductis) ; scutello magno antice punctulato; elytris insequaliter 

 sulcatis, interstitiis sat latis fortiter insequaliter transversim 

 rugulosis, alternis quam cetera irregulai'iter latioribus ; 

 tibiis anticis extus 3-dentatis, dentibus inferioribus magnis 

 acutis, tertio parvo ; coxis posticis quam segmentum ventrale 

 secundum vix longioribus ; corpore subtus pernitido fortiter 

 minus crebre punctulato. [Long. 5, lat. 3 lines (vix). 



Viewed from the side the labrum presents somewhat the 

 appearance of a small upturned horn or tusk. The sculpture of 

 the elytra is different from that of any of the allied genera. The 

 elytra cannot, I think, be regarded as genuinely geminate-striate, 

 and I should place the genus among those with the elytra simply 

 striate; but nevertheless tlie irregularity in width of the interstices 

 (which might be called uneven costse) brings some of the sulci 

 somewhat into pairs, — but this arrangement is rendered still 

 more irregular by some of the wider interstices being in places 

 split apart by uneven furrows that traverse them ; moreover the 

 distinctness of this arrangement varies in different examples.
