356 NOTES ON AUSTRALIAN COLEOPTERA, 



(vix arcuatim) angustato ; elytris sat fortiter punctulato 

 striatis, iuterstitiis sat planatis. [Long. 11, lat; | line. 



The basal ventral segment bears a semi-circular impression 

 which is continued feebly on the 2nd segment. The 5th ventral 

 segment is notfoveated in either sex, but in the sex with the longer 

 rostrum it is emarginate on its hind margin, with what appears to 

 be a minute additional segment beyond. 



PHYTOPHAGA. 



Chalcomela sloanei, sp.nov. 



Rotundata ; valde convexa ; nitida ; subtus nigra ; supra 



picea, viridi et purpureo obscure micans, antennis palpis 



pedibusque rutis ; elytris sat fortiter punctulato striatis, 



interstitiis sub-convexis. [Long. 3, lat. 2| lines. 



The head is impunctate or nearly so ; it bears a very deep 



transverse angulated furrow dividing the cly pens from the forehead 



and a feebler longitudinal furrow running down the forehead. 



The prothorax is nearly three times as wide at the base as it is 



long down the middle ; it is narrowed and gently rounded from 



the base to the front, very minutely punctulate and also bearing 



a number of larger (but still small) punctures which become a little 



more numerous and coarse towards the sides than in the middle. 



The elytra are strongly seriate-punctulate, the rows of punctures 



in shallow strise between which the interstices are gently convex, 



each of them bearing a row of small distantly-spaced punctures. 



The green and coppery reflections on the upper surface are not 



very conspicuous and do not seem to form any defined pattern ; 



the suture and apical region are the brightest parts but almost 



any part can be made to appear more or less green or coppery from 



some point of view. 



The entirely red antennae combined with general obscurity of 

 appearance, absence of coloured pattern, and convexity of elytral 

 interstices will readily distinguish this species from all its pre- 

 viously described congeners.
