124 NOTES ON AUSTRALIAN COLEOPTERA, 



(AMYCTERIN^.) 



CUBICORHYNCHUS MUSSONI, Sp.nOV. 



Ovalis ; confertim piceo-squamosus ; piceo-niger, elytris ad 



latera et pedibus maculatira albido-squamosis ; nigro-setosus ; 



cristis in capite sat elongatis retrorsum inclinatis ; tuberculis 



frontalibus nnllis ; prothorace confertim granuloso ; elytris 



obscure punctulato-striatis, interstitiis planis alternis quam 



cetera paullo latioribus. [Long. 6, lat. 2§ lines. 



A somewhat longer and more oval species than most of its 



congeners ; this character, together with the black colour of its 



setae, the very close granulation of its prothorax, and the absence of 



frontal tubercles will distinguish it. The form of the crests on 



the head also is peculiar ; their external outline evenly continues 



bindward the external outline of the rostrum almost to the length 



of half the rostrum. Probably nearest to C. jnceo-setosus, Macl., 



which, however, is described as having its prothorax canaliculate 



down the middle and subtuberculate on the sides. This is the 



only Cubicorhynchus known to me in which the prothorax is not 



at all canaliculate.
