basalibus abdominis longitudinaliter late excavatis ; eoxis anticis 

 approximatis ; femoribus subpedunciilatis. Long. 2 lin. 



Hab. Melbourne. 



I have adopted M. Jekel's catalogue name for this little 

 species, the only one, I believe, hitherto found in Australia.

Hab. Natal. 



This species has the normal head of Cordus and the broad 

 irregular rostrum of Amoryhocepkalus, and is therefore inter- 

 mediate in these respects between the two genera ; but as the 

 former character apppears to be of the most importance, it is 

 referred to Cordus ; it may, however, be desirable eventually 

 to separate it generically. 



A morjjJioce^yhalus sulcicollis. 



A. {S) nitide ferrugineus ; capite brevi, postice vix truncato, inter 

 oculos verticeque profunde triangulariter excavate, fundo excava- 

 tionis leviter sulcato ; oculis ampliatis ; rostro supra paulo arcuate, 

 longitudinaliter fortiter excavato, basi utrinque oblique constricto

 culis secundo usque octavum valde transversis, none et decimo 

 longioribus, perfoliatis, ultimo conico ; prothorace oblongo, basi 

 quam apice parum latiore, in medio fortiter canaliculate ; elytris 

 prothorace in medio vix latioribus, striatis, interstitiis convexis 

 subtilissimo sparse punctulatis ; tibiis intus bisinuatis, apice spina 

 conica instructis. Long. 5 lin. 



Hab. West Australia. 



The canaliculate prothorax is an exceptional character in 

 the subfamily to which AmorjyTioce^Tialus belongs ; but it oc- 

 curs in the genus Trachelizus^ the representative of the group. 

 I have two other specimens of Amorj)hoce])Tialus from West 

 Australia, one of which may possibly be the female of the 

 above (see fig. 9, «, the head), the other (see fig. 9, J, the
