Hub. Richmond liivev. 



A dull-coloured species, which in the smaller facets of the 

 eyes resembles 0. hilij>oides, a species which in momentary 

 aberration I described as an Alcides'^ in the sculpture of the 

 -elytra it is unlike any of its congeners. This and the fol- 

 lowing species have no fasciculi. 



Orthorhinus carinatus, 

 O. oblongo-ovatus, fuscus, sordide griseo-squamosus ; rostro brevi- 

 usculo, rude punctato, parce elongato-squamoso ; antennis sub- 

 testaceis, squamis jjiliformibus vestitis ; funiculo articulo primo 

 elongato ; prothorace subtransverso, quarta parte anteriore mani- 

 feste constricta ; elytris sat fortiter convexis, apicem versus parum 

 latioribus, substriato-punctatis, interstitiis alternis tuberculato- 

 earinatis, carina interiore ante apicem cvanescente, secunda pos- 

 tice paulo prominula, basi plaga umbrina, margine postico arcuata 

 et bene limitata notatis, sed aliquando fere obsoleta ; tibiis, pra)- 

 -sertim anticis intermediisque, brevibus, iUis valde compressis. 

 Long. 3|-4 lin.

The outline and well-marked carinaj on the elytra are the 

 principal diagnostic characters of this species. 



As I have to propose several new genera of Erirhininie, the 

 following table will be useful in showing their more prominent 

 diagnostic characters ; and it includes, I believe, all the Aus- 

 tralian genera yet published. There will still remain, however, 

 several unnamed species in collections to be examined. The 

 subfamily is apparently a very numerous one in Australia, and, 

 from the exceeding variability of its characters, a very difficult 

 one to classify. The two Xew-Zealand genera [llo^yJocneme 

 and Stephanorliynchus) are widely removed from all known 

 Australian forms *. I think that in ]\lr. Wallace's Malayan 



* A third geims, JBur/iiomus (Schouli. Mant. Soc. p. 45), is said to be from 

 Now Zealand ; but no species has been described.
