Orthorliinus infidus. 



O, angaste ovatus, piceus, squamis silaceis elongatis vel setiformibus 

 sat vage vestitus ; rostro modice elongate, crebre punetato ; oculis 

 subgrosse granulatis^ antennis subfcrrugineis ; funiculo longius- 

 culo, articulo primo elongate ; protliorace subtransverso, lateribus 

 pone apiceBi fortiter rotundato, confcrtim granulato-punctato, 

 squamis setiformibus vestito, in medio, apice excepto, carinato ; 

 •elytris modice convexis,sulcato-punctatis, puiictis leviter impressis, 

 interstitiis convexis, granulis transversis concoloribus rude in- 

 structis, scjuamis elongatis, postice magis condeusatis, conspersis ; 

 tibiis posticis prope apicem fortiter compressis. Long. 6 lin. 



Hub. Richmond River. 



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

 "eyes resembles 0. hilipoides^ a species which in momentary 

 aberration 1 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. 



Orthorh inus carinutas. 



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

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

 testaceis, squamis piliformibus vestitis ; funiculo articulo primo 

 elongate ; prothorace subtransverso, (jiiarta parte anteriore mani- 

 feste constricta ; elytris sat fortiter oonvexis, apicem versus parum 

 latioribus, substriato-punctatis, interstitiis alternis tuberculato- 

 ■carinatis, carina interiore ante apicem evanescente, secunda pos- 

 tice paulo prominula, basi plaga umbrina, margiue postice arcuata 

 ■et bene limitata netatis, sed aliquando fere obsoleta ; tibiis, prae- 

 sertim anticis intermediisque, brcvibus, illis valde compressis. 

 Long. 3|-4 lin.

The outline and well-marked carinas on the elytra ai-e the 

 principal diagnostic characters of this species. 



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

 following table will be useful in showing their more prominent 

 diagnostic characters ; and it includes, 1 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, Tlie two New-Zealand genera {Hoplocneme 

 and IStephanorhynchus) are widely removed from all known 

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



* A third <xtmusi, Etir/iioiitu^ (Sobouh. Muut. Sec. p. 4e), is said to be from 

 New Zealand ; but uo species has been described.
