all the Australian Oocles, as I see has been done already by Mr. 

 Masters in his catalogue of Australian Coleoptera. 



Sixteen species have hitherto been described from various 

 parts of this country, the majority of them from Western and 

 Central Austi'alia, but every portion of New Holland seems to be 

 represented by two or more species. With the exception of 

 G. Australls Dej. fuscitarsis Blanch., and ReicJiei Laferte, they have 

 all been described by Count Castelnau in his " Notes on Austra- 

 lian Coleoptera" published in Melbourne in 1867. 



My collection contains the following new species : — 



COPTOCARPUS ChAUDOIEI. 



Long. 5^ lin. 



Niger subnitidus latus, epistomi sutura semicirculari bipunc- 



tata, thorace leviter canaliculato utrinque oblique subim- 



presso, elytris tenuiter striatis stria scutellari brevissima 



interstitiis planis, antennis palpis pedibusque rufis. 



This species is from the Clarence River. It is of a broader 



form than G. Australis, and differs both from it and C . foiscitarsis 



in the extreme shortness of the scutellar stria, which is little 



more than an elongated point. 



CoPTOCARPDS Riverine. 

 Long. 7 lin. 



Niger subnitidus, thorace tenuiter canaliculato baud latera- 



liter impresso, elytris leviter striatis stria scutellari scu- 



tello ter longiori, antennis rufis articulis primis et tertiis 



subfuscis. 



In size and general appearance very like G. oblongus Casteln. 



It is however less opaque, and has the scutellar stria a little 



longer, and the hind tibise straighter than that insect. 



The insect from which I take my description is from the 

 Murrumbidgee, but I have two imperfect specimens in my col- 

 lection labelled " Interior S. Aust." which I believe to be of the 

 same species.
