I find that in 1883 a M. Doukhtouroff published at St. Peters- 

 burgh in a production of his own, named " Revue Mensurelle 

 d'Entomologie," descriptions of two species of this genus said to be 

 from Cape York, Those I have now described may possibly, 

 though not probably, be identical with M. Doukhtourofl^'s species, 

 but that cannot be determined without seeing his descriptions, 

 and they are inacessible to Australians. If M. Doukhtouroff had 

 published his descriptions of Australian Insects in any of the 

 Scientific Societies' Journals of St. Petersburgh or Moscow, as was 

 done by his countrymen Baron de Chaudoir and Motschulsky, there 

 would have been no difficulty in getting access to them, but as he 

 has chosen as his vehicle of publicity an entirely unknown and 

 unprocurable book, he must not feel aggrieved if his work is 

 altogether ignored by Australian Entomologists. 



CARABID^. 



5. Helluosoma viridipenne. 



Piceous-black, nitid, elytra metallic-green, tarsi beneath piceous- 

 hairy. Head thinly punctate, the clypeus and labrum smooth. 

 Tliorax rather broader than the head, transverse, cordiform, 

 coarsely punctate, deeply impressed near the posterior angles, the 

 base truncate. Elytra broader than the thorax and three times 

 the length, punctate striate, the interstices broad, nearly flat, and 

 rather rugosely but not densely punctate. The legs and all the 

 upper surface of the insect clothed with a thin whitish pubescence. 



Length, 9 lines. 



Hah. — Cairns. 



The nearest species to this is //. cyanipenne of Hope. It difiers 

 from it in having broader elytra, a less dense but coarser punc- 

 tu ration, and in the colour of the elytra which is bright metallic 

 green.
