3G8 MISCELLANEA ENTOMOLOGICA, 



margin. The legs are slender and rather long. The fore thighs 

 and tibijB are a little curved inwards, the latter is not enlarged 

 towards the apex, has the emargination on the inner surface small 

 and very near the apex, and has the terminal spine on the inner 

 side large, acute and curved. The intermediate thighs are armed 

 on the under side not far from the apex with a large strong 

 slightly curved spur. The trochanters of the hind legs are large, 

 straight, and bluntly acuminate. The four first joints of the fore 

 tarsi in the male are rather broader than in the female. The 

 prosterum is flat and* broad, and is extended backwards in a 

 broad laminated and somewhat recurved form, as if by its contact 

 with the mesosternum it was intended to prevent the long heavy 

 head and thorax of the insect from drooping too much. 



I received, a few months ago, from the Richmond River dis- 

 trict, a Feronia of sculpture of a most peculiar and unusual kind. 

 It differs in one way or another from all the subgenera given by 

 Baron de Chaudoir in his " Essai sur les Feroniens de 1' Aus- 

 tralia," and it does not quite fit into any of the very many sub- 

 divisions of the group. Ahax seems to be the one to which it 

 most approximates, I shall accordingly call the insect 



Abax sulcipennis. 

 Long. 9 1 lin. 



Brunneo-cupreus nitidus subplanus, capite profunde bisulcato, 



thorace subtransverso medio profunde canaliculato postice

If the work so ably commenced by Baron de Chaudoir 



of arranging and classifying the Australian Feronidce, should 



ever be brought to a completion, this insect will, I have no doubt,
