of the Scaritidae, and Delinius Essingtoni a very curious form of 

 the Feronidae described by Westwood in the Proceedings of the 

 Entomological Society of London for 1&64, p. 3. 



The following appear to me to be new : — 



Carenum Darwiniense. 



This species belongs to the group of which G. Spencei is the 

 type — a group now so numerous that it may well be formed into 

 a separate genus, characterized by short moniliform antennae, 

 slightly securiform palpi, tridentate anterior tibiae, and foveated 

 elytra. This last character is so strongly marked in all of the 

 species that I would suggest for the genus the name ofLaccopterum. 



I have only one specimen ; it is seven lines long, of a subnitid 

 coppery red on the elytra, thorax, and back part of the head, 

 metallic green on the epi pleurae, and black everywhere else. The 

 head is broad and flat, and the facial grooves are deep and curved 

 outwards both before and behind. The thorax is a little broader 

 than the head, and is broader than long, with the posterior angles 

 rounded, and a short broad recurved lobe in the middle of the 

 base ; the median line and the depression near each posterior 

 angle are well marked. The elytra are moderately convex and 

 slightly narrower than the thorax, with seven punctured striae on 

 each elytron, and large foveae on four alternate interstices, these 

 foveae are most numerous in the sutural, and least so in the fourth 

 row, the other interstices are narrower and subcostate. There is 

 a dense row of punctures on the lateral margin, and the epipleura, 

 which is deep, is roughly punctured. The legs are moderately 

 robust, and there are three teeth on the outside of the anterior 

 tibiae, the upper one small. 



When I first saw this insect I fancied it might be the 

 G. Gemmatum of Westwood, a species I had never seen, but 

 which, like G. Sumjpiuosum, had been described as coming from 

 Port Essington. I find, however, that beyond belonging to the 

 same group there is little similarity between them. 



Carenidium Spaldingii. 



Fourteen lines long and of convex form. The head in front, the 

 disk of the thorax, and a large patch in the centre of the elytra
