858 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



four round smooth fovere placed transversely across the disc a little 

 iu front of the middle. The scutellum is impuuctate. The elytra! 

 costae are all very faint, the external one scarcely discernible (in 

 ray example it is quite lost on one elytron, nearly so on the other). 

 On the underside the following i)arts are clothed with long but not 

 close pubescence, — the mentum, the front of the prosterniTm, the 

 reflexed margins of the pronotum, the ])rosternal process, the 

 lateral portions of the meso- and meta-sterna, and a line across 

 each ventral segment. All the above pubescence is erect except 

 that at the front of the prosternum, which is directed forward, but 

 with a tuft in the middle erect. The legs, the basal two joints of 

 the antennae, and also the ocular canthus are clothed with long 

 hairs. 



A single specimen (apparently a female) was sent to me from 

 Palmerston, N. Territory, by Dr. Bovill. 



Cacociiroa obscura, sp.nov. 



Minus convcxa; nigia; supra glabra ; pygidio, corpore subtus, 

 et pedibus plus minus ferrugineo-hirsutis ; clypeo sat fortiter 

 punctulato, antice sat fortiter emarginato ; prothorace sparsim 

 obscure (lateribus sat fortiter) punctulato, angulis posticis 

 rotundatis ; elytrorum disco fortius sublineatim punctulato, 

 lateribus crasse transversira rugatis ; tibiis anticis 3-dentatis.

The head closely resembles that of Cacochroa gymnopleura, but 

 is more closely punctured in the hinder part. The prothorax is 

 gently lobed in the middle behind, and is not much less than 

 twice as wide at the base as it is long down the middle, its front 

 margin being less than half as wide as its base ; its hind angles 

 are quite rounded off; its surface is very sparingly and finely 

 punctulate, except near the front margin (where the puncturation 

 la rather stronger and closer) and near the sides (where it is very 

 strong and coarse) ; the lateral furrow (within the thickened 

 margin) does not reach the base, but ceases where the side begins 

 to round off to the hind margin. The scutellum is elongate, with
