the centre of the thorax, and a broad shield-like patch of a similar 

 colour from the shoulders down to the centre of the elytra, giving 

 it a handsome marbled appearance.

A good number of .specimens of this longicorn were bred from 

 infested twigs taken from a dead tree of Acacia decurrens at 

 Carlingford ; the first appeared about the end of August, others 

 following until the middle of November. The larva feeds upon 

 the young branchlets. 



The beetle is 5^ lines long, of a uniform reddish-brown, jaws 

 long and curved, head slender, thorax long and cylindrical, elytra 

 shining, rounded at the tip, the whole insect covered with a coat 

 of stout white hairs. 



Stephanops nasuta, Newman, Entomological Mag. Vol. v. p. 510. 



This is a very long slender longicorn, with the fore part of the 

 head greatly produced, the eyes very prominent, aud tlie antennae 

 light reddish-brown, long and slender. It is 7 lines in length, but 

 not much more than a line across the widest part of the shoulders; 

 head and thorax dark ferruginous-brown, the apex rounded and 

 cylindrical ; legs reddish-brown, long and slender, the apical 

 portion of the femora thickened; the elytra reddish-brown, covered 

 with a fine grey pubescence, with the outer edges bare and shining, 

 forming a narrow line round the margins. 



Two specimens were bred from stems of Acacia longifolia 

 obtained at Rose Bay in the end of November. 



Pentacosmia scoparia, Newman, Entomologist, 1842, p. 361. 



The larva of this beetle, which feeds under the bark, is hardly 

 noticeable in a large twig ; several came out in a show-case from 

 mounted specimens of Acacia longifolia some months after they 

 had been placed therein. 



The beetle is 3 lines in length, dark brown, clothed with 

 greyish-buff pubescence; the head, thorax, elytra, and legs fringed
