with fine long hairs ; the antennae having the first joint very stout, 

 all the joints fringed on both sides with long black hairs, the third 

 joint being further ornamented at its apex with a little black ball 

 composed of fine hairs. 



Bred out early in October from branches obtained at Rose Bay.

The larva bores narrow irregular chambers along the centre of 

 the smaller branches of the dead wood of Acacia decurrens. Two

 legs, and thorax ferruginous-brown ; the head long, eyes very 

 prominent ; thorax cylindrical, rather narrow at base, swelling 

 out and slightly ribbed above the apex, which is constricted at 

 the junction with abdomen ; elytra long, slender, of a uniform 

 thickness, rounded at the tip, pale ferruginous-brown, with six 

 pale white parallel ribbed lines running from the shoulders to the 

 tips of the wing covers.

For some weeks, during the months of July and August, I
