long reddish hairs ; abdominal segments slightly rounded on the 

 sides, smaller and more rounded towards the apex. 



The larvte feed upon the dead wood of various species of 

 Eucalypts, living chiefly oa the sapwood, which is completely- 

 riddled with irregular parallel channels which often cross and 

 run into each other, and are all filled in behind as the insect 

 moves along. When full grown it pupates in a small oval 

 chamber at the end of its bore. The beetles as soon as they 

 emerge bore circular shafts straight through the bark into the 

 sapwood, laying an egg at the bottom. The bark of a large dead 

 Eucalypt (probably E, hoemastoma) was covered with these little 

 pits, out of which streams of fine dust were falling; beneath was the 

 sapwood containing larvae and pupse in all stages of development. 



The perfect beetle is 2| lines long ; head ferruginous, very 

 rugose, slightly furrowed on the sides, jaws black ; thorax pale 

 ochreous-yellow, projecting on either side of the head ; a small 

 curved hook standing out in front above the forehead; the frontal 

 portion of thorax covered with short warty black spines, the 

 apical part finely punctured, shiuiiig ; legs ferruginous ; elytra 

 black, slightly rugose, covered with small punctures, apex truncate, 

 sloping down to the anal tip, the elytron produced into two short 

 spines at the apex, the tips of which are split into two fine points. 



Hah. — Hornsby. In the log from which I obtained these 

 beetles I found a number of long slender larvae which appeared to 

 be parasitic upon the beetle larvae, but I was unable to breed them.

Larva a short, stout, dull brownish-green grub, the mouth parts 

 small, and hidden by the folds of the first thoracic segment, 

 which is produced on the dorsal side into four stout tubercles ; 

 the following nine segments, each forming a double fold, the first 

 small, wedge-shaped, with a projecting point at either side, the 

 second fold carrying a row of eight finger-like points, the four 

 central ones longest, the last segment overlapping the anal tip ; 

 legless, and smooth on the ventral surface. The larva exudes a 

 slimy secretion, with which it is covered on the upper surface.
