retldish-yellow scales which form a slightly ocellated pattern 

 u[)on the thorax, becoming more undefined on the elytra. 



In the male the jaws are large, curved inwards, broad, and 

 toothed at the tip, with a square wing or flange on the outer side 

 i n front of the eyes. 



Though this pretty little staghorn is plentiful in the bark of the 

 Eucalypt I'eferred to, Mr. Blackburn says it is new ; I have never 

 found it at Jaige. 



DiAPHONiA DORSALis, Don., Insects of New Holland, t. l. f. 1. 



Larva a large bluish-white grub about 19 lines in length and 6 

 lines in diameter, rounded on the dorsal side, with the marginal 

 fold, and spiracles very jirominent ; jaws three-toothed, stout and 

 black ; the antennje five-jointed, basal ones pale, apical ferruginous; 

 the forehead rugose, bisected in centre forming a broad triangle 

 towards the jaws, with an angular ferruginous patch on either 

 side of the first thoracic segment ; legs long, covered with fine 

 reddish hairs ; all the thoracic and abdominal segments trans- 

 versely ridged with three deep furrows which all converge and 

 merge into the centre of the marginal fold, anal segment obtusely 

 rounded ; the whole insect covered with fine short reddish hairs, 

 interspersed with a few longer ones on the sides of the head and 

 thorax. 



The larvae were very plentiful towards the end of last March 

 under large logs between Carlingford and Eastwood ; they are 

 usually just covered with earth mould. 



I kept some thirty specimens in a large tin full of damp earth, 

 and though several formed cocoons, with one exception they were 

 all infested with dipterous larvae which after a time broke holes 

 through the sides of the earthy cocoons and came out. 



On the 1st December I examined the remaining cocoons and 

 found the only perfect one contained a dead but perfect beetle. 



The beetle is one of the largest Cetonias found near Sydney, 

 and though not as common on the flowers of Angophora cordifolia 

 as some of the other species, it is often found flying about in the 

 street, or buzzing in at open windows during the summer months.
