36 ON THE LIFE-HISTOPIES OF AUSTRALIAN COLEOPTERA, 



showing the tarsal joints, covered with short reddish hairs; mouth 

 parts ferruginous, jaws black, large, and pointed; antennae long, 

 five-jointed ; head dull yellow, smooth and shining; first thoracic 

 segment small, others uniform with the abdominal ones, on the 

 upper side each is divided into three distinct ridges, each with a 

 transverse row of reddish hairs, last two segments not furrowed, 

 smooth and shining, covered with fine short spines or short hairs 

 as well as the longer scattered ones, last segment rounded. 



The larva lives in rotten wood, either the debris in a decaying 

 tree or in similar matter in a cleft, The specimens bred were 

 taken out of a cavity between the limbs of a Eucalypt at St. 

 Mary's, N.S.W., last July; and three months later when examined 

 were all enclosed in hard oval earthen cocoons covered over with 

 dirt and excreta. 



This is one of our commonest Cetonias, and is very plentiful in 

 the neighbourhood of Sydney towards the end of Dece)nber, when 

 numbers of them can be taken on the flowers of the stunted 

 Angophora (A. cordifolia). The pale yellowish-green markings 

 on the deep chocolate-coloured body, which is almost black at the 

 head and apical portion of the elytra, give this beetle a very 

 showy appearance.

Larva slender, pale yellow, with small head and regular seg- 

 ments ; mouth parts pale ferruginous, jaws black, very small ; 

 head long, triangular in front, raised in the centre, with two 

 parallel ferruginous lines coming from the apex and converging 

 into a point on forehead, on the under side of head a single 

 straight line ; thoracic and abdominal segments regular, slender 

 and tapering to the anal one, which is slightly pointed. 



The larva feeds upon the stems of Acacia junij^erina, hollowing 

 out the whole of the wood of the slender stems of this scrubby 

 bush . 



The specimens bred were obtained from bushes growing on 

 the ranges near Bendigo, Victoria : it is also a common Sydney
