segments narrow, the last two and first six abdominal segments 

 on their upper side ornamented with an irregular oval warty 

 patch, widest and roundest on the apical ones ; last segments 

 smooth, anal segment overlapped by preceding one. 



The larva has a preference for dead or dying bushes of Acacia 

 longifolia, forming large parallel chambers, never of any great 

 length, in the sap-wood of the larger stems. 



I have never found the beetle on Acacias, though I have cut a 

 number out of their stems ; but I have taken it on the foliage of 

 Kunzea, and hiding on the stems of Banksias at Rose Bay in 

 January. It is a large handsome dark brown beetle, with the 

 first two joints of the antennae very stout and thickened, the 

 thorax very much wrinkled, and the elytra and legs covered with 

 a white silvery pubescence.

 t. 23, f. 10. 



Larva stout, thick, white, covered lightly with short hairs ; 

 mouth parts and jaws black, latter broad and stout, head broad 

 and square, flat in front, lobed on either side by a line running 

 down towards the mouth, base of head smooth and shining, the 

 upper portion rugose, with a furrow in the centre of forehead ; 

 legs small, thoracic and abdominal segments with a deep elongate 

 transverse depression in the centre of each segment, with corre- 

 sponding ones on the under side ; anal segment long, slender, 

 smooth, shining, rounded at tip. 



The larva attacks the stems of Kunzea corifolia, which it 

 traverses in every direction ; commencing under the bark, it 

 gnaws irregular passages backwards and forwards, finally making 

 several large parallel chambers towards the centre of the stem, in 

 one of which it pupates. 



The beetle is to be found, together with many others, feeding 

 upon the honey in the flowers of the small scrub Angophora (A. 

 cordifolia) in the end of December, but I have also taken them 

 on the foliage of the food plant. The sexes are very unlike each 

 other, the male black with white markings on the thorax and
