season, while little streams of dust could be seen falling from the 
holes where they had gnawed through the bark; most of the 
fallen branches are hollowed out before they break off, but the 
larva nearly always remains behind in the stump of the branch 
feeding into the green wood, which dies down below where it 
pupates. They take some time to reach maturity, certainly not 
before the second year, as I have kept larvae over that time 
without any sign of their pupating. 
Mr. Geo. Masters tells me that at Elizabeth Bay, Symphyletes 
nigro-virens feeds upon the garden Pittosporums; while Strongy- 
lurus thoracicus confines its attacks to the white cedar LMelia 
composita), cutting off the branches in exactly the same manner. 
The beetle is 10 lines in length, with dark brown head clothed 
with coarse brown hairs, an elongate spot of silvery white hairs 
between the eyes; antennae toothed on the outer apical margin of 
each joint; thorax dark reddish-brown, deeply and coarsely 
punctured, with three large round patches of white hairs on 
either side, with another smaller one in front of the scutellum; 
etytra ferruginous on the shoulders, paler towards the tips, deeply 
punctured for about two-thirds of their length, but almost smooth 
towards the apex; a row of -4 small black spots across the 
shoulders, with an irregular black horseshoe-like band on either 
side; the tips of the wing covers and the apical margins black; 
the whole of the upper surface clothed with scattered grey down; 
underside clothed with greyish hairs, with a patch of white hairs 
forming an oval mark on the side of each segment. 
The larvas were most active in the early summer months after 
the new year, the beetles breeding out early in December. 
Aterpus cultratus, Fabr. 
Larva 5 lines in length, short, and obese, lying with its back 
arched and the tip of the abdomen curved towards the head; dull 
white, with dark chocolate-brown head, truncate at the base, 
mouth parts rather prominent, and with a median groove lightly 
impressed down the centre of the head; a dark brown transverse 
line in front of the first thoracic segment; on the dorsal surface
