with a patch of small punctures in centre ; thoracic and abdominal 

 segments of uniform size, deeply divided, rounded, with an elon- 

 gate-oval depression, rugose on the inner edges in the centre of 

 each, with corresponding markings on the under side, last segment 

 smooth and cylindrical, overlapping the anal tip. 



The larva feeds upon the soft woody stems of Viminaria 

 deniidata, eating the centre out of the small branches, and 

 pupating in the tips. I have also bred it from the small twigs of 

 Acacia longifolia. 



The beetle feeds upon the young shoots of Vi7)iinaria dcmtdatay 

 and girdles or ring-barks the branch by gnawing several broad 

 irregular bands round it, IsCying its eggs, one at a time, in small 

 holes gnawed in the bark above the girdles, and generally deposit- 

 ing three or four in each branch. It is somewhat about the same 

 size as S. nigrovirens, with a similar broad white stripe on either 

 side of the elytra, but the back is of a uniform reddish-brown, 

 marbled with irregular wavy buff markings. Found in N. S. 

 Wales and Queensland. 



Symphyletes neglectus, Pascoe, Trans. Ent. Soc. 1863, p. 534. 



Larva dirty white, slender, with rounded regular segments ; 

 mouth parts ferruginous, jaws black, head broad, angular, smooth 

 and shining, with a few shallow scattered punctures across the 

 centre, a short parallel line on either side, causing the centre of 

 head to appear square ; second and third thoracic, and all the 

 abdominal segments except the last two, marked on the upjDer 

 side with a wrinkled elongate-oval patch in the centre, with 

 corresponding but more slender marks on the under side, last 

 abdominal segment almost covering the anal extremity. 



The larva feeds upon the stems of Acacia longifolia, eating out 

 the wood in irregular tunnels, and pupating in the end of the last 

 one. 



The beetle is plentiful in December about Botany and Rose 

 Bay ; it girdles or ring-barks each branch with three or four deep 

 rings right through the bark, then crawls up and gnaws several 

 circular little flaps of bark in a horse-shoe shape without detaching
