Orthorrhinus Klugi, Bohem., Schb. Gen. Cure. iii. p. 246, 



Larva semitransparent, with a brownish tinge ; covered with a 

 few scattered hairs on the dorsal side, and a close growth of much 

 longer ones on the ventral side which is rather flat ; mouth parts 

 ferruginous, jaws tipped with black, coming to a sharp point ; 

 fore part of head smooth, shining and rounded in front ; the 

 segment behind arched over the head, the rest of the thoracic and 

 all the abdominal .segments rounded, smooth, shining, of a uniform 

 size ; anal segment hairy and rather truncate ; larva nearly 

 always curved round and broadest in the centre. 



The larva feeds upon the dead branches of Acacia decurrens, 

 hollowing out the slender twigs, but filling up the irregular tunnels 

 as it feeds along. I obtained a large number of infested twigs 

 from a dead Acacia near Carlingford containing numbers of perfect 

 insects, and larvae in all stages of development, in the middle 

 of March. The pupa is of a pale brown colour with black eyes, 

 a small protuberance on either side of the head, and a sharp spine 

 on either side of the anal segment. 



The perfect beetle is 3-| lines long ; rich reddish-brown, covei-ed 

 with very fine golden bronzy scales which show a faint metallic 

 lustre ; two conical projections on the front of the thorax, and a 

 double row of three more rounded protuberances down the elytra 

 with two other pairs towards the apex, and a generally rugose 

 pitted surface on the thorax and elytra, giving it a very warty 

 appearance.
