496 ENTOMOLOGICAL NOTES, 



Pemp. Till ides. Obscure ferruginea ; elytra lunula mediaiid 

 macuUsque versus apicem 3 aureis ; antenncB fuscce, argenteo- 

 anmdat<s. (Corp. long. '425 unc. ; lat. '09 unc.) 



This insect has very strikingly the habit of a Tillus : the head is 

 prone and partially received into the prothorax, which is rather 

 elongate and cylindrical, and has a tubercle on each side, rather 

 nearer the elytra than the head : the elytra are linear, some- 

 what wider than the prothorax, and somewhat rounded when 

 taken together : all the legs are of moderate length and pro- 

 portions, and the femora are slightly incrassated externally : the 

 third and fourth joints of the antennas, taken separately, are each 

 manifestly shorter than the fifth, a character which I have not be- 

 fore observed in any longicorn insect. The colour is an obscure 

 ferruginous, with little variation : on each of the elytra is a small 

 golden lunule near its centre, and three or four spots near the 

 apex, of the same colour: the antennae have a slight silvery ring 

 on the fifth, sixth, seventh, and eighth joints. 



Inhabits New Holland. A single specimen was taken by 

 Mr. Imeson, at Woodside, near Sydney. 



Genus. — Rhopalophora ? Serville. 



Rhop. resplendens. Caput cyaneum ; fades tiridi-csnea ; an- 

 tenncB chalybece extus nigricantes ; prothorax antice lesvis, 

 cyaneus, postice rugose punctatus, viridi-ceneus ; scutellum 

 mridi-csneum ; elytra velutina nigro-viridiai basi suturdque 

 viridi-ceneis ; pedes cyanei, tarsis nigris. (Corp. long. '7 

 unc. ; lat. '125 unc.) 



The head is metallic glossy blue, with the face golden green ; the 

 anterior part of the head is elongated : the antennae are metallic 

 blue, nearly black towards the extremities : the prothorax is about 

 as wide as the head, and restricted before its anterior and before 

 its posterior margin ; the anterior portion is smooth, glabrous, and 

 beautifully blue, the posterior portion is rugosely punctured, gla- 

 brous, and golden green : the scutellum is golden green : the 

 elytra are velvety, and of a dark olive green, approaching to 

 black, with the extreme base and the suture glabrous and golden 

 green : the legs are metallic blue, the incrassated portion of the 

 tibiae being very brilliant : the tarsi are black.
