of another new Species of Paussus. 27 



small, the maxillae are very thin and semitransparent, terminating 

 in two deflexed hooks. The prothorax is quasi-bipartite, the 

 anterior part very slightly broader than the head, with the lateral 

 angles acute ; it is dilated behind in the middle, and has a longi- 

 tudinal depression in the centre, not reaching to the anterior 

 margin; the hind part has the lateral portions elevated and of a 

 blackish colour, with a small patch of fulvous hairs in front : the 

 centre of the prothorax is deeply impressed, the hind central 

 portion forming two lobes rounded in front. The elytra have a 

 large black patch, occupying at least half of the hinder portion of 

 the disc, leaving a narrow rufescent margin ; they are margined 

 with numerous long reddish bristles, both along the sides and 

 posterior margin ; the podex is also similarly margined with shorter 

 hairs. The femora are pitchy, and the remainder of the legs 

 reddish ; they are comparatively short and stout, without any 

 marked distinction between them in size or thickness. The basal 

 joint in all the tarsi is minute. The entire insect is destitute of 

 gloss on the surface ; it is very obsoletely punctured, but it is 

 clothed throughout with very minute luteous setse.

VII. On the Gall formed hy Diphucrania auriflua, Hope, a 

 Species of Buprestidse. By W. W. Saunders, Esq., 

 F.L.S. 



[Read 7th February, 1847.] 

 (PI. II. figs. 5—9.) 



Mr. Wm. Stephenson, while resident at Sidney, New South Wales, 

 discovered a kind of excrescence or gall on the branches of 

 Pultenaea stipularis, and having obtained several for examination, 

 it became evident to him that they were caused by the larva of a 

 small Bupresiis, which I find to be the Diphucrania auriflua of 

 Mr. Hope (PI. II. fig. 9). Mr. Stephenson, supposing this fact 

 to be new to Entoimologists, kindly forwarded to me a series 

 of the galls, containing both the perfect insect and the larva, from 

 which I have been enabled to draw up the following account, 

 which I beg leave to lay before the Entomological Society. To 

 allow me to see the insect in its various states Mr. Stephenson 

 immersed the galls soon after obtaining them in boiling water, by 

 which means the vitality of the insect was destroyed, and by 

 cutting the galls open I was able to take out both larva and imago,
