macropus from Claremont ; A. pallens from Deal ; Liosomus 

 Troglodytes from Faversliam ; and L. oblongulus from 

 Calerham. 



Brachycentrus siibniibilus Bred. — Mr. W. C. Boyd exhi- 

 bited living larvae of Brachycentrus subnubilus, which had 

 been reared from the eggs. They fed upon Conferva;, and 

 the cases constructed by them were clearly quadrangular 

 (though the angles were not prominent) and very diaphanous, 

 so that the movements of the larvae could be discerned 

 within. 



Petnpelia Davisella Bred. — Mr. Vaughan exhibited Pem- 

 pelia Davisella reared from larvae, feeding in a web, upon 

 slioots of Ulex. 



Biorhiza aptera on Roots of Deodars. — Mr. Mliller re- 

 marked that at a meeting of the Scientific Committee of the 

 Royal Horticultural Society, on the 12th instant. Dr. Masters 

 had exhibited some galls found at Wimbledon on the roots 

 of Deodars. That gentleman had since submitted to him 

 further specimens of this gall, which he had found to agree, 

 in external and internal structure, with those of Biorhiza 

 aptera. Fab., usually occurring on roots of oak. Mr. Miiller 

 stated that he had since bred several specimens of Biorhiza 

 aptera from these Deodar galls, and that he believed it to 

 be the first instance where a true Cynips had been known to 

 transfer its attacks from oak to any species of Conifer. 



Hybrid specimen of Clostcra. — Mr. Bond exhibited a 

 hybrid specimen between Clostera curtula and C. reclusa, 

 partaking of the characters of both parents. 



Congregation of Psen. — Mr. Jenner Weir exhibited speci- 

 mens of a minute species of Psen, which he had observed in 

 large numbers in June last, on a pear-leaf at Lewes. They 

 had congregated together on the surface of the leaf like a 

 swarm of bees, though it was not apparent what motive 

 brought them together. 



Humble-bees wanted for New Zealand. — Mr. Dunning 

 read some portions of a letter which he had received from 

 Mr. Nottidge, enclosing the Eighth Report of the Canterbury 

 (Xew Zealand) Acclinialization Society, and staling that the 

 red clover had been introduced into the colony, but that they 

 had no humble-bees to fertilize the plant. Also that certain 

 Lepidopterous insects had been accidentally imported into
