larval hypodermis cells also passes into solution in the blood. 

 By means of a Zeiss micro-spectroscope, Mr. Poulton was able 

 to show the most characteristic absorption-band of the pigment, 

 together with its resemblance to chlorophyll. Mr. G. T. Porritt 

 exhibited forms of Cidaria suffumata from Huddersfield, includ- 

 ing one very similar to that taken at Dover by Mr. Sydney Webb 

 (Proc. Ent. Soc. 1886, p. xxv) ; and one still more extreme, 

 having only the basal mark and the central stripe, with a slight 

 streak at the tip, brown, the remainder of the wings being 

 perfectly white. He also exhibited a series of small bilberry-fed 

 Hypsipetes sordidata (elutata) from Huddersfield, showing green, 

 red-brown, and black forms. Mr. S. Stevens exhibited forms of 

 Camptogramma bilineata and Emmelesia alhulata from the Shetland 

 Isles, and a curious variety of Chelonia caja from Norwich. The 

 Secretary read a letter from the Administrator- General of British 

 Guiana, on the subject of the urticating properties possessed by 

 the larvae and pupae of certain species of Lepidoptera collected in 

 Demerara. Mr. M'Lachlan read "A note concerning certain 

 Nemopteridse." Miss E. A. Ormerod communicated a paper 

 " On the occurrence of the Hessian Fly [Cecidomyia destructor) 

 in Great Britain." It appeared from this paper that there 

 could be no longer any doubt as to the occurrence of the insect 

 in this country, specimens obtained in Hertfordshire having been 

 submitted to, and identified by Prof. Westwood, and by Mr. W. 

 Saunders, of London, Ontario. Prof. Westwood said the speci- 

 mens agreed exactly with Austrian specimens in his possession, 

 sent to him some years ago by Mons Lefebvre, who had received 

 them from the late Dr. Hammerschmidt, of Vienna. A discus- 

 sion followed the reading of this paper, in which the President, 

 Mr. C. O. Waterhouse, Mr. Theodore Wood, and others, took 

 part. At the close of the Ordinary Meeting a Special Meeting 

 was held, for the purpose of considering certain proposed altera- 

 tions in the Bye-Laws. The proposed alterations having been 

 explained to the Meeting, were, after some discussion, agreed to, 

 and the proceedings terminated. — H. Goss, Secretary.
