the 'Gardener's Chronicle,' 1856, and that attention liad lieen 

 recently called to it by Mr. Douglas in the Ent. Mon. Mag. for 

 December. Mr. Jenner Weir stated that plants in his green- 

 house had been attacked by the same species. 



Mr. PoLilton exhibited the bright green blood of the pupa 

 of SmeriniJiKs tilUc, which is one of many lepidopterous pupfE 

 possessing a chlorophyll-like pigment in the blood. The blood of 

 the larva contains the same pigment in a much smaller amount, 

 while in the pupa the additional colouring-matter fixed in the 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 that of chlorophyll. 



Mr. G. T. Porritt exhibited forms of Cidarin suffumata from 

 Huddersfield, including one very similar to that taken at Dover 

 by Mr. Sydney Webb (Proc. Ent. Soc. 1886, p.xxv.); and ono 

 still more extreme, having only the basal mark and the central 

 stripe, with a sliglit streak at the tip, brown, the remainder of the 

 vpings being perfectly white. He also exhibited a series of small 

 bilberry-fed Hypsipetes elutata from Huddersfield, showing green, 

 red- brown, and black forms. 



Mr. Stevens exhibited forms of Campto gramma bilineata and 

 Emmelesia albulata 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. McLachlan read the following " Note concerning certain 

 NemopteridcB " : — 



"My friend Dr. Hageu has recently published some critical 

 notes on this family in the ' Proceedings of the Boston Society of 

 Natural History,' vol. xxiii. pp. '250 — j269, prompted by my 

 description of a South American species that appeared in our 

 ' Transactions ' for 1885, pp. 376—377. 



" It occurs to me to make the following remarks on some points 

 that seem of interest, but they are only casual, and must not be 

 looked upon in the light of an analysis.
