AUGUST Wi, 1889. 

 T. R. BiLLUPS, Esq., F.E.S., President, in the Chair. 



Mr. T. R. Billups exhibited a female specimen of Bracon 

 roberti, Wesm., taken in his garden at Peckham ; a series of 

 Ascogaster instabilis, Wesm., A. varipes, Wesm. (both sexes 

 being represented) from Derry ; also galls on Salix herbacea, 

 L., and their maker Nematus herbacece, Cam., from Aberdeen. 



Mr. Dawson exhibited a specimen of Polyommatiis phlczas, 

 L., var. scJwiidtii, Gerhard, taken at Plumstead ; an example 

 of Deilephila livornica, Esp., from Plymouth, 1888 ; and a 

 variety of Tceniocanipa incerta, Hufn., taken at Plumstead. 



Mr. Carrington, referring to the variety schmidtn, said he 

 only knew of two or three having been taken during the last 

 ten or fifteen years. Mr. Tugwell said, however, that he could 

 not agree with this statement ; he thought that in nearly all 

 the principal collections there were, if not the variety itself, 

 forms of phlcBas closely approaching it. 



Mr. E. Joy exhibited a variety of Epinepliele hyperanthes, 

 L., with the whole of the spots on the under surface much 

 enlarged. 



Mr. Dennis exhibited specimens of BryopJiila perla, Fb., 

 including several yellow examples, and one having the superior 

 wings almost entirely suffused with black. 



Mr. R. Adkin exhibited a specimen of Chcerocampa porcellits, 

 L., together with its cocoon, and said that the larva from 

 which it was bred was taken at Eastbourne in the previous 

 autumn, and being of small size was placed in a leno bag with 

 a quantity of Galium to feed up ; when next observed it was 

 found to have formed a pupal chamber in one of the folds of 

 the leno by lining it with a substance resembling a film of 

 gelatine, slightly flexible to the touch and apparently of a 

 damp resisting nature, and he was of opinion that it repre- 

 sented the lining of the earthen cell made by the larva when 

 allowed to pupate under natural conditions, but which was of 

 so delicate a structure as to prevent its being detected when 

 a pupa was removed from the earth. He further said that 

 this pupa had been allowed to remain in its cocoon without 

 other protection from the air until the imago emerged, after
