PROCEEDINGS OF SCIENTIFIC SOCIETIES. 275 



The Secretary exhibited a series of the diurnal and nocturnal Lepi- 

 dopterous insects bred in the Insect House iu the Gardens during the 

 present season. — P. L. Sclater, Secretary. 



Entomological Society of London. 



May 3, 1882.— H. T. Stainton, Esq., F.R.S., &c, President, in the 

 chair. 



The President made some appropriate remarks upon the great loss 

 Science had sustained by the death of Mr. Charles Darwin; and especially 

 referred to his early interest in Entomology by becoming an Original 

 Member of this Society, founded in May 1833, while he was travelling in 

 South America. 



Dr. Evald Bergroth (11, Robertsgatan, Helsingfors, Finland) and 

 Mr. W.J. Williams (Zoological Society, Hanover Square, W.) were balloted 

 for and elected Members of the Society. 



The Secretary read a communication from the Secretary of the Essex 

 Field Club, requesting that Members would join in a memorial to the 

 Conservators of Epping Forest and others, requiring that the Forest should 

 be preserved in its natural condition, in accordance with the Act of 

 Parliament. 



Messrs. M'Lachlan, Meldola, Cole, Fitch, and others expressed the 

 wish of all naturalists that Epping Forest should be retained in its present 

 wild state rather than be converted into a park. 



Mr. W. C. Boyd exhibited a dark variety of Fidonia piniaria, L., taken 

 at Woking in 1880 by Mr. Mugford ; it was a female, resembling, but even 

 darker than, a Scotch specimen. Also a curious pale variety of Anchocelis 

 pistacina, Fabr., captured at Cheshunt last autumn. 



Mr. T. R. Billups exhibited a series of Cryptus migrator, Fabr. These 

 were bred from a cocoon of Trichiosoma betuleti, Klug; four specimens 

 emerged on April 6th, and no others until the cocoon was cut open on 

 April 20th, when thirteen more flew out ; of the seventeen specimens bred 

 only two were females. 



Mr. W. F. Kirby read some notes on a Hybrid between Anlheraa Pernyi, 

 Guer., the well-known oak-feeding silkworm of North China, and A. Roylei, 

 Moore, a North Indian species, also an oak-feeder. The cocoon was fully 

 as large as that of A. Roylei, but instead of there being a considerable space 

 between the outer and inner cocoon there was scarcely any interval between 

 them. A. Pernyi has a similar but much smaller cocoon ; and hence it 

 would appear that that of the hybrid would be of greater commercial value 

 than either." The specimen with its cocoon, also cocoons and imagos of the 

 two parent species, were exhibited.
