FEBRUARY 2yd, 1905. 



The President in the Chair. 



Mr. G. H. Briault, of Acton, was elected a member. 



Messrs. Harrison and Main exhibited (1) a series of 

 Hybevnia progemmaria taken in Epping Forest. They were 

 mostly of the ordinary typical forms, a few only being 

 slightly darker ; (2) a series of the same species from the 

 neighbourhood of Liverpool, in which were a number of the 

 dark or so-called black form, var. fuscata, which is stated to 

 be taken in that district very freely ; (3) another series from 

 Delamere Forest, Cheshire, of which most of the specimens 

 were of the ordinary forms, with only a few of the war. fuscata, 

 which is stated to be not very frequently met with in this 

 latter district. 



Mr. Tonge exhibited a series of the same species from 

 various southern localities, especially from Tilgate Forest 

 and Reigate, those from the latter place particularly being 

 prettily variegated. 



Mr. Priske exhibited a short series from Richmond Park, 

 among them being one specimen with a very dark area from 

 the base of the fore-wing up to the margin of the transverse 

 band. This was the only specimen out of all the southern 

 examples which in any way showed a decided tendency to 

 assume the dark suffusion characteristic of the northern var. 

 fuscata. 



Mr. Robt. Adkin's exhibit consisted of (1) a series of the 

 same species bred from wild Yorkshire parents, both of the 

 " black " form, the progeny consisting of 161 individuals, of 

 which 98 were males and 63 females ; of the males 60 were 

 of the " black " form and 38 of a dark form, but lighter than 

 the parent, more particularly in the colour of the hind wings ; 

 the females also were all of the "black " and dark forms, no 

 light forms being reared of either sex. (2) A single male of 

 a somewhat light shade and four females — two " black," 

 one light, and one intermediate, reared from a pairing be- 

 tween a light male and a "black" female Yorkshire wild 

 parents. The majority of this brood perished, the male 

 exhibited being the only one reared. (3) Two black and two 

 light males, eight " black " and four light females, represent- 

 ing the progeny of similar parents. (4) A dark male captured 

 at Rannoch. (5) A light male from the West of Ireland ;
