NOVEMBER iT,ih, 1890. 

 W. H. TUGWELL, Esq., Ph.C, Vice-President, in the Chair. 



Messrs. G. Champion, A. J. Hodges, and A. J. Hill were 

 elected members. 



Mr. Wellman exhibited specimens of BryopJiila impar, 

 Warren, from Cainbridge, and a specimen of B. miiralis, 

 Forst., from Folkestone, closely resembling the specimens of 

 inipar. Mr. Tugwell said that in his opinion ivipar was 

 nothing more than a local variety of muralis, and certainly 

 the Folkestone variety was characteristic of the so-called 

 inipar. 



Mr. Tugwell exhibited long series of Cerastis vaccinii, L., 

 and C. spadicea, Hb., to show what appeared to him to be the 

 gradual merging of the two forms or species ; it would be 

 noticed in the series that the two ran so close that it was 

 practically impossible to separate them, that although we had 

 no difficulty in distinguishing well-marked examples, others 

 ran into intermediate forms difficult to separate. Mr. South 

 said that spadicea was a form of vaccinii, and was figured by 

 Hubner ; but the form known here as spadicea was known on 

 the Continent as snbspadicea, which was said to be a form of 

 C. ligida, Scop. Mr. C. G. Barrett remarked that he had no 

 difficulty in separating one from the other, the chief distinc- 

 tions being in the shape of the forewings ; '(ho'~,^.oi vaccinii 

 being broad, obtuse, and dilated at the anal angle, those of 

 spaaicea=iligula narrower, and sharply angled at the apex. 



Mr. R. Adkin exhibited Peronea spojisana, Fb., from the 

 New Forest, and referred to his exhibit of this species ni 

 1889, when nearly all shown were the variety tristana. Haw. 

 At the time some observations were made that usually this 

 variety only occurred sparingly among the ordinary form ; 

 this year he had endeavoured to get the insect as it occurred 

 in the Forest without having them picked ; and out of some 

 twenty specimens, all that were taken, only four or five were 

 the variety, and they gradually approached the type ; none ( f 

 the specimens were exactly like tliose taken the previous 

 year. 



Mr. R. Adkin also exhibited examples oi Spilosoma inendica, 

 Clerck., bred from ova obtained by the pairing of a female of 

 the Irish form (van rustica, Hb.) with a male of the English 

 variety of the species ; from the ova obtained only two moths 

 were bred, both of which were males, and neither of them 

 were like either the English or Irish form. 



Mr. Henderson exhibited eggs of the Great black-backed
