ties occurred, Mr. Fruing Warne securing a black specimen 

 of this species ; and he was also fortunate enough to obtain a 

 variety of Tephrosia crepuscularia, Hb., the ground colour 

 being yellow. It was stated that none of these species were 

 plentiful, and it was attributed to the lateness of the season 

 and the extremely cold winds which were prevalent at the 

 time. Mr. E. Step obtained a good many species of mosses. 



JUNE lUk, 1 89 1. 



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



Mr. C. S. Bouttell exhibited a series of Core^nia ferrugata, 

 Clerck., and of C. tmidentaria^ Haw., and remarked that the 

 latter species bred from the black-banded form in every case 

 remained constant, while those from the red-banded form 

 varied considerably. 



Mr. Tutt exhibited two specimens of Vanessa atalanta, L., 

 and remarked that five specimens were bred from larvae col- 

 lected by him at Deal ; the specimens were remarkable in 

 having the right superior wing very small, but perfectly de- 

 veloped ; this, Mr. Tutt said, he attributed to a diseased 

 condition of the larvae. 



Mr. Tugwell exhibited Spilosoma mendica, Esp., bred from 

 ova received from Mr. Porritt ; and specimens sent from Mr. 

 Harrison as the normal form in the Barnsley district. Mr. 

 Tugwell pointed out that the males of the species from 

 Barnsley were paler and smaller than the usual southern 

 form, and gradually toned down toward the var. rustica ; 

 whilst in those bred from the Huddersfield parent the males 

 were blacker, and the females more spotted than the southern 

 type of the species. 



Mr. R. Ad kin exhibited examples of club moss {Lycopodium 

 selagd) from Rannoch, and remarked that it was a mountainous 

 species, and not found in the southern parts of England. Mr. 

 Tugwell said it was common in the high wet mountains, both 

 at Rannoch and at Braemar. Mr. C. G. Barrett remarked 

 that he had once found this club moss at Haslemere on a 

 heathy hill-side. 



Mr. Ruffle exhibited an example of the masked crab 

 {Corystes cassivelaunus). Mr. West (Streatham) said he had 

 seen this crab off Hastings, and had found some dozens of 

 them. Mr. Tugwell referred to his having taken on more 

 than one occasion a quantity of oysters at Littlehampton, 

 which were washed in shore from the beds, owing to rough 

 weather.
