latter, the species being hitherto unknown as an inhabitant 

 of these Islands.

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



Mr. Dennis exhibited strongly-banded examples of Spilo- 

 soma lubricipeda, Esp., taken in his garden at Hackney, and 

 remarked that he obtained this form every year. 



Mr. Hawes exhibited pupae of Pararge megcera, L., and 

 remarked that out of a brood of about five dozen larvae, 

 reared from eggs obtained about June 12th, he had obtained 

 a form of the pupa which would seem to have hitherto 

 escaped notice, viz., a sooty black variety relieved only by a 

 double dorsal chain of chrome yellow spots. About one- 

 fourth of the brood were of this form, and four or five others 

 had the usual emerald colour replaced by a darker and duller 

 shade of green. Although so different in the pupa state the 

 resulting insects from the whole brood of larvae showed no 

 variation as between black and green pupae, but the imagines 

 from the black differed inter se, as did also those from the 

 green pupae. It was interesting to add that the empty cases 

 of the black pupae retained their dusky appearance, while 

 those of the green pupae were, as usual, almost transparent. 



Mr. Turner exhibited Bupalus piniaria, L., bred from larv^ 

 taken at Westerham, showing pale and dark forms of the 

 female. Mr. Barrett remarked that the white northern form 

 of this species might be considered the type, as it occurred 

 over a much larger area than the darker southern form, and 

 was also more frequent on the Continent. 



Mr. Waller exhibited, among others, bred specimens of 

 Aplecta tincta, Brahm., Eupithecia venosata, Fb., and Dian- 

 thcBcia carpophaga, Bork., from the southern counties. Mr. 

 Barrett, referring to the last-named species, made some 

 remarks on their interesting stages of variation, and called 

 attention to one of the specimens having an abnormal addi- 

 tional wing. 



Mr. Billups exhibited several species of British Diptera, 

 amongst which were some of comparative rarity. Saproniyza 

 decempunctata, Fin., two specimens taken in his own garden 

 at Dulwich on the 8th of June, 1890, and a solitary specimen 

 from Oxshot, taken the nth July, 1891. Also two specimens 

 of Chlorops hypostigma, Meig., taken in June and July 

 respectively last season in his garden ; this latter species not 

 being recorded in Mr. Verrall's List of British Diptera, 

 publi:5hed in 1888. Fackygasier leackii, Curt., two specimens
