SEPTEMBER 22nd, 1887. 



R. ADKIN, Esq., F.E.S., President, in the Chair. 



Mr. Jager exhibited CallimorpJia hera> L., and var. 

 hitescens, Staud., from Starcross, Devon, and stated that he 

 had obtained ova, and now had the larvae feeding. 



He also exhibited Stilbia anomala, Haw., taken near 

 Tenby, on heather. These were all males, and Mr. Jager said 

 he had been unable to meet with the female of the species. 

 The males, however, were fairly common one night, but after- 

 wards very few were seen. 



Mr. Adkin remarked that he understood this frequently 

 occurred with this insect. 



Mr. Sheldon exhibited Xanthia fulvago, L., and var. 

 flavescens, Esp., and said they came from a valley in Derby- 

 shire. It was remarkable that this valley alone of all the 

 surrounding district produced, to a large extent, melanic 

 specimens ; in the neighbourhood the Lepidoptera found were 

 generally of the light southern forms, while in this particular 

 valley many species were almost black ; for example, Teph- 

 rosia biundularia, Bork., Thera variata, Schiff., and others. 



Mr. Cooper exhibited series of Ephippiphora obscurana, 



St., from Epping Forest, Eugonia quercinaria y Hufn., among 



which were many interesting dark forms ; Melanippe galiata, 



Hb., examples of the second brood ; dark forms of M. 



fluctuata> L., from Aberdeen. 



Mr. Goldthwaite asked whether the specimens of E. 

 quercinaria had been bred from an ordinary female, or from 

 one showing any strong dark markings, as he had obtained a 

 batch of eggs from a very dark female, and did not breed a 

 single specimen worth calling a variety. 



Mr. Cooper, in reply, said that the female from which the 

 ova were obtained was so worn that it was impossible to say 

 whether it varied from the ordinary form or not. 



Mr. Goldthwaite exhibited varieties of the underside of 

 Lyccena bellargus, Rott, including an underside of the male of 

 the obsolete form.
