pilosaria, Fb., six dark examples taken in the above-men- 

 tioned park, Feb., 1894. This form is not at all common. 

 Abraxas Jilinata, Fb., the most plentiful insect during 1894. 

 The specimens exhibited were selected from a very large 

 number examined. Hybernia progetmnaria, Hb., dark and 

 intermediate forms. Phibalapteiyx lapidata, Hb., a series 

 from Fintry, near Glasgow. Boarmia repandata, L., a series 

 of dark specimens bred from larvae taken in 1894. This 

 species is not common, but is mostly black, in the Rotherham 

 district. 



Mr. Robert Adkin exhibited a considerable number of speci- 

 mens of Melanippe fluctiiata, from various parts of England, 

 Scotland, and Ireland, and remarked that although among 

 those from each district there were individuals varying from 

 the type, both as to considerably increased size and varied 

 ornamentation, the majority of the specimens resembled one 

 another very closely, and he thought it would be wrong to 

 suppose that the species had assumed any special form, other 

 than the type, in any particular locality. 



Mr. W. A. Pearce exhibited the following Rhopalocera 

 from the United States of America, to illustrate Mr. Mans- 

 bridge's paper: — Pieris rap(£, L., Chrysophanushypophlceas, Bd., 

 Lyccena pseudargiohis, Bd., Vanessa antiopa, L., V. atalaiita, 

 L., and Grapta comma, Harris., from Pennsylvania; and Colzas 

 eiirytJieme, Bd., and Vanessa cardui, L., from Colorado. 



Mr. Mansbridge then read a paper entitled, " The Lepi- 

 doptera of the Indian Territory" (p. 120), and exhibited a 

 large number of specimens in illustration thereof. 



A discussion ensued. Mr. R. Adkin stated that he was 

 especially interested in migration, and thought that Mr. 

 Mansbridge's observations on this subject were particularly 

 useful. Mr. Tutt referred to Colzas eurytheme, Bd., noting 

 that the spring brood of that species was pale yellow, the 

 summer brood a dark yellow with a pale costa, while the 

 autumn brood had pale yellow males and dark yellow females, 

 and compared it with the European species C. edzzsa, Fb. 

 He had no doubt that the two species were of common 

 origin, arising when a temperate climate existed in more 

 northern regions. He thought, however, it was a mistake to 

 call C eurytheme a variety of C. edzisa. He would prefer to 

 call each a " species," using this term in the ordinary conven- 

 tional way. Of the migration oi Anosia arcJiippus, L., he had 

 read all the collected evidence, and considered it most unsatis- 

 factory. The general opinion was that it went south in 

 autumn and returned north in spring, only wintering in the
