appeared Oct. 26th. Of the twenty specimens which emerged, 
10 are referable to var. hutchinsoni, and 10 are normal, the 
latter showing both the variegated and plain undersides. Of 
the var. hutchinsoni, three appear to be intermediate between 
that var. and the type, the undersides of the wings being 
distinctly var. hutchinsont, and the uppersides not dis- 
tinguishable from the type. The vars., including the inter- 
mediates, emerged on October 16th, 19th (3), 20th, 21st (2), 
22nd, 23rd and 26th, 1910. It is believed that there is no 
record of var. hutchinsoni having ever been bred in the 2nd 
brood of c-album. Mr. Newman writes: “I have bred 
thousands of c-albwm of the second brood in various years, 
and never one hutchinsoni, and I have never heard of any 
one else doing so.” He added that by the kindness of Mr. 
Newman he was enabled to show a series of Ist brood var. 
hutchinsoni for comparison. 
Mr. H. Rowxianp-Brown and the Cuatrman both observed 
that on the Continent they had taken hybernated specimens 
of P. c-album of the hutchinsoni form. 
Papers. 
Dr. O. M. Revurer communicated a paper entitled “ Bryo- 
corina nonnulla Aethiopica descripta ab O, M. Reuter et B. 
-Poppius.” 
Commander WALKER, one of the Secretaries, read a paper 
on behalf of Col. Manners, entitled “A factor in the pro- 
duction of mutual resemblance in allied species of buttertlies : 
a presumed Miillerian combination of Huploeas in South India 
and Amauris in South Africa.” 
The methods adopted in his experiments, and the conclusions 
drawn from them by the author, were to some extent the 
subject of criticism both by Mr. G. A. K. Marsmatn and Dr. 
CuapmMAN. Mr. Merririetp added a few observations with 
regard to the comparative immunity of Pierine butterflies from 
the attacks of birds. 
Vote of Condolence. 
A vote of condolence with the family of the late Mr. J. W. 
Turr was moved from the Chair, all the Fellows present 
signifying approval by rising.
