the capture in the Gerakphur Woods, India, of a large black 

 moth — either a Geometer or a slender-bodied Bombyx — 

 which produced a curious crackling noise when flying ; the 

 species did not come to light, and was quite invisible when 

 flying. There was also a note as to the abundance of 

 Emerald Moths in the same woods. 



Mr. T. D. A. Cockerell read a paper on "Variation,"

APRIL 2%tk, 1887. 



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

 Mr. P. Russ was elected a member. 



Mr. Helps exhibited a specimen of Deilephila livomica, 

 Esp., from Coles Cross, near Crewkerne. 



Mr. Lea exhibited Pachnobia leucographa, Hb., and other 

 species taken in Herefordshire at Sallow. 



Mr. South exhibited a male Lyccena corydon, Fb., and called

 Mr. Jenner Weir remarked that Mr. Edwards' exhibition of 

 Papilio merope, Cram., and the two species or sub-species, 

 P. cenea, Stoll, and P. meriones, Felder, was of great interest. 

 The males of the three from Western Africa, South Africa, 

 and Madagascar respectively, were exceedingly alike, yellow 

 and black swallow-tailed butterflies ; but whilst the female of 

 P. meriones differed but little in colour, and not at all in shape 

 from the male, each of the others had females without tails, 

 and of quite a different shape from the males. As to colour, 

 some of those exhibited of the true P. merope were black and 

 white, closely resembling Amauris niavius, L. ; another
