remarkable examples of Anthrocera fiUpenduhc ab. c/misantheini, 

 bred at St. Anne's-on-Sea, in 1914, in which the red coloration is 

 mostly obscured by dark brown or black suffusion. 



Mr. A. H. Jones exhibited a male aberration of Melanaiy/ia (/ala- 

 thea taken at Folkestone, showing decrease of black marking on the 

 upperside, so that the central transverse white area was regular and 

 continuous ; a female example of the same species from the 

 Splugen Pass in which the markings on the underside of the hind- 

 wings had coalesced to form a complete band ; an A()riades coridon 

 taken at Deal by Mr. Charles Fenn, a female of the very pale brown 

 form known as ab. i<allida ; an ab. pallida of Ccenony)iiplia pam- 

 philus from Ofcford ; and three examples from Eltham showing the 

 recent spread of melanism, Amphidasis betidaria var. dnuhledaijaria, 

 Thera van'ata, a modified var. obliterata, and Cidaria iiinnanata, a 

 dusky form. 



Mr. W. Schmassmann exhibited very fine examples of the follow- 

 ing species of Oniithoptera : — 



Ornithoptera li/diua, three male forms ; O. cnesus, male; O. home- 

 vianni, three male forms ; 0. poseidon ab. valentina, male ; O. 

 poaeidon, female form kirschi ; 0. poseidon, female form brnnnens ; 

 0. pnradisea, male; and 0. paradisea, a variety not showing the 

 golden streak situated towards the tail of hindwing and having in 

 consequence the green marginal area of hindwing much increased.

 M. jiistititc, 31. amphitrion, M. cacica, Al. rhetenor, and M. aureola. 



Mr. W. West (Hon. Curator) exhibited fourteen drawers of Lepi- 

 doptera from the type reference collection of the Society, which 

 have been completely rearranged smce the large additions contributed 

 by Mr. W. G. Dawson, of Abbots Morton, Worcester. 



Mr. C. P. Pickett exhibited four cabinet drawers of his interesting 

 collection of the forms of Aivjerona pninaria, the results of seven- 

 teen years of inbreeding and of four years of experiments in ex- 

 posing the larvffi to various colour environments. The results 

 obtained under the latter conditions are somewhat remarkable as 

 the following summary shows : 



Larvfe ted up under pink muslin : — There was a tendency to 

 reduce the size of the bands and many specimens were paler. 



Larvae fed up under red muslin : — There was a tendency to 

 greatly increase the size of the bands and many specimens were 

 darker. 



Larvae fed up under yellow muslin :— There was a tendency to 

 produce a deeper yellow ground.
