Mr. Winkley exhibited two specimens of a second brood 

 of Smerinthus populi, L., bred by himself; the ova were laid 

 in April, and the imagines came out in the middle of August. 

 He had taken no particular care of them, and they were 

 somewhat smaller than those of the usual brood. 



Mr. Winkley also exhibited some of the results of his 

 experiments in breeding Helix poniatia, L., from the ova. In 

 one of his large flower-pots, containing the mature molluscs, 

 he had recently found four clutches of ova ; in the first cavity 

 were 62 eggs just hatching, in the second cavity 36 young 

 just emerged, in the third 63 ova on the point of hatching, 

 and in the fourth i ovum also hatching. He thought the last, 

 consisting of a single Q^g on the point of hatching, to be 

 very remarkable, but suggested that he may have removed 

 the parent while engaged in laying. Finding these clutches 

 so recently seemed to him to suggest that there are two 

 broods. Mr. Step thought that in years like the present, 

 when the continued moist atmosphere was so conducive to 

 molluscan life, the breeding went on without cessation 

 throughout the summer. He remarked that the specimens 

 exhibited were dark and mottled so as to closely resemble 

 the young of Helix aspersa, L., but did not think that this was 

 due to their food (lettuce). 



Mr. Filer exhibited a long series of Papilio niachaon, L., 

 from Cambridge, bred during 1893 and 1894. I" ^^^ ^^^ 

 specimens there was a very considerable development of 

 bluish scaling. One specimen had the black marginal band 

 on the secondaries extended inwards sufficiently to meet the 

 discoidal spot. On the primaries of another specimen the 

 third of the central light blotches from the inner margin 

 contained a distinct black spot. 



Mr. H. Moore exhibited a specimen of Vanessa urticcu, L.. 

 taken in August at Chaunai, Vienne, having the two central 

 spots represented by only a few dark scales ; he also exhibited 

 two cocoons of Saturnia pavonia, L., and stated that many 

 roads south of the Loire were strewn with dead larvae which 

 had been killed while wandering by passing vehicles. 



Mr. Williams exhibited a tube containing a specimen 

 of the intestinal worm Gordiiis aquaticus, which had emerged 

 from the body of a water spider taken at Wisley. Several 

 members had seen lepidopterous larva attacked by similar 



parasites. 



Mr. A, Hall exhibited a number of species of Rhopalocera 

 he had received from Japan, among them being several 

 identical with those found in Great Britain, such as Papilio
