the two central spots of the fore-wings reduced to minute 

 dots. 



Mr. Mansbridge exhibited a series of Hypenodes alhistrigalis, 

 Haw., taken at sugar in Epping Forest during July. 



Mr. Sturt exhibited a living larva of Sphinx convolvtdi, L., 

 one of a number which he had received from Cornwall, 

 the others having all gone to earth ; also drawings of the 

 different forms which had occurred in the brood. He 

 stated that he had hoped to have exhibited a pupa, but 

 that larvae which had been down in earth more than three 

 weeks had not yet pupated. Mr. Barrett noted that one 

 of the drawings was of a green coloured larva with stripes, 

 and said such a form, although it sometimes occurred, was 

 most unusual. It was considered doubtful whether the 

 imagines would emerge naturally, and the general advice 

 was that the pupae should be forced. Mr. Adkin said 

 that S. convolvtdi was a native of a hotter climate, and 

 that its larvae in England would not develop at a sufficiently 

 rapid rate to pupate before the approach of winter. Mr. 

 Carrington referred to the York collectors of years ago who 

 were very successful in rearing A. atropos, and who invariably 

 forced their pupae. He described their method of procedure, 

 and said that they always looked for the emergences to take 

 place six weeks after the commencement of forcing. Mr. 

 Tutt said that S. convohndi was a species which had the 

 migrating instinct, but was not capable of easily adapting 

 itself to the new conditions imposed upon it by an English 

 climate. The temperature of its habitat had a much higher 

 average. Its two appearances were in May and August, 

 from the first of which immigrants came over to England. 

 The brood succeeding these would be later, say September, 

 and thus we get late larvae such as the one exhibited, which 

 would undoubtedly have succumbed in the open, from the 

 uncongenial nature of the climate. Mr. South suggested 

 that perhaps autumnal emergence might ensue from larvae 

 which had pupated near the surface, while those larvae 

 which had gone deeper would not attain the imago state 

 until the following spring or early summer. 



Mr. South exhibited a short series of Acronycta nienymt- 

 thidis, View., which he had bred from larvae found on the 

 moors at Macclesfield. Although the larvae of this species 

 is stated to feed on many low plants, he had only found 

 them on sallow and birch, chiefly on the former, which they 

 also preferred in confinement. 



Mr. Carrington exhibited the following series of various
