spot at the base of the primaries, bred from a larva found in 

 Buckingliamshire ; in another the same markings were repro- 

 duced in a colour almost white ; the larva from which this 

 was bred was found in Devon, and both larvae were fed on 

 sallow. With reference to the first example, Mr. South stated 

 that he had had some hundreds of this species through his 

 hands, but had never met with this particular form before. 

 Mr. South also showed an unusually dark form of Larentia 

 didymata, L,, from Durham, where the species had been 

 exceedingly common. 



Mr. Eouttell exhibited a pale form of Zygcena fil/pendulcs, 

 L., from Leigh, Essex, and Hesperia Imeola, Ochs., taken at 

 Southend in 1882, which he discovered in his series of H. 

 thaumas. 



. Mr. Turner showed Zr./m^o/«, taken on the Society's excursion 

 to Leigh. Mr. Nussey exhibited the same species, including 

 a very pale example from Shoeburyness. Mr. Tugwell ex- 

 pressed an opinion that the species occurred on the salt 

 marshes, and those taken on the hills were specimens that 

 had been blown from the salt marshes. Mr. South said the 

 species was plentiful at Tancarville, some 200 or 300 yards 

 from the river Seine, in a limestone quarry, and there was no 

 character of salt marshes whatever. Mr. Barker said he had 

 this year taken a specimen in Sussex, on the chalk. 



Mr. H. Moore exhibited varieties oi Abraxas grossulariata, 

 L., having the spots coalescing in the costa, and also forming 

 bands. One of these was reared upon the Japanese spindle. 



Mr. Jenner Weir exhibited living larvae of Psyche villosella, 

 Och., and drew attention to the different kinds of material 

 from which the cases had been constructed ; one singular 

 case was formed entirely from pieces of rush, each about one 

 quarter of an inch in length ; and although he had had this 

 specimen about two months, it appeared not to have added to 

 its case. Most of the cases had been commenced with the 

 fragments of grass, and afterwards of heath. 



He also exhibited one larva from which he had removed 

 the entire case, and had supplied it with strips of coloured 

 paper, from which in a few days it had formed a new habita- 

 tion. The coloured paper had also been used by another 

 specimen which had not been deprived of its case. During 

 the last two months most of the specimens had doubled the 

 length of their cases. The case was always made from the 

 feeding or proximal end, and never from the distal end, from 

 which latter the imago appears. In one instance where he 

 had made the experiment of cutting off the distal end, the
