on the disc of the fore-wing ; two in which the yellow mark- 

 ings were extended and greatly predominating over the dimin- 

 ished darker markings ; and a very dark example with many 

 of the black markings enlarged and run together. 



Mr. Robert Adkin exhibited a series of Cossus lignipcrda, 

 taken at Lewisham in June last. He said that it would, 

 perhaps, be remembered that, some nine years ago, he 

 exhibited a similar series, and read a short paper on the pupa- 

 tion of the species (" Proceedings," igoo, p. i). The specimens 

 now exhibited were, with one exception, taken on the same 

 dwarf fence as the earlier examples, just on the inner side of 

 which, and within a couple of feet of it, grew the poplar 

 trees in which the larvae had fed, originally some half dozen 

 in number, but now reduced by the attentions of this species 

 to two and a dead stump some two feet high. The moths were 

 collected between 6 and 7 o'clock in the evening, as they 

 rested on the fence, drying their wings ; and as a rule within 

 a foot of the empty pupae skins they had just vacated. These 

 were generally protruding from the light, friable, earthy 

 rubbish that had collected between the staves of the fence 

 and the skirting board, but in one case from a round hole 

 near the bottom of one of the staves, and in another from the 

 skirting, the larva in each case evidently having bored 

 nearly through the wood before pupation. The one exception 

 referred to above is that of a moth taken at a distance of 

 upwards of ninety yards from any tree where the larva was 

 likely to have fed. I have not the least doubt that it had 

 fed up in the same poplars as the others ; that in starting 

 its wanderings on quitting the tree, it travelled to the end of 

 the fence about the foot of which the others pupated, where 

 its only choice was between the asphalt foot-path and a 

 brick wall ; that it continued its way along the foot of the 

 wall to its end, where it encountered another fence. From 

 the soft earth collected in the corner between this wall and 

 the fence the pupa skin was protruding, the moth sitting 

 with wings still limp afoot or so above it. 



Mr. Hy. J. Turner exhibited living specimens of Lyonetia 

 clerckclla, bred from cocoons found at Oxshott during the 

 Society's Field Meeting on October 8th. The larva makes 

 a tortuous mine in the leaf of birch, which it abandons when 

 ready to pupate. The cocoon is made of pure white silk, 

 suspended among numerous threads stretched between the 

 sides of a wrinkle on the lower surface of the same or some 

 other leaf. An empty cocoon was also shown. One of the 

 imagines was ab. areella, a specimen of a nearly uniform
