Mr. Robert Adkin exhibited Lepidoptera from the Scilly 

 Isles, and contributed the following note : — " In June of 

 last year my brother, being on a visit to the Scilly Isles, 

 very kindly captured and sent to me, in a damp box, such 

 species of Lepidoptera as he was able to obtain in the time 

 at his disposal. Unfortunately, owing to some delay in the 

 box reaching me, many of the insects had been attacked by 

 mould ; but I was able to rescue some few before they were 

 entirely spoiled. These were, — Pieris rapes, L., and P. napi, L., 

 both of a very ordinary form and showing no tendency to 

 variation. LyccEna icarus, Rott., several males normal ; the 

 only female, much shot with blue, and the ocelli at the apex 

 of primaries whitish ; one male has the two inner spots on 

 the costa of secondaries on the underside united. Cidaria 

 truncata, Hufn., several somewhat large, and more or less 

 suffused with dull greyish brown. Camptogramma bilineata, 

 L., several very ordinary specimens. Indeed, the most re- 

 markable circumstance appears to be that, although at least 

 three of the species, i.e., P. napi, L. icarus, and C. truncata, 

 are known to be liable to somewhat pronounced local varia- 

 tion, the specimens from these remote islands should be 

 normal. From some flower-heads of Silene maritima, which 

 my brother found growing in some abundance in one or two 

 restricted localities, I bred five specim.ens of Sciaphila con- 

 spersana, Dougl., some of which are decidedly more strongly 

 marked than any that I have seen from our south coasts, 

 and one female of Sphaleroptera ictericana, Haw."
