adverse circumstances common species were quite as fully- 

 represented as usual, perhaps even more abundantly so ; 

 indeed, the crowd of butterflies that rose from one's feet 

 when walking through the long grass on the sea front was 

 a sight to be remembered — a motley multitude, possibly 

 driven together by stress of weather Vv^here some little shelter 

 might be found. 



The following is a list of my captures : — 



Among the butterflies, the Pieridae were represented by 

 Puris brassiccB, L., P. rapes, L., and P. napi, L., all equally 

 common, thus contrasting strongly with their appearance in 

 1887, when, although the two first-named species were 

 unusually abundant, the last was so scarce that I failsd to 

 detect a single specimen, although I was over the same 

 ground frequently, and at the same' time of the year. 



Argynnis aglaia, L., pursued his wild career over the 

 broken ground of the undercliff. The majority of the speci- 

 mens secured were in a dilapidated condition ; but in one, 

 apparently freshly emerged, the fore-wings were unequally 

 developed, that on the left side being less than half the size 

 of that on the right, and in the smaller wing the rows of 

 round spots and submarginal crescents are united, forming 

 broad streaks both on the upper and under side. 



Satyrus semele, L., and EpinepJiele ianira, L., wei"e very 

 common. Some few Pararge niegcEra, L., were flying about 

 the precipitous fronts of the cliffs, and the second broods of 

 Ccenonympha paviphilus, L., and Polyommatus phlcsas, L., 

 were just beginning to appear. 



Lyccsna corydon, Fb., was well out when I arrived on the 

 scene at the beginning of August, and continued very 

 common during my stay, as did L. teams, Rott. L. bellargus, 

 Rott., was first noted on 22nd, and continued to appear in 

 increasing numbers up to the time I left. I spent a good 

 deal of time in examining these species whenever practicable, 

 but although so common on the wing in the morning sun- 

 shine and at rest on the grass stems, knapweed flowers, etc., 

 on the calmer evenings, they were missing when it was dull 

 and stormy. That such a multitude should suddenly dis- 

 appear was evidently impossible, and I resolved to find out, 

 if possible, what became of them. After a lengthened search 

 among the dense clumps of grass, where I found some few 

 resting in sheltered positions, and searching lower and lower 

 in among the clumps I began to find them more commonly 

 until I hit upon the majority almost down among the roots. 

 No unusual variation was noted. L. corydon produced some
