BUTTERFLY HUNTING IN THE NEW FOREST. 55 



carices, or flying slowly when disturbed. The uniform, or nearly 

 uniform, colour of the under side of the hind winj]j (noted by Tutt) 

 is perhaps the most obvious character distinguishing this species 

 h'omjiava, in which the ])Osterior one-third of the wing is of a 

 much brighter yellow than the rest. We saw two or three early 

 examples of the second emergence of P. macJiaon. 



I made several visits to Eoyston in August, where, in company 

 with Dr. Keynes. I was chiefly concerned with the semuyngrapha 

 form of ? corxjdon, of which we took many fine specimens, 

 tliough all fell far short of the full sijngrapha form found in the 

 Chilterns by Mr. Eowland-Brown. Two visits to the Devil's 

 Ditch, near Burwell, conlirmed, so far as they went, the result 

 of Mr. Geofi'rey Keynes,'^ that the semisyngrapha form is not 

 developed there to nearly the same degree as at Eoyston. 



I took a beautij'ul "striated" example of Aricia meclon on the 

 Devil's Ditch, near Burwell, in which all the spots internal to the 

 rows of orange lunules on the under sides of both fore and hind 

 wings are elongated towards the bases of the wings, and the spots 

 external to the orange lunules are absent. It does not appear 

 to correspond with any variety described by Tutt.t 



I captured a minute example of P. icariis on Teversham Fen, 

 a male measuring only 19 mm. across the wings— less than my 

 smallest example of minimus. 



My visits to Eoyston added Angiades comma, the Silver- 

 spotted Skipper (another new species for me in England), which 

 was rather abundant on the further part of the Heath, about 

 low-growing thistles {Carlina acaidis) and Campanula glomerata. 

 Males were out on July 27th ; by August 6th the females had 

 become frequent. 



Our visit to Dorset was a good deal impaired by wet and 

 windy weather, but butterflies were about in abundance when 

 the sun came out. We spent the first fortnight at Beaminster 

 and moved on to Dorchester for the first week of September. 

 The Vanes&ids were perhaps the most striking feature. Cardui 

 was very scarce. lo and atalanta were in great abundance on 

 brambles in sheltered [)laces on the higher ground and urticce 

 was common. We took a very finely marked aberration of the 

 latter which appears to be near the form atrebatensis of Bois- 

 duval,+ as accepted by Eaynor.§ The specimen is almost inter- 

 mediate between those figured by South. || The fore wing 

 resembles that shown in Fig. 22, and the hind wing and under 

 side are as in Fig. 23, Except that the row of blue lunules in mine 

 appears to be better marked. It is almost exactly like that
