SOME LEPIDOPTEKA OF THE BKITISH LINE IN FKANCE. 13 



M. jKirthenie was common in a wood near Vaux-en-Amienois, 

 which is easily the best hunting-ground I have come across in 

 this country. Unfortunately my opportunities there were limited 

 to one dull day. 



Araschnia levana I am doubtful about. There was a small, 

 fast, tawny butterfly fairly common about Amiens in April. I 

 had no net in those days and never saw it settle. The summer 

 form did not come my way in Artois. 



Vanessa urticce was everywhere commoner and often larger 

 than in Britain ; also it was more continuous. The hibernated 

 specimens appeared to carry on well into June, when a new 

 brood appeared on the wing. After that fresh and wasted 

 examples were always to be seen together up to September. 



V. io was common everywhere, and in the Vimy trenches 

 abundant, though small. 



Pyrameis atalanta occurred everywhere, but was distinctly 

 rare in Artois in August and September. Carclui I did not see. 

 Melanargia galatea, abundant near Amiens ; not uncommon 

 at Souchez, where it occurred over a much larger area. 



Pararge egeria, var. egerides was common in the spring at 

 Corbie. I did not meet with the summer brood in Artois. 

 Both broods of P. megcera were very plentiful. 

 Satyrus semele I found only on one rough hillside near Bruay. 

 Epinephele janira was common everywhere. In the south, 

 however, its distribution was distinctly patchy. It was to be 

 found in some meadows or marshes and not in others. Hyper- 

 anthus, on the other hand, swarmed everywhere, and produced 

 some good minor variations. 



E. tithonus was unaccountably rare and was seen in only 

 two places — two specimens near Souchez and good numbers 

 near St. Pol. 



Cocnonymijha 'pamphilus, abundant everywhere and producing 

 some line large specimens. 



Theda hetulce was the only hair-streak I saw, a single 

 specimen being taken by a friend near St. Pol. It was abundant 

 near Bruay. 



Chrysophanus pldosas did not show itself at all till August, 

 when it was not uncommon near Souchez and St. Pol. No 

 aberrations were taken except one or two with a trace of blue- 

 spotting on the hind wings. 



I have been very disappointed in not meeting with any of 

 the other " coppers." 



Of Lyccena astrarche I have taken only two specimens, one 

 near Corbie early in the year and one near Bruay in September, 

 In each case careful search was made for more, but without 

 success. 



L. icarus is of course abundant all along the line, and my 

 series of it is perhaps the best part of my very limited conti-
