BUTTERFLIES COLLKCl'ED IN THE PYRENEES. 195 



sudden rainstorms must be reckoned as one of the disadvantages 

 attendant upon collecting in the Pyrenees. A disadvantage 

 attendant upon the collecting of mountain species in general is 

 that, when a man past middle life has climbed 1500 or 2000 ft., 

 the necessity of sitting down to rest (if weather permit?) is forced 

 upon him, and he is not in a fit condition to run down mountain 

 butterflies, for some species are so shy that they can be approached 

 in no other manner. 



As our Government has re arranged the hours of the day and 

 night, let us, imitating it, re-arrange the years, and begin with 

 May and June, 1918, following these with June, July, and August, 

 1917. We thus obtain a rudimentary lepidopterist's calendar as 

 follows : The season began most auspiciously. I caught in May 

 Thais riimina, var. viedes'icasre (the only one seen alive), E. 

 autiopa (taken also at Perpignan in March), a Hesperiid, and 

 Melitcea ])hoehe. The Hesperiid closely resembles P. sao, if it is 

 not a form of that species. The under surface of the hind wings 

 is dull reddish-brown with pearly white spots, and the nervures, 

 being of a much lighter brown than the ground colour, appear 

 very distinctly. Another example, taken in the same locality ki 

 August, is more brightly coloured underneath. I think that the 

 ♦-xample which I took at Vernet-les-Bains, being smaller and 

 much paler, is probably merely a form of sao. 



In June, 1918, the principal capture made at Amelie-les- 

 Bains has been a podalirius which I have good reason to believe 

 to be vsLY. feisthamelii (June 9th). It is rather above the average 

 size of podalirius, the ground colour is white, the costa and 

 hind margin of the hind wings are yellow which contrasts 

 with the ground colour, the streak above the anal spot is 

 dark chocolate-brown, a line between two black lines on the 

 under surface of the hind wings is paler chocolate-brown, the 

 abdomen is. yellowish-white with four interrupted black lines, 

 two underneath, and two at the sides, a broad black stripe above 

 which tapers to a point at the anal extremity. Another example 

 which was caught on May 18th in the same locality differs from 

 that' described by its smaller size, and also in having only 

 two abdominal black lines which are uninterrupted, and much 

 thicker than on the other example. The ground colour is not 

 so white. The long tails of the tiist-mentioned example have 

 a very evident twist which reminds one of the twist in the 

 leaf-stalks of the blue-gum. The other captures made at 

 Amelie-les-Bains in June were Plebeius cecjon 3 , Agriades 

 bellargus, ab. ceronus, Cupido minimus 2 , Melitcea cinxia <? , 

 Brenthis selene <? 5 , Epinephele jurtina J , and E. jartina, 

 var. hispxdla $ . And at La Preste Parnassiiis delius S , 

 Agriades hylas 3 (the hylas captured at Menton was $ ), 

 Polyommatus meleager 3 , A. urticoi $ ? , Melitcea cinxia ? , 

 B. euphrosyiie, Erebia neoridas, Ilesperia serratidce, and H.
