THE IiEPIDOPTERA OF THE VORARLBERG. 161 



and this locality, at an elevation of about 6500 ft., must be a 

 very bleak spot during the greater part of the year, for large 

 snow-patches still lay here and there below us, and this delightful 

 day might well have been believed to have been a chosen day of 

 June rather than early August. Here, high above the highest 

 point of the Arlberg Pass, we sat and ate our frugal lunch 

 and drank the water where it bubbled madly out of the groimd, 

 and here among the Brenthids where an occasional Colias palaeno 

 or i'untia callidice crossed oui' path, we spent the loveliest afternoon 

 of the Slimmer holiday of 1910. To see either Brenthia selene or 

 B. eiiphrosipw with wings outspread, on the alpenrose flowers, in the 

 hot early afternoon is a sight not soon to be forgotten. Why 

 Bri'iit/ih selene is one of our favourite species we cannot say, unless it 

 be that the species has always been almost wanting in our collecting- 

 grounds in Britain, but such is certainly the case and probably 

 atibrds the explanation. About 8 p.m. the tall peaks commenced 

 to send their long shadows over the slopes and we began to descend, 

 not before, however, Anthri>cera e.culans and Neinenp/iila /ilnntaiiinis 

 had fallen prey. CrauthKn cnulonelluN and ('. peiieUus were found 

 somewhat abundantly, whilst Acidalia fuinata and Melanippe 

 hastata were also occasionally observed, and Krebia lappona and 

 Melunipiaa epijilinm were frequently noticed as one traversed the marsh 

 to the road, whilst, on the slopes of the mountain on the other side, the 

 latter was seen flying abundantly as we walked slowly back towards 

 St. Anton. Lower down, a single worn ( 'alias In/ale suggested that 

 we were between broods. Over the banks and heather-clad wastes, 

 a little later, Kninielesia adaef/iiota (blandiata) flew abundantly in its 

 quiet manner, the ? s seeking out the eyebright for egg-laying. 



Next morning a walk through the Moosthal was projected, but 

 the weather looked none too promising. Keeping bj' the river, 

 the first waste bank beyond the cottages proved a source of great 

 pleasure. Ant/irocero piirpiiralis was just over, but hundreds of 

 newly-emerged A. lonireiae hung on every blossom, or stood on 

 every upright stem, whilst brilliant A. tranmlpina and A. tiUpt^n- 

 tliilae w'ere also just coming out. Affrlades coridon was in great abun- 

 dance and Ave were able to make observations on the pairing-habit, 

 already published in A Nat. Hist, of the Bntish Butts., iv., p. 88. 

 Hundreds of Chri/soplianiis /lippothoe and a few Heodes einianreae 

 disported on the bank, but the former were very worn the latter quite 

 fresh. Brenthis amatliKsia, too, was abundant, and we observed that 

 Epinephele ianira was just emerging. Both Erehia Wjea and 

 E, euryale occurred on the same ground, a few $ s of the former 

 being of good colour. Anfi/nnis adip/ie was much more abundant here 

 than A. aijlaia, and I'aranie inaera swung swiftly to and fro as it took 

 possession of the waste places on the bank. Hesperia alveus was also 

 common and Tanai/ia atrata {chaerophyllata) hung on the grass blades 

 in great numbers. Hustling into the fiower-heads was Leitcayiia 

 conif/era, at St. Anton, as at Deal or Cuxton, bustling after nectar in 

 the hottest sunshine, Ariria ostrarc/w was also abundant, the spotting 

 on the hindwiag of some specimens of the nbsoleta form, whilst Polij- 

 oiniiiatiis icariis gave a fine lilac-blue 2 , with dark margin to forewing 

 and with orange red spots on hindwings only, a form common 

 enough in England but not so frequently taken in its Continental
