THE LEPIDOPTERA OF THE VORARLBERG. 149 



Aberrations of Senta maritima (in'tli plate). 



By H. M. EDELSTEN, F.E.S. 



The interesting specimens of Senta inaritiina exhibited in plate vi 

 were taken in the Isle of Wight last August by Messrs. Prout and 

 Capper. The photograph shows clearly the peculiarities of the first 

 and second specimens. The third specimen is a combination of the 

 aberrations bipnnctata and nii/rostriata. I have only once seen another, 

 and that was taken in the Norfolk Broads. Mr. Capper suggests the 

 varietal name of combinata for this form. The date of capture, 

 August 9th, seems to me to be exceptionally late for the species, 

 though Mr. Prout tells me they took a good number. I have always 

 looked on it as being over by July 20th, though I once took an odd 

 specimen on July 31st. Mr. Tutt says that on the Cliffe Marshes he 

 considered it a June rather than July insect, and that August appears 

 to him also to be remarkably late.

The Lepidoptera of the Vorarlber^ — St. Anton and the Arlberg Pass 



— the Moosthal. 



By J. W. TUTT, F.E.S. 

 The tourist entering the Tirol, and approaching Innsbruck, its 

 capital, by train, does so by the Arlberg route, leaving the main 

 Ziirich-Engadine line at Buchs, and crossing the valley of the Rhine 

 into the Vorarlberg, as far as Feldkirch ; here the valley of the 111 

 is entered, the route passing along the valley as far as Bludenz, 

 where it diverges into the Kloster-thal watered by the Alfenz, 

 which it finally crosses above Langen, plunging into the Arlberg 

 tunnel, somewhat over 6J miles long, emerging on the other 

 side at the little village of St. Anton, the highest in the Rosanna- 

 thal, and beautifully situated ; the part of the valley above the 

 village is known as the Fervall-thal, and below it the Stanser-thal. 

 The village is surrounded by moderately high mountains and the 

 country around is all good butterfly -ground, although the weather 

 would not let us fully test it in this direction. Arriving there about 

 noon on July 30th, a glance round at the end of the afternoon promised 

 well, as there seemed an abundance of species quite near the village, but 

 the sun soon went oft' the banks and the butterflies, as usual, disappeared 

 as by magic ; the next day the 31st was dull and chill and a long swinging 

 walk up the Arlberg road was the best thing that could be done, but 

 the morning of August 1st broke delightfully warm with a delicious 

 air that set every fibre of the body on the move. A fairly early start 

 was made for the summit of the Arlberg and ere long the net was 

 occasionally and usefully at work. In the pinew'Ood some few kilo- 

 metres above the village, Erehia liijea was in good condition, but many 

 Aporia crataejii produced nothing better than worn ? s, the centre of 

 the wing nearly or quite transparent, whilst from the rocks Daaydia 

 obftiscata flew off in abundance. Eubolia niensnraria was equally com- 

 mon, and on the pine-trunks a fine banded race of Larentia caesiata was 

 not at all infrequent. A few worn Pleheiic^ onfiia (aei/on) showed that 

 this species was over, whilst a quite hopeless specimen each of Heapcria 

 July 15th, 1910.
