IN THE FRENCH JURA. 51 



hunting ground. By the side of the path which led to the summit 

 Melitcea athalia and a few M. imrthenie were sporting, and a 

 larger insect, which proved to be Satyrus hermione, was flying 

 among the rocks in a quite inaccessible spot, but after the 

 exercise of a little patience it ultimately came within reach of 

 the net. A couple of Thecla spini next fell victims. In a bushy 

 place on the summit A. hyperanthus was much in evidence, and 

 a nice ab. cceca and one or two ab. vidua were added to the 

 morning's bag. A variety of this insect was caught here, which 

 was curiously marked beneath, the one side being spotted as in 

 the type, while the other side was ab. vidua, that is to say, it had 

 three ocellated spots on the left fore wing and only two on the 

 right. Strange to say, I took a similar specimen the next day at 

 Lons. Two Coenonympha iphis were also secured, and a few 

 bright specimens of C. arcania were selected from the numbers 

 which were flying on all sides. After an hour's ramble on the 

 plateau, which yielded only common species, a very rough and 

 precipitous track led me down to the pretty little village of 

 Vaux, a mile or two from Poligny. In the afternoon the slopes 

 on the west side of the valley were visited. The early morning 

 had been bright, but towards noon the sky clouded over, and 

 little was to be got after lunch. On a patch of greensward just 

 above the vineyards a single male specimen of P. hylas was 

 flying with the more numerous P. icarus and C. minimtis ; other 

 butterflies seen during the ramble being P, napi, P. rapce, 

 L. sinapis, V. io, P. atalanta, A. urticcB, P. c-alhum, M. athalia, 

 A. hyperanthus, C. pamphilus, E.jurtina, and P. sylvanus. 



In the evening I went on to Lons-le-Saunier, where I hoped 

 to find some interesting insects, but on the morning of the 15th 

 the meteorological conditions were far from satisfactory. No- 

 thing was flying in the park, nor was anything to be seen on the 

 banks of the little river Valliere until a sawmill was reached, 

 where, flying by the wayside, I took a couple of specimens of 

 Everes argiades. Leaving the water meadows and seeking 

 higher ground I crossed the road and tramway track and found 

 a path which led to the village of Perrigny, where on a railway 

 bank with a sunny aspect I captured Argynnis aglaia, M. athalia 

 and P. icarus, one large male of the latter species measuring 

 34 mm. in expanse. 



Friday, July 16th, was spent at Champagnole, a pleasant 

 town on the sceond plateau, at an altitude of 545 metres. The 

 day was bright but very windy, and it was not until a steep 

 bank by the side of the river was discovered, where shelter was 

 obtained from the breeze, that any butterflies were found. But 

 in this sunny spot they appeared to be all crowded together.
