142 BRITISH BUTTERFLIES. 



(Fox), and in the woods of the Llandudno district (Harding), but at 

 Stockton, about eight miles from Eugby, it is again reported as being 

 found in a chalk-pit where Anthyllis grows in abundance (Garrett). It 

 abounds at the end of June, at Black Head, in county Clare, on the 

 horizontal limestone slabs, sometimes at the very edge of the cliff, 

 where nothing much grows, except its foodplant and a few stunted 

 tussocks of grass, the rare Adiantum capillisveneris, Saxifraga 

 hypnoides, S. tridactylites, and the lovely fragile Geranium sanguineum 

 (Lawless); near Gal way it occurs on the railway-banks (Walker), but 

 also on the coast sandhills of Sligo (Russ), and is said to be especially 

 abundant on the Portmarnock sandhills (Birchall), whilst it also occurs 

 freely on the coast hills near Belfast (Barrett). It occurs freely on St. 

 Cyrus' cliffs, north of Montrose, and is generally common (Duncan); 

 but on the banks of the Lochay, in Perthshire, is found most 

 abundantly on a small sandy flat (Morton). With regard to its 

 excessive localisation, Barrett observes that it loves warm hollows and 

 sheltered spots, such as old chalk-pits, limestone quarries, etc., 

 occurring year after year, commonly, in exactly the same spot of a few 

 square yards in extent, though, perhaps, hardly to be found elsewhere 

 for miles around ; on the warm slopes of the chalk-hills of the 

 southern counties, however, it is very generally distributed, though 

 even here it will resort to any slight ditch or hollow full of flowers, to 

 the exclusion of the surrounding more open ground. Its habitats on 

 the continent are exceedingly variable. It is found almost throughout 

 Belgium, but more especially in the limestone regions, preferring 

 elevated meadows, or the dry and arid slopes of embankments of rail- 

 ways, etc. (Lambillion). It occurs in the northern part of France in 

 localities quite similar to those in Britain, but, in the south of France, 

 its localities are especially varied. At Remoulins, it is to be found in 

 April, flying in the glades and open spaces among the tall bushes that 

 clothe the slopes, near the Pont du Gard, among swarms of Scolitan- 

 tides baton, Aricia astrarclte, Polyommatus icanis, Leptosia sinapis, 

 Euchlo'e cardamines, E. eiiphenoides, etc. At Gresy-sur-Aix, it loves 

 the corners of the meadows on the edge of the bush-covered slopes, 

 whereswarmsof Melitaeas — M. didyma, M. phoebe, M. parthewie — Brenthis 

 dia, A(/riades bellargus, etc., abound ; at the top of the Col de la Faucille,. 

 it haunted a meadow with Brenthis ino, Erebia euryale, Adsn'ta yen/on,. 

 etc., whilst at Chavoire, it was found with Lycaena aHon, Everes 

 arijiades, and swarms of Thymelicus acteon, on the grassy banks edging 

 a lucerne field, just overlooking the lovely Lac d'Annecy. At Megeve 

 it preferred a splendid upland meadow, swarming with most of the 

 subalpine species of the district, which swing in abundance from the 

 wealth of wild-flowers growing there. In the Alpes-Maritimes, 

 Millie-re says that it inhabits dry woods and hillsides. At Digne, it 

 was discovered on the edges of the steep flowery gullies that discharge 

 their streamlets into the Eaux-Chaudes, whilst, at Abries, it occurred 

 at 6000ft. elevation by the wayside with Cyaniris semiargus, Klugia 

 ('/'/weld) s/iini, Loweia <i<>rd;us, etc., as well as on the upland 

 pastures, far above the larch forest, on the way to the Pointe de la 

 Lauze, among a strange mixture of lowland and subalpine species, as 

 well as on the topmost slopes of the Crete de Reychasse. It was also 

 very abundant on one great flowery slope leading up to a high, rounded 

 knoll above Le Lautaret, at fullv 8000ft. elevation ; and, here, some of the
