96 BRITISH BUTTERFLIES. 



daplidice, Callophrys rubi, Melitaea cinccia, Colias hyale, etc., also that it 

 occurs on some rough dry slopes on the sides of the Vitoch, a granite 

 mountain 6000ft. high, due south of Sofia ; whilst near Slavisch Brod, 

 it haunts the Save marshes, in company with Chrysophanus dispar var. 

 rutilus. In Belgium, it appears to be very local, and largely confined 

 to limestone districts, e.g., on the limestone rocks near Namur (Polet); 

 on the "racecourse du Prince ". opposite Colonster (Donckier); but 

 in the woodland glades of the Grand Duchy (Dutreux). In France it 

 occurs in fields and in wood-clearings, not being rare even in the 

 neighbourhood of Paris (Godart); in the fields and pasturages on the 

 outskirts of woods in Doubs (Bruand); in the dept. Saone-et-Loire, it 

 flies strongly in fields of lucerne and trefoil (Constant). In Brittany, 

 on the landes of Monterfil, in July and August, when the ling is very 

 tall, the imagines flyover the tops of the ling, yet it is to be noted that, 

 although the specimens of the summer brood fly in this habitat, those 

 of the spring brood inhabit the damp meadows and grassy rides of the 

 woods in the neighbourhood, the summer brood being much more abun- 

 dant than the spring brood ; whilst at Angouleme it is found in lucerne 

 fields at the end of July (Oberthiir). In the south of France, the 

 species occurs regularly in August in a warm, sunny, corner of alarge 

 field allowed to run to waste, on the upper edge of the scrub that 

 covers the hills above Gresy-sur-Aix ; this little spot which is about 40-60 

 yards long, and 10-20 yards deep, rather grassy, with some tall bushes 

 of lucerne, and here and there a walnut tree, is a favourite corner of 

 this species, where it flies with swarms of Erebia aethiops, Satyrus 

 hermione, Hipparchia briseis, Enodia dryas, Argynnis adippe, Dryas 

 papliia, Colias hyale, O. edusa, Brenthis dia, Melitaea didyma, M. par- 

 thenie, M. phoebe, Polyommatus icarus, P. hylas, Cyaniris semiargus, 

 Aricia astrarche, Agriades bellargus, A. corydon, Melanargia 

 galathea, and swarms of other species ; it also occurs on the edge 

 of the field near by, which usually has clover growing in it. In 

 another Savoy locality, a very large form of the species was found at 

 the end of July, 1902, on the edge of a lucerne field that slopes up from 

 the Lac d'Annecy near Chavoire. At Digne it haunts the well- 

 known little lateral valley, with a streamlet for a path, that runs into 

 the Eaux-Chaudes, above "the Baths," occurring there (possibly as a 

 third brood) in mid- August, 1906, and, at the end of April, 1897 

 (possibly as a first brood), whilst Gurney observed it there in mid- 

 June, 1907, flying in company with Cupido zebras, Leptidia duponcheli, 

 Loweia dorilis, etc. Jones observes that, at Biarritz, the typical form is 

 common in August, flying near the sea, over heathy ground, whilst he 

 also observed it at Pierrefitte-Nestaias at 1665ft. elevation ; and Sheldon 

 records that, near Guethary, it inhabits a series of small swamps and 

 wooded hollows, flying in mid-July and August, with Lampides boeticus. 

 In the north of Italy its habitats are varied. Lowe states that on Monte 

 Bre he found only E. alcetas (coretas) at the summit on June 13th, 1903, 

 whilst on July 29th, 1904, lower down on the same mountain, he 

 found only typical K. argiades. Behind Susa we found the species 

 going over in mid-August, 1897, in a lovely little wooded gorge, where 

 Lampides boetieus was not uncommon, and, at the end of July, 1894, on 

 the slopes just above Courmayeur. Tetley disturbed some $ specimens 

 on a dull day in August 1905, on the edge of a field off the road between 

 Chiasso and Como, close to the lake, the field growing some species of
