240 BRITISH BUTTERFLIES. 



In the Isle of Sylt, in the North Sea, it occurs everywhere on dry, 

 heathery, and sandy wastes, whilst in Denmark it occurs everywhere 

 on heaths and mosses. In Hanover, it frequents heaths (Glitz), and 

 meadows (Peets), whilst, in the Rhine Provinces, the heaths of 

 Hilden, Krefeld, etc., are particularly noted. In Anhalt, it occurs on the 

 heaths and in the forest openings of the Mosigkau Haide, the banks of 

 the railway (Amelang), the meadows of the Hirtenhau, but, at Wornitz, 

 in a sandy district, covered with pines and overgrown with heath, at 

 Brachmeierei, its habitat is a more open sandy heath-covered place, 

 with quite young pines (Gillmer); in Brunswick it is very common on 

 heaths (Heinemann), and, in Silesia, it chooses dry stony localities in the 

 Trebnitz mountains, but in the plain and on the low foothills, it chooses 

 dry heaths (Wocke). It is also noted as being especially abundant on 

 heath in the Kingdom of Saxony (Steinert), and Saxonian Upper Lusatia 

 (Schiitze). In Bavaria it prefers the borders of forests overgrown 

 with heath and broom (Schmid), but also affects pastures on gravelly 

 soil, with sunny position and sparse vegetation (Kranz), whilst it is 

 noted as occurring in meadows at Kempten (Kolb). In the Bavarian 

 alps, however, it occurred abundantly on an extensive sandbank thrown 

 up by the river near Oberstdorf, and overgrown with willow and other 

 bushes, in company with Plebeius avgyvognomon, Cupido minimus, 

 Lycaena arion, Cyanivis semiargiis, Agriades bellavgus, Polyommatus 

 irarus, etc., whilst, at the junction of the Oy and Trittach, two fine 

 mountain torrents, a sunny bank was alive with butterflies, 

 among which Plebeius aegon was found with hycaena avion, Chvyso- 

 phanus hippothoe, etc. (Dadd). In East and West Prussia it is said to 

 prefer meadows and woods (Speiser); in Hesse, wood-clearings, but is 

 especially abundant in the clover-fields and meadows of the Niedgau 

 (Koch), and in open forest land and pastures, specially choosing open, 

 grassy, and flower}'- pastures, meadows and clover-fields at Darmstadt, 

 etc. (Glaser); atWaldeck it haunts grassy, flower-covered slopes (Speyer). 

 and, in Thuringia, is found in the forest glades of Gera, and the open 

 heaths in the forest near Ossig, etc. (Wilde). In Brandenburg it is said 

 to haunt meadows (Kretschmer), and wood-clearings (Herrmann); at 

 Bernau, it was found commonly on a piece of waste ground covered 

 with thistles, near to which the heather was just commencing to bloom, 

 in company with Plebeius argyrognomony Heodes vivgauveae, Loweia 

 dorilis, Rumicia phlaeas, Adopaea flava, A. lineola, etc. (Dadd), whilst 

 in Posen it is said to choose forest glades and fields (Schultz). In 

 Baden, it is abundant in the plains around Lahr, and especially so on 

 the banks of the Rhine (Keynes). Gillmer further notes that, in 

 Anhalt, the moorland form of the species is rare, the heath form 

 abundant, the latter flying in the paths of the sandy heath and pine- 

 woods, at the time that ( 'alluna vulgaris forms a very fine covering of 

 green herbage ; it appears to be remarkable that the heath form does 

 not extend into (or even fly into) the grassy and moist parts of the 

 woods in the neighbourhood. In Austria, it is reported as occurring 

 in meadows in Bohemia (Nickerl), in almost all wet and marshy 

 meadows in Salzburg, as well as the Leopoldkron peat-bogs, and the 

 Sdllheim moss (Richter); it appears to occur everywhere in the 

 mountain valleys of the Tyrol, as high as the woods extend, occurring 

 on the valley slopes, as high as Franzenshohe in the Trafoi-thal; 

 whilst we found it on the slopes of the Mendelstrasse, up to the Mendel-
