as occurring in Mecklenburg, in the wood near Kleinen, in places 

 where blackthorn bushes are abundant, whilst Tessmann notes it as 

 occurring on the blackthorns by the road to " Fuchsberg " ; in the 

 Ehine Provinces, Stollwerck records it as occurring chiefly in the 

 clearings of woods, although, at Trier, it is found occasionally in 

 gardens. Bossier observes that, in Nassau, the species continually 

 gets rarer because of the continual uprooting of the blackthorn, the 

 species also being apparently confined to very warm slopes, outside, 

 and not in, the woods ; Gillmer, however, says that he took the butter- 

 fly here, on the sloe bushes growing by the side of the. wood-ridings, 

 as in Anhalt and Mecklenburg, i.e., quite in the woods, whilst at 

 Heidenheim, in Wiirttemburg, it also chooses sunny wood-ridings, 

 (Loffler). In the Wisper district, where the species is sometimes 

 very common, Fuchs says it prefers hedges to trees, and the neigh- 

 bourhood of villages to more secluded places ; whilst Glaser observes 

 that, at Giessen, etc., it chooses hedges and gardens, and visits the 

 bramble bushes when in flower. Siegel says that, near Giessen, he 

 has only noticed it on the outskirts of woods, or in woods in places 

 exposed to the sun ; Vigelius, too, notes it as occurring in the gardens 

 of Wiesbaden. At Zeitz-on-the-Elster it chooses wood-clearings 

 (Wilde) , and, at Halle, is found in gardens, and woods of deciduous trees, 

 where blackthorn grows (Stange), whilst in the Mosigkauer Haide it 

 haunts the blackthorns in great numbers (Amelang), and is found in the 

 forests of Klein-Zerbst and Diebzig (Gillmer) ; in the Harz district it 

 only occurs in the low foot-hills (Speyer). At Potsdam it is recorded 

 from gardens, and also in gardens on the outskirts of Frankfort-on- 

 Oder. In Silesia it rarely goes into the mountains, its haunts in the 

 plain being pretty generally distributed wherever blackthorn is found ; 

 similarly in Baden, it is recorded as occurring only in the plains and 

 lower hills, not ascending into the mountains (Meess and Spuler), and 

 being especially abundant in the Durlach Wood (Gauckler); near Lahr, 

 Keynes found the species abundantly close to the Ehine, haunting a 

 tract of privet-bushes in bloom, on the flowers of which they sat in 

 scores, whilst at Freiburg-in-Baden Lowe says it prefers hedges of 

 mixed growth, showing a marked liking for flowers of bramble and 

 Clematis vitalba. In Alsace, clearings of woods, where it loves to rest 

 on the bushes, are most frequent, whilst it is also found by the sides of 

 the canal at Mulhausen ; the roads near the Semmwald, the road leading 

 to the forest of Bouxwiller, and the outskirts of the woods of Voipy, 

 near Metz, are also noted as habitats of this species. In Mecklenburg, 

 Busack notes the wood of Mestlin as a good locality, whilst Loffler, as 

 already noted, says that, in Wiirttemburg, sunny paths in woods provide 

 the best localities. In Bavaria, Maassen took it on the Altenberg, near 

 Kissingen. In Austria, it is reported in the gardens of Bohemia and 

 Moravia (Nickerl) ; in fruit-orchards, gardens, and along blackthorn 

 hedges, throughout Lower Austria (Kossi) ; in orchards, and by the 

 edges of fields, among blackthorn bushes, but only in the plains, or on 

 quite low hills in Salzburg (Richter), and in fruit-orchards, flying around 

 plum-trees in the Lavantthal and Mollthal (Hofner), etc. In Hungary, 

 Aigner-Abafi says that it is generally rare, and is found flying around 

 trees of Primus domestica and P. spinosa, and is specially attracted by 

 bramble-blossom. In Roumania, it is reported by Caradja as occurring 

 in gardens and in woods, locally, in several places. In Switzerland,
