and Switzerland, where its foodplant grows (Speyer). It is recorded 

 as occurring throughout the oak-woods of Hesse, being particularly 

 abundant in the " Stadtwald " at Frankfort-on-Main (Glaser), in most 

 of the oak-woods of Pomerania (Hering), Mecklenburg (Schmidt), 

 Hanover (Glitz), the plains of Silesia (Wocke),the kingdom of Saxony 

 (Schutze), Bavaria (Kolb), Posen (Schultz), and the lowlands of Baden, 

 extending into the foothills and lower mountains (Meess and Spuler). 

 It haunts sunny hillsides timbered with oaks in East and West Prussia 

 (Speiser), the hedges containing oak-trees by fields and meadows, as 

 well as the oak-woods in Holsatia (Laplace), the oak-scrub, and woods 

 of deciduous trees on the foothills and lower parts of the Trebnitzer 

 mountains, rarer in the woods of the lowlands of the district (Doring), 

 but also occurring not rarely in all the oak-woods of the plains of 

 Silesia (Wocke). It also occurs on the tall oak-trees on the summit 

 of the Neuenahr (Maassen), in parks, flying high around the tall oak- 

 trees, in the Bhine Provinces, especially abundant on the right banks 

 of the Rhine, near Cologne, and in the forests of Kuppersteg, as well 

 as in almost all woods consisting of deciduous trees near Elberfeld and 

 Barmen (Weymer), abundant in all the oak-woods of Hesse (Schenck), 

 especially abundant in the "Hinterland," and on the Winterstein near 

 Friedberg (Glaser), the oak-forests of Thuringia (Krieghoff), prefers 

 the clearings in the oak-woods of the province of Saxony (Wilde), and 

 distributed throughout the oak-forests of the kingdom of Saxony (Ent. 

 Ver. Dresde?i) ; in Anhalt and the Hartz mountains it occurs in all the 

 oak-forests, abundantly in the Mosigkauer Haide, the clearings in the 

 forests of Anhalt, etc., swarming in some years in the forest of Klein - 

 Zerbst (Gillmer), also occurring in all the oak-woods of the north- 

 eastern border of the Hartz (Reinecke), and the foothills of the 

 Wernigerode district (Fischer). In Switzerland, it haunts not only 

 the oak-woods, but copses and oak-scrub growing on the lower 

 slopes of the mountains ; Blachier notes it as occurring in oak- 

 woods in the neighbourhood of Geneva, and also in a wood of 

 mixed growth at the foot of Mont Saleve ; Frey says that it occurs 

 throughout the country on oak, and up the mountains to the elevation 

 that the tree grows, being sometimes common, at other times rare. 

 In Austria, it occurs in the oak-forests of Bohemia (Nickerl), and of 

 Lower Austria (Rogenhofer), in the glades of the oak-woods of southern 

 Moravia (Schneider); in Upper Austria it is somewhat rare, but rather 

 more common in the lowlands (Himsl) ; in the Tyrol, too, it appears 

 not to go up any distance into the mountains (Weiler). Eversmann 

 says that it is not rare among hazel and oak in the Russian provinces 

 of Casan, Orenburg, Saratov and Sarepta, where it is apparently 

 getting towards the eastern limit of its range. It occurs throughout 

 the Baltic Provinces wherever oak occurs, particularly in woods of 

 deciduous trees, and on the outskirts thereof, flying rather high up 

 around the oak-trees (Nolcken). Speyer says that it is fairly common 

 in the south of Scandinavia and the centre, at least as far as 

 Stockholm. 



British localities. — Distributed throughout, in oak-woods, from
