the town of Stavenhagen, on Populus tremula, somewhat commonly. 

 Bossier, like Voelschow, thinks that the species is much overlooked in 

 Nassau, because of its retired habits, although it is found in the 

 plantations, near the "baths," at Wiesbaden; whilst, at Cassel, 

 Borgmann says that it occurs on' the elms of the " Easenallee," where 

 this avenue crosses the " Lindenburg." In the Province of Saxony, 

 it occurs on the northern slope of the " Steigerwald," in the woods of 

 deciduous trees in the Saale Valley (Stange), whilst at Dessau, it also 

 occurs in the woodlands (Kichter), and in parks (Amelang). In Silesia, 

 it is found in the foothills and lowlands, in bushy places, but is usually 

 rare, although widely distributed (Wocke). In Bavaria, it occurs in 

 the " Wolf schlucht," at Regensburg (Gillmer), and in the " English 

 Garden " and the " Dachauer Moss," near Munich (Kranz). In 

 Baden, it is distributed over the west side of the Schwarzwald, and among 

 the foothills and on the plain, in woods of elms, lime, oak, etc. (Meess and 

 Spuler), whilst Keynes notes that, near Lahr, the species occurs on a 

 tract of low-lying land near the Rhine, the imagines frequenting the 

 blossoms of some low privet bushes in June. In Alsace, it occurs in 

 the woods of the plains only (Speyer). In Austria, the species is 

 largely confined to the plains and lower valleys, e.g., in Moravia, it is 

 pretty common in the wooded pastures of the south (Schneider) ; 

 whilst, near Vienna, it occurs among elms in the "Prater," the 

 " Augarten " (Rossi), in the district above the " Wienerwald " 

 (Schleicher), etc., whilst, in Salzburg, it appears to be very rare, 

 occurring in few places, e.g., the foot of the " Kuhberg " (Richter) ; 

 it is also very rare in the Tyrol, and again, only at low elevations, e.g., 

 the " Gugler Garden" at Botzen (Hinterwaldner), in the Val Popena, 

 in the Dolomite district (Mann), and at quite low elevations in the 

 Innsbruck district (Weiler). It appears to be equally rare in Carinthia, 

 where it has been taken in the Lavantthal and the Mollthal (Hofner). 

 In Hungary, Aigner-Abafi says it is distributed throughout, but rather 

 rare, although, in some years, occurring more commonly, being particu- 

 larly attracted by the blossoms of Sambucus ebulus when growing near 

 elm-trees. In Britain, it is generally assumed to be a woodland species, 

 and the assumption is, in the main, accurate, although parks, avenues, 

 hedgesides, gardens, etc., often give home to the species. Thus we 

 find recorded — the ridings, clearings, and outskirts of Chattenden 

 Woods (Tutt); generally distributed in the woods on the hillsides in 

 the neighbourhood of Stroud (Davis) ; the outskirts of woods, and 

 the borders of the rides of woods at Wellington, Somerset (Milton) ; 

 occurs freely in a wood near Lincoln (Pearson) ; in the clearings of 

 Monk's Wood (Westwood) ; in Cowleigh Park, and in the Trench and 

 Warndon Woods in Worcestershire (Edmonds) ; in woods, chiefly 

 composed of beech, but among which wych-elms grow, at Marlow 

 (A. H. Clarke) ; in the w T oods of the Doncaster district (Brooks) ; 

 occurs freely in a wood, quite close to Taunton, in which a number of 

 wych-elms grow (Doidge) ; on tbe edge of a wood at Cwrt-yr-alla 

 (Shelley) ; in Savernake Forest (Alderson) ; throughout the woods of 

 North Lincolnshire (Simmons) ; in the woods at West Wickham 

 (Sheldon) ; in a clearing in a wood near Box Hill (Turner) ; plentiful 

 on the wych-elms on the south side of Box Hill (Oldaker) ; in woods, 

 near the coast at Cowbridge, on blue lias, the country it frequents 

 having a generally damp climate (W. E. R. Allen) ; in a wood, border-
