Time of appearance. — The species is double-broodecl in its more 

 northern, and triple- or quadruple-brooded in its more southern, 

 European habitats. At Glogau, Zeller repeatedly obtained eggs in 

 July and August, but the larvae always hybernated when fullfed, 

 pupating in the spring ; on the contrary, eggs from £ s taken near 

 Biarritz on July 24th, and reared in England, produced, without excep- 

 tion, imagines between September 6th and 18th, 1904, none going over, 

 thus suggesting an extra brood as between Silesia and southern France; 

 at Guethary, Sheldon noticed an assumed second-brood worn on July 

 14th, 1905, and a quite new brood fully out in the same place, August 

 8th-12th; this, no doubt, corresponds with the seeming third-brood 

 that appears at Gresy-sur-Aix, in varying seasons between mid- August 

 and the end of that month. Usually the spring examples are smaller 

 than the summer brood, the autumn brood being a mixture in size of 

 large and small examples. In Belgium it seems to be double- brooded, 

 appearing somewhat earlier or later according to the season, the first- 

 brood from the end of May and throughout June, the second-brood 

 from August until the end of September (Lambillion), although Hen- 

 nin notes its appearance in July at Virton and Denee. In the Nether- 

 lands it occurs in May and July (Snellen). In France it is rare in 

 May and June, more abundant in July-August, e.g., in the forest of 

 Amboise (Lelievre), Brenne (Martin), Nohant (Sand), in Brittany 

 (Oberthur), Mont Dore (Sand), Allier (Peyerimhofi"), Chavoire, Gresy- 

 sur-Aix (Tutt), etc ; the second-brood is very abundant in the Vosges 

 Dept. — July lOth-August 2nd, 1908 (Gibbs). It is reported as triple- 

 brooded in the Alpes-Mari times (Bromilow), whilst Rondou notes it 

 in the Pyrenees from June- September, and Goossens as occurring fre- 

 quently in September, near Grenoble, and one suspects that it is at least 

 partially triple-brooded in all the warmer parts of southern France. 

 Chapman notes it as early as March, 1897, near Cannes. Many author- 

 ities give only July-August for central and northern France, but one 

 suspects that the possibly rarer first-brood has been in these cases over- 

 looked; whilst as far north as Coted'Or, evident third-brood examples 

 were taken, September 3rd, 1905 (Rehfous) ; and Guenee notes that it is 

 occasionally found at Chateaudun, in September and October. It has 

 been noted as occurring in May in Corsica (Mann), and on July 13th, 

 1905, at Corte (Powell), apparently the only summer record, a very 

 strange fact, as our collectors should have met the later broods. In 

 Switzerland, it occurs in the Geneva district from the end of April- 

 June, and then, almost continuously, from the end of July to early 

 September (Blachier), the latter consisting possibly of a second- and a 

 partial third-brood (Reverdin). Two broods are recorded from the 

 Zurich district by Frey, and Lang mentions the August brood on 

 Mt. Pilatus and at Meiringen, and one suspects the occurrence of at 

 least a partial third- brood in all the warmer parts of Ticino. In 

 Germany the species is suggestively partially triple- brooded in the 

 Rhine Provinces, occurring in May and July and September (Stollwerck), 

 but otherwise noted as double-brooded in East and West Prussia, end 

 of April to beginning of June, then again mid-July to September 

 (Speiser); in Pomerania, at the end of May and again in July (Hering); 

 in May and July in Hamburg (Zimmermann) ; in Hanover,
