118 BRITISH BUTTERFLIES. 



whilst Fritsch notes that specimens have been taken from March 31st- 

 May 19th, the latest recorded appearances being June 3rd-13th. In 

 the Tyrol, the dates vary tremendously — at Bludenz, March 12th-May 

 10th ; at Bregenz, as early as March 28th ; at Innsbruck, February 

 23rd-April 15th ; whilst in the Val Fondo, Wheeler notes it as con- 

 tinuing into July. Hofner distinctly states that there are two broods in 

 the lowlands of Carinthia, the first from April till the beginning of June, 

 the second in July and August, but only one brood in the mountains in 

 June and July ; but Fritsch simply gives as actual dates April 4th-May 

 8th, at Hausdorf ; and April 18th-May 7th, at St. Jakob. Zeller also 

 notes it as abundant towards the end of May, at Coritenza, and Mann 

 only gives it as single-brooded in Carniola, from beginning of May till 

 the middle of June. Kroulikowsky says that, in the Kasan district of 

 Kussia, the earliest specimens are seen about the middle or end of 

 April, and the latest disappear about the beginning of June, and 

 in the Wiatka govt, it appears in May ; Bartel also gives May for 

 the southern Urals. Nolcken notes that, in the Baltic provinces, it 

 appears in early years in April, but is abundant in May, occasional late 

 specimens lasting until June. In Bulgaria, in the neighbourhood of 

 Sofia, it occurs in May, according to Bachmetjew; whilst Rebel says 

 that throughout Bulgaria, Bosnia, and Hercegovina, the insect is 

 double-brooded, but only notes it as occurring from mid- May to early 

 July ; whilst in Roumania, Caradja says it occurs from May to August 

 in one continuous brood, which is what one suspects to be true of the 

 adjacent countries. The following actual dates may prove interest-
