220 THE ENTOMOLOGIST. 



vanadia occurs practically at sea level in the high North at Alten 

 (Bossekop), whence I have examples taken by Dr. Chapman at 

 the end of June and the beginning of July, 1898. Tutt (' Ent. 

 Eecord,' xvi, p. 240) mentions the two taken on the same tlay on 

 the Col du Torrent in the Val d'Herens region of Switzerland, 

 but does not specify their actual coincidence. Above Abri^s, Htes.- 

 Alpes {op. cit., xii, p. 260) he found achillea only, exalans being 

 entirely absent on all the higher slopes. 



I note too that, though in my experience achillece in the 

 Pyrenees haunts the foot-hills and lower elevations ns a 

 rule, and exulans does not begin below 1600 m. with anthyUidis,^ 

 another member of Hiibner's Lycastes group, certain " omnibus " 

 localities are given by M. Rondou, for example, without informa- 

 tion on the point at issue, viz. whether the two make contact. 

 In the Spanish peninsula our collectors, including Mr. Sheldon, 

 have taken it as far south as the Albarracin Sierra, and Dr. 

 Chapman at Tragacete. In Italy it seems to reach its limit in 

 South Latium, where, writes Conte Emilio Turati (' Lepid. 

 Comparee,' fasc. vi), " The only locality where we have found 

 it is at Fraine and the valley of the Petrella in the Aurunci 

 Mountains. It flies little, preferring to remain quietly sucking 

 the flowers. The variation of this species is limited to the 

 extension, more or less pronounced, of the spots on the fore 

 wings or their confluence. The majority are to be found at^the 

 end of June. We have never succeeded in finding the larva." 



That achillece and exulans do overlap in certain alpine 



locahties I have now incontestable authority, thanks to the 



kindness of Dr. J. L. Reverdin, who, with his invariable courtesy, 



has answered my question definitely in the affirmative. " I seem 



to remember having seen the two together," he writes, " but 



M. Rehfous" — one of the most accurate observers of Swiss 



Lepidoptera— " states that he saw the two species flying together 



at 2000 m. in a localit^^' in the Sixt Valley, Hte.-Savoie, on 



July 1st, 1916, and at Findelen, near Zermatt, on July 15th, 1911. 



From the southern area of the Balkans I have quite typical 



examples captured by Lieut. P. J. Barraud near Salonika. The 



Natural History Museum series includes a few from Greece from 



the Leech collection, the exact locality of which is not specified. 



In the French, Swiss and Austrian Alps it is one of the 



commonest Anthrocerids, and I found n brilliant form flying 



over the dry grassy slopes of the mountains round Herkulesbad, 



which delightful entomological hunting-ground apparently falls 



to Rumania under the treaty of Versailles. In southern Russia 



the form appears to include helliii.^ Mr. Sheldon (' Entomologist,' 



xlvii, p. 317) says all Zyga3nidae were very rare at Sarepta when 



" This is the form described by Staudinger as " Major, ohscurior,'' but M. Dupont 

 says the variation consists in the median upper spot of the fore wings (spot 3) being 

 cut in two by a stout nervure.
