Tambov; in the extrême south-east in Kherson, and at Taganrog 

 — apparently isolated localities which suggest that the species 

 hereabouts may be a form of C. syniphita, this Cœnonympha 

 seemingly taking the place of tiphon in some parts of the western 

 palaearctic région. 



In Rumania, von Caradja announces tïphon from the upland 

 moors of Tschachleu {Die Gros:sschmet. des Kong. Rumanien, 

 " Iris ", Dresden, VIII, p. 59), and Hormuzaki from the Bucovina 

 border-land. In Hungary, the late Abafi Aigner records it from 

 Debréczin, Rév (Comté de Bihar), Eperjes, and Mehadia. 



Von Rottemburg, as has been stated, described this species from 

 spécimens taken in the neighbourhood of Halle. Later authorities 

 report the typical form on moors and mosses practically across 

 Germany from Schwerin in the north to Dresden in the south, 

 and down through the Black Forest to Constance; east from 

 Belgium, Saint-Hubert, Hautes-Fanges (" fort localisée ", Donckier 

 de Donceel), and the Netherlands, Drenthe bei Hoogvene, and 

 Utrecht, bei de Bildt (P. C. Snellen), to west-central Russia. 

 In Switzerland, as might be expected, it abounds chiefly in the 

 lower marshes, e. g., Stâfa Bog, Schiipfen, Val de Travers, Gimel- 

 sur-Rolle, and Schaffhausen; the southern Swiss limit to the east 

 being apparently in the Weesen Marshes, where many English 

 collectors hâve taken it of récent years; and in the Eastern Alps 

 from the Vor Arlberg (Elwes) to Brixen and Krainberg. In 

 the north-west, it is reported (typical) from Divonne, and Le 

 Brezon; and in the centre it appears to reach its highest altitude, 

 and furthest south on the Spliigen where I observed it near Andeer 

 on July 5th, 1900. But, though it has been found at Leuk, and 

 probably will be discovered in the marshes of the foothills on 

 the left bank of the river, it does not appear to hâve extended 

 to any great distance south of the Rhône valley. 



In France, as M. Oberthiir tells us {Etudes Lépid. comparée, 

 fasc. IV, pp. 49-52), tiphon is a rare butterfly confined to the 

 eastern and north-eastern departments; for example, the Doubs, 

 at Morteau; while it was abundant in the summer of 1866 in the
