LÉPIDOPTÉROLOGIE COMPARÉE 167 



ocellation on the under side of the hind wings. And, as the 

 Scandinavian entomologists hâve sunk Lus in lûidion, it surely 

 would be as well to follow thcir example, if only to avoid that 

 multiplication of named variations which is the bane of our 

 systematics. 



Herrich-Schaeffer's Satyriis isis {Papil. Euro p., PL 61, figs. 293- 

 296) is a butterfly ihe colour of which in both sexes, upper and 

 under side, does not differ materially from that of many Scotch 

 laidion. Except for the small black apical spot on the upper 

 wings of the female, and a trace of the same on the under side of 

 the wings of the maie, there are no ocellations of any kind. 



CONTINENTAL DISTRIBUTION 



According to Staudinger Tiphoii is distributed in the western 

 palaearctic région as follows : 



var. (et ab.) Phïloxenus -. north-west Germany; north of 



England. 



var. Laidion (=^ Scotica, Stgr.) : Scotland; Ireland — transitional 



form. 



var. (et ab.) his -. north, and arctic Scandinavia, 



and Russia; Alps of Hungary ; 

 part of the Central Alps. 



I am not concerned with the Asiatic forms further enumerated 

 in the Catalog of 1901, and I hâve shown, already, that the 

 invention of scotica is gratuitous, and apparently without warrant. 



In his Fortegnelse over N orges Lepïdoptera, Herr W. M. Schoyen 

 limits the range of Cœnonympha liphon (" cum var. laidion ") — 

 without mention of var. isis — ■ between 59° 30' and 64° 30' N. lat. ; 

 that is to say, within the provinces of Smaalenene, Akershus, 

 Hedemarken, Buskerud, South-Bergenhus, South-Trondhjem, and
