200 Mr. H, J. Elwes on the 



I have seen no similar females of cinpliron from any place 

 except two in Grum's collection marked " Alpes/' wliicli, if 

 they do not come from Bulgaria, I am inclined to refer 

 to cemc. T caught cemc females at the same time and 

 place flying with their males in compan}^ with cpipJiroiif 

 and can easily distinguish them by their large size and the 

 broader, more rounded wings, and, as I have shown below, 

 this form of ceme is different from the Alpine or Pyrenean 

 one. 



87, 88. E. nieditsa, ¥., and var. psodea. Hub., and E. ceme, 

 Hub. var. 



Though these species were xevy abundant in the 

 Rilo Dagh I have very great difficulty in deciding how to 

 name many of the specimens, of which we took large 

 numbers. 



The form of medusa which Mrs. Nicholl took at Slivno 

 in the early part of the season is a large form with large 

 ocelli, usually five in number on the fore-wing, of which 

 the third is the smallest, and often in the male obsolete or 

 only represented by a point. 



This fonn was also taken in the lower parts of the Rilo 

 Mountains up to 4000 or 5000 feet, though not so large 

 and well-marked as at Slivno. 



It is usually known in collections as medusa, var. 'psodea, 

 Hub., or eumenis, Frr., and is considered by Staudinger 

 as a form of medusa. It is the typical form in the Balkans 

 in Podolia and Hungary, and occurs in the Aljjs and 

 Germany as an aberration. 



At a higher elevation in Kilo Dagh, up to say 7500 

 feet, a smaller form of medusa or oime, some of which might 

 be called hipjpomcdusa, Ochs, was common in company 

 with a species of similar size, most like one which is 

 common in the Alps of Styria in Bosnia and possibly 

 elsewhere, and is known in collections as ceme, var. spodia, 

 Stgr, When taking this we could usually distinguish 

 the males by tlie colour of the fore-wing below, which is 

 tinged with the chocolate colour of the band, the lower 

 part of which is indefinite and fades into the ground colour 

 of the wing, whereas in medusa it is much more sharply 

 defined. 



The females are more easy to distinguish, as they have 

 the same difference, and also as a I'ule have the ground 

 colour of the winces more fulvous. There are some
