Butterfiics of Bulgaria. 205 



110. C. tipJion, var. rhodopcnsis, n. var. 



This butterfly was very cotntnoQ in Rilo Dagh from 

 about 4000 to at least 7000 feet, and was not confined to 

 particular habitats, though commonest on wet mountain 

 meadows. It was out in the middle of June, and fresh 

 specimens could be got a month later. On comparing 

 them with my numerous specimens of tiphon from all parts 

 of Europe and Asia I find that they differ from normal 

 European specimens in having in most cases the apical 

 band of fore-wing below obsolete, but some specimens 

 (about one thinl) show a trace of this band, and some of 

 these cannot be distinguished from two specimens of tiphon 

 from Stettin, and are also very close to, but much larger 

 and darker than, what I took in the Altai Mountains 

 (c/. Trans. Ent. Soc, 1899, p. 363). 



On sending a specimen of the Rilo form to Dr. 

 Staudinger he writes as follows — " Here you have found 

 something really interesting. This specimen agrees with 

 four or five males that I received many years ago from 

 Haberhauer from the Caucasus without exact habitat. 

 I have described it as symphita, Led., var, tiphonides, 

 and from these specimens consider sympJiita (which I 

 received in quantity from Achalzich in Armenia) also as 

 a probable form of tiphon." As to the identity of tiplion 

 and sympliita my specimens of the latter are not sufficient 

 to enable me to judge, but certainly the Bulgarian form is, 

 on account of the grey patch on hind- wing below, much 

 nearer to tiplwn than to symphita, which (in the specimens 

 I have) wants this jjatch entirely.
