But ferries of Bulgaria. 195 



The commonest and indeed the only Lycxna at high 

 elevations in Rilo Dagh, where it was very common at 5000 

 — 7000 feet and perhaps higher. Most, but not all, of the 

 specimens show on the hind-wing below the reddish 

 marginal spots which are characteristic of the var. imr- 

 nassia, Stgr., from Greece ; but that is normally a small 

 form, and all my specimens are large. The var. helcna is 

 an extreme development of the same. 



47. L. a Icon, S. V. 



Not uncommon at about 3500 feet near Rilo Monastir. 



48. L. iolas, Ochs. 



Common at Slivno, but not seen in Rilo Dagh. 



49. L. ario)i, L- 



Also common at 3000—4000 feet. 



50. Ncmcohlas luciiia, L, 



A few, mostly worn, of the first brood were taken late in 

 June at Rilo; others were flying in bushy ground on July 

 25th in the plains north of the Balkans. These must 

 belong to a second brood, but the species in most places 

 seems to be only single-brooded. 



51. Apatura iris, L. 



Common near Kostenetz, the males fresh out on July 14th. 



52. A. ilia, var. cl title, Schiff. 



We did not take this in the Rilo Dagh, but it occurs at 

 the foot of the hills, and was very numerous on the willows 

 by the side of the road near Sofia on July 21st. Most of 

 the specimens were by that time much worn. 



53. Limcnitis ijopidi, L. 



Occurred near llilu Monastir at about 3000 feet, but 

 not abundantly. 



54. L. camillii, Schitf. 



Only once taken at Kostenetz. 



55. L. sihylla, L. 



Commoner than the last at Kostenetz.
