Melitaea didi/tna.—hoca], but abundant where it occurs, from the middle 

 of May to June. 



M. trivia. — One specimen only, ilying with didyma. 



M.phoebe. — Abundant in ravines from the end of Ajril to June. 



Polygonia C'-album. — One specimen only ; March. 



Vanessa polycJihros. — One only; April. 



V. 10. — Only seen twice ; March and June. 



Pyrameis atalcmta. — In a ruined village where I was on duty for several 

 montlis this butterfly was very common, sailing to and fro in tlie gardens in 

 the fearless friendly way one associates with the insect. It was on the wing 

 till December, when it went into hybernation, although the weather was still 

 mild and open. It appeared again in March. 



P. canlui. — The most abundant of all Macedonian butterflies. In the 

 autumn of 1918 I found hundreds round a barley stack. I'resuniabiy tliey 

 had gone there to roost, but the numbers upon and flying round the stack 

 were uncountable. 



Satyrus meyaera. — Moderately common from April to October. All the 

 specimens I examined were of the var. lyssa with grey hindwiugs. Another 

 noticeable difference is that the subsidiary eye near the tip, which is only a 

 small spot in the type, is clearly ])upilled in the var., and the eyes on the 

 hindwings beneath are larger and more distinct. 



Coenonympha paviphilus. — Abundant from April to November. All of the 

 var. Jylliis, which are larger, the apical spot is more distinct and there is a 

 submarginal row of small spots on the hindwings. 



Hipparchia briseis. — Not very common, but seen occasionally in .June and 

 again in autumn. I found it only in the roughest and stoniest hollows, and it 

 was hard to capture, being strong on the wing. 



JSpiitephele lycaon. — I may have overlooked this, the male being very like 

 jurtina, but I have only one specimen, a female taken near Lake Uoiran in 

 September. 



E.jurtina. — Abundant from May to September. In one ravine I found 

 a number of curious forms, darker than noi-iual, but with much albinism, 

 especially round the outer margins of the hindwings. There was also a good 

 deal of distortion, the affected wings being often crumpled and shortened. 



31elanaygia larissa.—ThQ only "Marbled White" taken. A few only 

 seen flying over reeds near the Spanc River in May. Much stronger on the 

 wing than the British species. 



Thecla acaviae.—A few fresh specimens found flying round a vetch 

 in May. 



2\ rubi. — One specimen only ; April. 



Lycaena thersumon.—Ex.treme]y abundant on Janes Plain, but elsewhere 

 I only met two isolated specimens— one near Kasimli in July, the other on the 

 banks of the Ardjau in August. At Janes it was abundant during August and 

 September, and in 191H the first brood appeared in the tirst week of May,
