$2 THE ENTOMOLOGIST ’S RECORD. 
cerisyt @ (lower down). Next day I tried the low vineyards south- 
west of the town, hoping to catch a good series of M. larissa, but the 
day was unfavourable and I met with no success. I took a beautiful 
Chariclea treitschkit, sitting on a stalk of grass. This beautiful insect is 
not uncommon at Slivno. Haberhauer rearsa great many for sale, as 
well as C. delphinii and C. victorina, and it was a daily pleasure to see them 
stretching their lovely wings as they emerged from the moss in his pupa- 
case. June 8rd we tried the lower slopes of Tschatalka again, in hopes 
of getting more specimens of P. chlorodyce, but I only caught two, and 
saw two others which I failed to secure. Itisa fast butterfly, and flies 
very like P. callidice, a delightful insect to catch—if you can. It is 
generally common in these little glens. Haberhauer tells me that he 
has sometimes taken as many as 100 specimens during the first week 
of June, but 1899 was a bad year for the locality, on account of the 
devastation caused by a waterspout in June, 1898, which tore up much 
of the hillside and destroyed the larve. We also entirely failed to 
find S. cinarae, which is generally to be had in the same locality, but 
never in any abundance. Haberhauer generally gets five or six speci- 
mens in the course of the season. June 4th was my last day at Slivno. 
I now rather regret that I did not stay a few days longer, as I think I 
might have secured a better series of P. chlorodyce, M. larissa, and L. 
semiargus var. parnassus. But I fully expected to find all these insects 
again in the Rilo Dagh and Rhodope, being quite unaware of the cold 
and rainy climate that prevails in these high frontier mountains of 
Bulgaria, where the weather rather resembles that of the Bavarian 
Alps than what one might expect to find in lat. 42°. I went to the 
vineyards south-west of the town, and took seven good specimens of 
M. larissa (all darker than those I got in Hercegovina), besides a few 
T. cerisyt 9 anda Sesia or two. A long and wearisome railway 
journey brought me back to Sofia on June 5th, and the next day was 
fully occupied with arrangements. for an excursion to the great 
monastery of the Rilo, one of the oldest and richest foundations of 
Bulgaria, situated about forty miles due south of Sofia, close on the 
Turkish frontier. It takes a good two days’ journey to get there from 
Sofia whichever road you may take, as you have to get round or over 
the steepest and wildest mass of mountain in the whole country. We 
took a carriage and drove there in two days by Dubnica and the valley 
of the Struma, the road often very bad, and the hill country not par- 
ticularly interesting as far as Dubnica, where we slept at a tolerable 
‘hau,’ or inn. I saw no insects of any interest, except one fine specimen 
of C. dispar var. rutilus, which I caught in the Struma Valley. I saw 
several more of these, but did not stop to catch them. The drive from 
Dubnica down the Struma to the town of Rilo was again dull, but 
after turning up the valley of the Rilska (a tributary of the Struma) 
we came into fine scenery, and saw a good many insects, 7. cerisyi 
among them. Haberhauer had formerly taken it in quantity around 
Dubnica, which he considers to be its probable western limit. On the 
road I took L. amanda and one L. semiargus var. parnassus, but not as 
well marked as those I got at Slivno. We followed the valley of the 
Rilska about ten miles up from its junction with the Struma before we 
reached the monastery, which stands about 4000 feet above the sea in 
a very steep and narrow valley, cut like a trench, through a mass of 
granite ridges, which rise in precipices to a height of 8000 feet close
