156 THE ENTOMOLOGIST. 



we saw several specimens of Apatura iris and A. ilia var. 

 clyte, but did not succeed in securing either of them. The 

 most abundant butterfly was a Melitaa, which turned out to 

 be M. athalia var. mehadensis, and this insect settled in little 

 companies on damp places in the road and on the horse-drop- 

 pings. Wherever we went in the northern districts of Bosnia 

 we met with it in great numbers. Just as we were leaving 

 Jesero, near a picturesque mill, Mr. Barraud caught a fine 

 specimen of Eugonia xanthomelas, the only one seen in the 

 course of our wanderings. We walked a mile or so along 

 the road beyond Jesero, and then turned up a valley on the 

 right, where I saw Parnassius apollo. We had ordered lunch 

 to be prepared for us at the little restaurant by the lake, 

 and on our way back, in a flowery corner on the edge of a 

 small field, we observed some Theclids flying over the brambles, 

 and eight specimens of T. spini and one of T. acacia fell to my 

 lot. After we had done justice to the trout we started to walk 

 back to Jajce, intending to work the boggy ground by the lake- 

 side, but the excessive rainfall had caused a rise in the water 

 level, and it was quite impossible to wander many feet from the 

 roadway. At one spot, however, where the ground was a little 

 higher and dryer, we were able to investigate a small meadow 

 in which the grass was uncut, and here I took several tiny 

 Melitseas, only '28 mm. in expanse, which puzzled me. They 

 proved to be dwarf specimens of M. aurelia, a species of which 

 I took a short series of varying sizes on the margins of these 

 low-lying meadows. A. phoebe, too, was flying in nice condition, 

 and several specimens of A. thetis were added to the bag. The 

 following day we determined to see what was to be had on higher 

 ground, so we engaged a guide, hoping to find some mountain 

 butterflies. But the quest proved rather disappointing, the 

 hillsides being either closely grazed or so steep and stony as 

 to prove very poor collecting ground. The most noteworthy 

 capture was the striking aberration navarina of M. athalia, 

 which I found in a meadow by the side of the railway on 

 our homeward journey. Over the skrees S. hermione was flying, 

 and at a turn of the footpath Lycana areas found its way into 

 the killing-bottle. After dinner that evening we strolled about 

 the village, boxing a few moths from the white walls of the 

 houses, below the arc lamps, which attracted night-flying insects 

 in swarms, but which were too high up to be of much use for 

 collecting purposes. Chcerocampa porcellus and Cossus ligniperda 

 were the most conspicuous insects taken. 



From Jajce we went to Banjaluka through the beautiful and 

 verdant gorge of the Urbas, and on the fifty miles drive I think 

 I saw more butterflies than during the whole of the rest of the 

 holiday put together, the Melitaeas swarming on the road in 

 countless thousands. It was glorious butterfly weather, but
