ON SOME FURTHER DRAGONFLIES FROM MACEDONIA. 203 



numbers, but no captures were then made. After nightfall, 

 however, it was quite easy — with the moonlit sky serving as a 

 background— to detect individuals of both species resting upon 

 the thorn-bushes {Paliurus spina-christi, Mill.) which occur in 

 patches upon the higher slopes of the hill. All the specimens 

 recorded below from Janes Hill were taken in this way with the 

 bare hand. Both ^E. mixta and S. striolatum were observed to 

 r-emain on the wdng throughout November, although no speci- 

 mens of either were seen after about the first week in December. 



In England Calopteryx virgo seems to prefer streams with a 

 gravelly bed, while C. splendens commonly frequents water flowing 

 through a muddy channel. Capt. Waterston was invited to take 

 note of the conditions prevailing in Macedonia, and he reported 

 that at Stavros C. virgo haunts a gorge traversed by a clear, 

 rapidly-moving stream, with no mud and few bordering aquatic 

 plants of any kind. The stream is overhung by trees, largely 

 Oriental planes, on the leaves of which virgo often rests. C. splen- 

 dens occurred (a) along the banks of a muddy ditch with hardly any 

 current, near Salonica ; {b) by the side of a rather muddy lagoon 

 at Stavros ; (c) at the west end of Lake Beshik, the bottom of 

 which is certainly muddy; and (d) at the stream side on lower 

 reaches of the Rendino River, where the channel is gravelly and 

 muddy by turns. 



With the exception of Agrion puella, Linn., and Sympetruni 

 fonscolombe't, Selys, all the species taken before were met with 

 again last summer,- including Selysiotheniis nigra, Lind. The most 

 interesting additions were Kpallage fatime, Gharp., Lestes macro- 

 stigma, Eversm., Cercion lindenii, Selys, Agrion scitulam, Ramb., 

 Vanderia tetraphylla, Lind., and Gomphus favipes, Charp. 



Mr. K. J. Morton has been good enough to examine certain 

 material which presented special difficulty in determination, and 

 many thanks are tendered to him for much kind assistance in 

 this direction. 



The collection is being presented to the British Museum 

 (Natural History), which has always been singularly poor in the 

 matter of Mediterranean Odonata.
