0. brunneum, Fonsc. — 1 S > adult, Yeuidje Vardar, 5, v ; 1 $ , 

 Vaidar Plain, 14, v; 1 ?, Stavros, 26, v; 3 c?, L- Beshik, 

 1-3, vi ; 1 S , Stavros, 7-8, vi ; 2 cf , 2 ? , L. Adji Geul, 18-19, 

 vi ; 4 (^ , 4 $ , L. Adji Geul, 4, viii. The female from Vardar 

 Plain has the triangle in each hind wing three-celled, although 

 the subdivision is not quite complete on the left side. 



0. cancellatum, Linn. — 2 (^,2 2, juv., Yenidje Vardar, 

 5, V ; 3 c? , 3 ? , Stavros, 23, v ; 3 2 , L. Beshik, 1-3, vi ; 1 (? , 

 Stavros, 7-8, vi, 



Libellula quadrimaculata, Linn. — 3 (^,4 ? , L. Beshik, 1-3, 

 vi. Three of the specimens (2 3,1 ? ) make an approach 

 towards var. prcsnubila, Newm., inasmuch as their wings are 

 marked with a more or less well developed subapical brown 

 cloud. 



L.ftdva, Miill. — 7 ^ , 4 $ , L. Beshik, 1-3, vi ; 1 <? , Stavros, 

 7-8, vi ; 1 3 , Eendino Gorge, 8, vi. The males from Lake 

 Beshik are in different stages of development and vary somewhat 

 in size, the length of the abdomen ranging between 24*5 and 

 28 mm. The subcostal space in the fore wings is free from any 

 black streak, and very few of the wings have any apical cloud or 

 spot. The four females, which still retain much fulvous colora- 

 tion in the venation, have all the wings quite heavily tipped with 

 brown. In four of the males from Lake Beshik and in both of 

 those of later date the pruinosity has been rubbed away, by the 

 legs of the female during copulation, from the sides of segment 

 5 of the abdomen. 



L. depressa, Linn. — 1 ? , Vardar Plain, 14, v. 



Crocothemis erythnea, Brulie — 3 <? , 6 $ , Yenidje Vardar,

S. sanguineum, Miill. — 1 5 , L. Adji Geul, 4, viii. 



Selijsiothemis nigra, Lind. — 4 $ , L. Adji Geul, 18-19, vi ; 

 1 (? , L. Adji Geul, 4, viii. Abundant at* this locality in June, 

 several examples seen in or near its old haunts at Milov9i, and 

 plentiful round the sides of Lake Ardzan, near Dragomir, during 

 the last three weeks in August. Its white-veined wings make it 

 easily recognisable in flight, " as does another peculiarity, viz. 

 its preference for hawking low down over rough herbage at some 

 distance from water." Capt. Waterston adds, " I have only once 

 this year seen it actually flying over a water surface."
