﻿136 THE ENTOMOLOGIST. 



as August 18th S. scotkuin and S. striolatum * were seen in 

 teneral condition, and the former was still emerging, if not the 

 latter also. I brought away a nymph-skin of ^. scoticum, and 

 from that and others I have made the drawing and description 

 of the nymph which accompany this paper. On August 19th 

 in Pound Hill Inclosure I captured a nice female, M. cyanea, 

 with greenish markings. When I removed it from the net it was 

 headless. The head was, however, found clinging to the inside 

 of the net. Apparently it was biting the net, and either could 

 not or would not let go, and its body was dragged from its head. 

 How slight is the connection, and how small must be the separate 

 particles of food that can pass into the stomach ! I was surprised 

 at capturing a female L. depressa at Oberwater so late as August 

 29th. The specimen was in such good condition that it could 

 not have been on the wing, one would think, since the beginning 

 of the season. A male and a female of C. virgo were seen on 

 August 31st, after I had lost sight of the species for several days. 

 On September 2nd P. tenellum and S. scoticum were numerous, 

 and I took a male A. mercuriale ; 0. carulescens was in consider- 

 able numbers. On September 5th *S'. striolatum was very common 

 in the bright sunshine during the afternoon in a ride near 

 Woodfidley. During my stay in the Forest C. annulatus was 

 again common. On September 7th near Holmsley M. cyanea 

 and M.juncea were found to be rather common, and I captured 

 of the former three males, and of the latter one male and two 

 females. A male pounced down on a female, which I had not 

 noticed on the surface of the vegetation in very shallow water. 



1 succeeded in capturing both, and found them to be : one a male 

 JE. cyanea and the other a female M.juncea, and they evidently 

 were intending to pair. Later, a male was seen to fly down to 

 a female in a similar way ; but this time I caught the female 

 only — ^.juncea. After this, two or three males kept flying to 

 and from the spot, and their manner left no doubt that they were 

 searching for the female. At last I captured one and found it to 

 be M. juncea. 



More than once I visited the pond where, in 1911, Sympetrum 

 fonscolomhii, Selys, occurred, and I think it may safely be said 

 that none were present in 1914. Mr. Haines, however, was 



* In continuation of the interesting notes supplied by Miss D. Molesworth 

 {vide Entom. xlvii. p. 80), she adds, writing March 10th, 1914 : — " Of the 

 Sympetrtim eggs, which I told you of as having hatched in less than three 

 weeks last autumn, the largest, in a big aquarium, is now about 9 or 10 mm. 

 long, while none of those of the same batch, in a small bottle, have reached 



2 mm. in length. I feel almost certain that the smaller nymphs did not 

 hatch till quite two months after the larger ones, for the latter ate all their 

 relatives that I could see, and were nearly 3 mm. in length before I removed 

 them to a bigger aquarium. I notice that a demoiselle nymph, which had 

 lost two of its ' tails,' has now got two half-sized new ones by its last 

 change of fekin."
