THE DRAGONFLY SEASON OF 1895. 99 



a later, smaller, and less common insect, was just coming on the 

 wing at the Pond on June 9th. It was soon out in swarms, and 

 was secured as late as Sept. 10th, three months after its first 

 appearance. 



Enallagma cyathigerum was first noticed on May 8th at the 

 Black Pond, and was still on the wing at the same place on 

 Sept. 29th, nearly five months later. How many broods the 

 specimens belonged to, I cannot say. On more than one 

 occasion I came across this dragonfly caught by the round- 

 leaved sundew {Drosera rotundifolia) . When found the insects 

 were quite alive, although the tentacles on the leaves had closed 

 over and secured the prisoners by the abdomen. With this 

 insect no specimen of Agrion puella was taken, though a few 

 were captured at a tiny pond in the same locality. At Wisley 

 Hut Pond, on the other hand, A. puella was present in plenty on 

 July 29th, while but one E. cyathigerum was taken. 



At the Black Pond, on June 4th, a specimen of Ischnura 

 elegans was secured, this being a new record for the locality, 

 where, however, I cannot say definitely that I saw another speci- 

 men. The species was out in swarms at Wisley Pond on July 

 29th; and I am also able to record it for Surrey, at Merton, 

 July 7th ; on Wimbledon Common, June 30th ; and on Chobham 

 Common, June 16th. 



One single specimen of Platychnemis pennipes, a well-marked 

 female, turned up at the Black Pond on June 9th, furnishing yet 

 another new record for this prolific locality ; but this local insect 

 was secured in larger numbers near Kipley on the 23rd, by which 

 date it was going over. 



Lestes sponsa I have only taken at Wisley Pond, where, how- 

 ever, on July 29th, with Ischnura elegans, it was on the wing in 

 swarms. 



Calopteryx splendens is the only other Agrionine dragonfly 

 whose acquaintance I made during the season. It was out in 

 abundance on June 3rd, between Byfleet and Wisley, and on 

 June 23rd, near Kipley. The males varied greatly in the depth 

 of the blue colouring on the wings. 



Of the Libelluline dragonflies, the first to appear was Libellula 

 quadrhnaculata, on May 8th, at the Black Pond. The specimens 

 on that day were mostly pale and limp, and had apparently but 

 just emerged. They were on the wing till July 6th, after which 

 I was able to record no more. But on Sept. 9th I was surprised 

 to see a specimen, which, however, spite of long and patient 

 waiting, was not secured. As I think it was impossible to 

 mistake the species, I am driven to conclude that it was an 

 autumnal appearance due to the lengthened summer weather. 

 The species was also observed near Byfleet and at Wisley Pond 

 on June 3rd, and at Chobham Common on June 16th. 



A limp specimen of Cordulia cenea was just out at the Black
