126 THE ENTOMOLOGIST. 



Anax imperator, Leach. Several were noticed on 14 June at 

 the Black Pond, Esher Common, Surrey, although dragonflies 

 did not seem to be very numerous in the neighbourhood. 



Libellulidse. 



Cordulia aenea, Linn. One male was taken at Marlborough' 

 Deeps in the New Forest on 6 June, perhaps the only specimen 

 seen. This capture is an interesting one, since the species is 

 but little known and apparently quite uncommon in the Forest. 



Libellula quadrimacidata, Linn., was fairly common on the? 

 same date and at the same place as the last. 



Orthetrum caeridescens, Fabr. On 3 June there appeared to» 

 have recently been a great " hatch " of this species, for they 

 were plentiful on that date in the Forest, though still teneral ;. 

 but by 9 June some were acquiring a blue tint. This species 

 seems to take some time to develop the cerulean bloom. 



Sympetrum striolatum, Charp., appeared to be less common, 

 than usual, possibly in consequence of the drought. On 9 Oct.,. 

 a warm day, considerable numbers of Sympetra, no doubt all 

 S. striolatum, were flying, some connected per collum and the? 

 female ovipositing, at the large pond on Epsom Common,. 

 Surrey. All the examples captured were of this species. 



Synipetrum sanguineum, Mull. A female was taken at the 

 Hut Ponds near Wisley, Surrey on 22nd August, and possibly 

 the species was seen there as late as 25 Oct. 



Sympetrum scoticum, Don., was noticed at the ponds just, 

 mentioned on 22 August. 



Calopterygidse. 



Calopteryx virgo, Linn. After being first met with in the- 

 New Forest on 19 May, it was found to be common on the 22nd,. 

 though few comparatively had attained a blue tint to the wings ;. 

 the same thing was noticed the next day. By 8 June, however, 

 the wings were commonly blue and the insects made a fine show- 

 as they flitted about in the sunshine. On 22 July they were.- 

 passing, only occasional specimens being seen. They dis- 

 appeared earlier than usual, as was perhaps to be expected. 



Lestidse. 

 Lestes sponsa, Hans. This dragonfly was noticed but once — 

 at the Hut Ponds on 22 August. It is really one of our common, 

 dragonflies, but the naiad seems to be rather elusive, and the- 

 writer would be glad to receive some, or their empty skins. 



Agrionidse. 



Platycnemis pennipes, Pall., was first seen on 4 June, in the- 

 New Forest, and the specimen happened to be the var. lactea,. 

 Charp. 



Ischnura elegans, Vanderl., was not sought for. After findino-
