DRAGONFLIES IN 1901. 

 By W. J. Lucas, B.A., F.E.S. 



Though there is no record of the capture of a new species to 

 be made for the year 1901, yet in some respects the season was 

 an interesting one. The earUest imago noted was a male 

 of Pyrrhosoma nymphula — at the Black Pond, in Surrey, on 

 April 28th. By May 12th, three or four species were on the wing 

 at the same place, though even on May 19th such early species as 

 Galopteryx splendens and P. nymphula were still in the teneral 

 condition at Send, also in Surrey. But during the summer 

 weather at Whitsuntide, which fell at the end of May, dragon- 

 flies were numerous, some ten species being noticed on the wing 

 in the New Forest during the week-end. 



Sympetrum striolatiim was, of course, noticed at several new 

 localities, amongst them being Cumbrae, in Buteshire (A. M. 

 Stewart) ; Frensham Great Pond, in Surrey (E. B. Bishop and 

 W. J. Ashdown) ; Pokesdown and Stour side, in^ Hants ; and 

 Totness, in Devon. The species was very plentiful on Esher 

 Common in the autumn, as was also S. scoticum. The latter was 

 found at Pokesdown, in Hampshire, and a large number, all 

 practically normal in size and colouring, were received from 

 Kogart and Lairg, in Sutherlandshire (J. M. Munroe). 



Libellula depressa was common and mature in the New Forest 

 between May 25th and 28th. It was found in several districts in 

 Yorkshire (G. T. Porritt) ; and near Bedford (R. W. Thompson). 

 L. quadrimaculata was first seen at the Black Pond on May 12th ; 

 on June 9th it was in considerable numbers there, and a var. 

 prceniihila was taken ; it was still about on July 8th. It was found 

 at Frensham Great Pond, Surrey (E. B. Bishop) ; Mr. C. A. Briggs 

 received some specimens from Mr. McArthur, taken at Stornoway, 

 in Lewis ; and Mr. A. M. Stewart sent me one taken by Mr. Duns- 

 more in July in the island of Arran (Scotland). British odonatists
