DPiAGONFLY SEASON OF 190^. 

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



Little of fresh interest has to be recorded in connection 

 with the dragonfly season of 1901. No new species was dis- 

 covered, and all the critical species, which were known to be 

 really British, but about whose status there was uncertainty, 

 had before this season been re-established. 



On April 24th, in the New Forest, I met with the first speci- 

 men, an Agrionid, which flew by out of reach ; the next day I 

 took three Pijrrhosoma nymphula. This early promise, however, 

 was not kept up. The next species seen was Enallagma cyathi- 

 gerum, in small numbers at the Black Pond on Esher Common, 

 and at the same time and place, one of a larger species, probably 

 Libellula quadrimaculata, was sighted. On May 29th a male 

 Agrio7i paella was taken near Ashtead. By June 4th this species 

 was plentiful on Bookham Common, where also a larger dragon- 

 fly, probably Libellula depressa, was seen. The next day, June 

 5th, L. qiuidrimacidata, A.puella, E. cyatJiigeriim, and P. nymphida 

 were out at the Black Pond, and Pyrrhosoma tenellum was appa- 

 rently just appe£\,ring. Till near the beginning of June, there- 

 fore, it could scarcely be said that the dragonfly season had 

 commenced in earnest. 



At the Black Pond, on June 5th, I found a nymph of L. 

 quadri mac (data, from which the imago had just commenced to 

 emerge. It happened to be near the bank, and, though it was 

 tedious and tiring to stoop and watch the process, I stayed till 

 emergence was complete. The nymph was discovered about 

 11 a.m., and by 11.40 the imago had completely emerged. Out 

 of this time the " rest," with head hanging vertically down- 

 wards, lasted nearly or quite half an hour. The " spring-back " 

 was quite sudden, the abdomen being pulled out of the nymph- 

 skin almost immediately afterwards. While hanging at " rest " 

 the lower lip seemed to expand. When an emerging dragonfly 

 hangs head downwards, does it do so to allow of the filling out 

 and expanding of the fore parts ? 



On June 19th a visit was paid to Frensbam Ponds, in Surrey, 

 to test its dragonfly fauna, but unfortunately the day was gener- 

 ally dull and unsuitable. Numbers of E. cyathigerum were
