DRAGONFLY SEASON OF 1904. 179 



found, one Ischnura elegans, and one teneral male OrtJietium 

 cancellatum. The day was not wasted, however, for a few 

 nymph-skins of the last were discovered, and, as these were 

 Uttle known previously — scarcely at all in Britain — they were at 

 least of equal value with the rather scarce imagines of the same 

 species. 



At or near the Black Pond, on June 22nd, one or two Anax 

 imperator and one Cordulia cenea were seen ; this was the only 

 C. cenea that I noted during the season. On June 26th, on 

 Esher Common, I caught a male of L. deprcssa, a species of 

 which I met with very few during 1904. On the same day 

 Pyrrhosoma tenellum was very numerous at the Black Pond. 

 There also, on July 16th, I took a very nice var. prcenubila of 

 L. quadrimac'idata. 



Mr. G. T. Porritt again visited the Norfolk Broads in search 

 of .Eschna isosceles, and the other good dragonflies to he found 

 there in early summer. He met with fair success as regards 

 isosceles, and, writing on June 25th, said that he had taken one 

 hawking on land, as M. cyanea does, when it was nearly dark. 



On July 23rd a visit was paid to the Basingstoke Canal, near 

 Bydeet Station, when the species found were the usual ones for 

 that part of the season, though some that should have heen 

 there were absent or unnoticed. There were present /Esclma 

 grandis, Calopteryx splendeus, Platycnemis pennipes, Erythromma 

 naias, Ischnura elegans and its var. rufescens, Agrion pidchellum, 

 and Enallagma cyathigerum. 



Some weeks spent in the New Forest revealed little new there. 

 A worn female Orthetnim cancellatum was taken on August 1st, 

 and a female Msckna jiincea on August 9th. A Calopteryx virgo 

 was seen as late as September 3rd. On September 2nd Cordide- 

 gaster annulatiis was seen on the wing at Becton Bunny, on the 

 coast, and a female .Esclma cyanea was caught at Milton. 



Wisley Ponds, in Surrey, were visited on September 10th. 

 Lestes sponsa, a few ^schnas, and Sympetrum striolatum were 

 found at the smaller pond, but none of the better species of 

 Sympetrum were met with. There was, however, very little sun. 



On September 18th an Mschna juucea was taken at the Black 

 Pond, where for one or two seasons this species had been seen by 

 me very seldom, if at all. 



Mr. F. B. Browne was good enough to give me a female 

 specimen of Agrion armatum from the Broads. Of the species 

 he took about ten specimens in the spring, one only being 

 a male. 



My last record for the season was Sympetrum scoticum and 

 S. striolatum, at the Black Pond, on October 9th. The latter, 

 however, probably continued well into November, and not im- 

 probably the former may have lasted almost as long.
