DRAGONFLY SEASON OF 1904. 179 



found, one Ischnura elegans, and one teneral male Orthetrum 

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

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

 little 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 eenea were seen ; this was the only 

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

 E slier Common, I caught a male of L. depressa, a species of 

 which I met with very few during 1901. On the same day 

 Pyrrhosoma tenellum was very numerous at the Black Pond. 

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

 L. quadrimaculata. 



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

 of Mschna isosceles, and the other good dragonflies to be 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 

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

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

 there were absent or unnoticed. There were present Mschna 

 grandis, Calopteryx splendens, Platycnemis pennipes, Erythromma 

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

 and Enallagma cyathigerum. 



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

 A worn female Orthetrum cancellation was taken on August 1st, 

 and a female Mschna juncea on August 9th. A Calopteryx virgo 

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

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

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



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

 Lestes sponsa, a few iEschnas, 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 juncea 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.
