BRITISH ODONATA IN 1912. 181 



la the Broads, too, dragonflies were found to be rather early 

 by Mr. G. T. Porritt. Writing June 11th, he says:—*'! spent 

 Whit Week at the Norfolk Broads, but found Agrion armatum very 

 scarce. Indeed I took only four (three males and one female) 

 all the week, and saw perhaps six or eight more. I rather 

 think I was too late for it this early season, as it was probably 

 well out during the hot weather we had at the end of April. 

 Even .1. pulchellum, usually the commonest dragonfly of the 

 Broads, seemed in much reduced numbers and going over. 

 Libellula falva was common, but the specimens I netted— of 

 both sexes— were immature, as probably most, if not all, were. 

 I certainly did not see a single adult blue male ; but one cannot 

 well work for L. falva and A. armatum at the same time. The 

 commonest dragonfly in the Broads was Erythromma naias, 

 which abounded and was on the wing all day up to 7 o'clock in 

 the evening, when there was any sun." 



Mr. Corbett, on Whit-Monday, visited Askern in Yorkshire, 

 one of the older localities for L. falva, and found the species 

 common, but all the specimens teneral. 



Mr. 0. Whittaker found Ischnara elegans abundant during 

 May on the canal between Droitwich and Salwarpe, in 

 Worcestershire — the only dragonfly in evidence there. He also 

 found in May Calopteryx splendens on the Severn at Holt Fleet, 

 in Worcester. At Studland, Dorset, Col. Yerbury took I. elegans, 

 female, var. rafescens on May 8th and Enallagma cyathigerum, 

 males, on the 11th and 12th. 



Mr. S. A. Blenkarn met with the following species in the 

 Isle of Wight, the dates given being those on which the various 

 species were first seen : — " Libellula depressa, one male, at a 

 pond on Sandown cliffs. May 26th ; and at Brading Marshes on 

 the 28th. Brachytron pratense, common at Sandown Marshes, 

 May 18th. Calopteryx virgo, one, Brading Marshes, May 28th 

 (new to the Isle of Wight list). C. splendens, one male, Sandown 

 Marshes, May 24th; two males, Brading Marshes, May 28th. 

 I. elegans, common, Sandown Marshes, May 18th. P. nymphida, 

 a few, Sandown Marshes, May 25th. Pyrrhosoma tenellum, 

 a few, Sandown Marshes, May 28th. A. pulchellum, a few, 

 Sandown Marshes, May 25th. E. cyathigerum, common, San- 

 down Marshes, May 18th." I took P. tenellum myself on June 

 9th at the Black Pond. 



Writing from Bournemouth, Mr. E. J. B. Sopp said :— " I 

 found C. splendens common at Throop in June, but I. elegans 

 was not nearly so common in the district as in 1911. At 

 Littledown, in June, Anax imperator and E. cyathigerum were 

 common after the middle of the month (I did not go there 

 before). Mr. Kenneth Ryde told me of a big dragonfly that was 

 common along the river Bourne (towards Westbourne) near 

 the end of July. I asked him to catch one, and it turned out to
