66 THE KNTOMOLOGIST. 



was taken in 1898, but was put away unset, not being dis- 

 tinguished at the time from S. striolatum, which it so closely 

 resembles. Males of Sijmpetriimjlaveolum were again present on 

 Ockham Common, and Major Robertson secured a male at Denny 

 Bog, in the New Forest. No females were again detected. 

 Should we still consider their presence due to an immigration ? 

 Dr. F. A. Walker took both sexes in Alderney in June and July. 

 Males and females of Sijmpetrum sanguineum were taken on 

 Ockham Common. Could it have been overlooked when for 

 several seasons, a few years since, Mr. C. A. Briggs worked the 

 locality so carefully? The species was received from Hors- 

 monden, in Kent (R. South), 



About Libellula quadrimaculata the most interesting point is 

 a large migration noticed in the west of Europe in June. By 

 some continental observers it was thought to have come from 

 England. The reverse, however, was the case. At Margate, on 

 June loth, Mr. H. Stocks observed an immigration of what by 

 description must have been dragonflies of this species. The same 

 flight was also observed by Mr. A. J. Mann between Margate and 

 Broadstairs the same day : Mr. Mann took three specimens. On 

 June 19th Mr. G. Bolam, of Berwick, wrote to the Editor of the 

 ' Entomologist,' saying that he had seen an immigration, pre- 

 sumably on July 17th : that it was of L. quadrimaculata was 

 proved by the specimen forwarded for identification. Part of the 

 migration appears to have reached Huddersfield {vide Entom. 

 xxxiii. pp. 210, 247, 248). Libellula fidva does not seem to have 

 been noticed during the season. 



Orthetrum candescent was again very common in the New 

 Forest. It was just coming on the wing during the first days of 

 June, when one was taken (F. M. B. Carr) with lateral dark 

 bands on the abdomen, somewhat like those in its British con- 

 gener. A nymph-skin was obtained on June 5th in the company 

 of a newly-emerged imago, and another as late as the end of 

 July. They somewhat resemble Sympetrum scoticum in general 

 appearance, but are darker and slightly incrusted with mud. 

 Apparently they are bred in the very wet boggy ground rather 

 than in the pools or streams. A new Surrey locality is Chob- 

 ham Common (E. Vincent). A female of Orthetrum cancellatmn 

 was taken by Mr. D. Kirkaldy at the Broads — an interesting 

 capture, as there have been no records of late years except from 

 the South of England. 



A specimen of Gomphus vulgatissimus was taken at Walton- 

 on-Thames (A. B. Higgs), and Mr. McLachlan tells me he took 

 several at Weybridge in 1871 ; many nymph-skins were also 

 taken at Eynsham, in Berkshire (A. East). These points 

 strengthen the position of G. vulgatissimus as a Thames insect. 

 Two captures in the middle of last century (i9th) have been 

 made known for Sussex.
