bution, which is certainly very wide. But I regret not having placed 

 examples of both sexes in alcohol, because I have reason to think 

 that my figures ("Rev. and Synopsis") are susceptible of improve- 

 ment, and it is very difficult to define the complicated anal parts in 

 dry individuals. Furthermore, a fresh study of T. interna, McLach., 

 from Turkestan, is probably necessary. Of this latter I have 2 <$ 

 and 3 ? . In one <$ the anal parts agree fairly well with my figure 

 ("Rev. and Synopsis") ; in the other there is more resemblance to 

 T. conspersa. I may add that in conspersa I have reason to believe 

 that, in the branched inferior appendages of the <$ , one branch is 

 mobile and capable of extension in a thumb-like manner.

DRAGON-FLIES (INCLUDING 1SCHNURA PUMILIO AND AORION 

 MERCURIALS IN ABUNDANCE) AND OTHER NEUROPTERA 

 IN THE NEW FOREST. 



BY GEO. T. POttKITT, F.L.S. 



From June 18th to July 1st last I spent at Brockenhurst in 

 company with Mr. T. Ashton Lofthouse, of Middlesbrough. The 

 immediate object of my own visit was to collect Ischnura pumilio, 

 Agrion mercuriale, and other New Forest dragon-flies ; but Mr. Loft- 

 house devoted bis time to the Lepidoptera. Acting on instructions 

 kindly given to me by Mr. W. J. Lucas, the morning after our arrival 

 I readily found the locality for Isch. pumilio and Agrion mercuriale, 

 and very soon saw that both species were in abundance, and they 

 became still more so in better weather a few clays later. I could 

 indeed have taken almost any number had I wanted them. Both 

 species flew together, though, as Mr. Lucas had already recorded, 

 pumilio seemed more partial to swampy ground, whereas mercuriale, 

 although also occurring freely in the swamp, was perhaps more plenti- 

 ful on the clear streams which ran through the boggy ground. 



The bright orange-yellow variety, aurantiaca,oi the ? of pumilio, 

 seemed much more plentiful than what is considered the ordinary 

 form of the $ , and was very pretty. A few Agrion puella occurred 

 among the mercuriale, but it did not take long to enable one to detect 

 the difference, even when on the wing ; and although an occasional 

 Isch. elegans occurred with the pumilio, it was quite a rarity on that 

 piece of ground, which I may add was of considerable area. Another
