Distribution. 



Being of South luiropcan distribution, /'. toiclltmi 

 is a Dragonfl}- that we should not have expected to 

 find in England. Not onh' is it distinctly British, 

 however, but in some of its haunts it is ver}- plentiful. 

 Moreover, it certainly extends as far north as Cambridge, 

 and perhaps even farther still. In Siinry it has been 

 taken at Weybridge (R. McLachlan, 1^74) ; it is 

 abundant on Esher Common (\\ . J. L.), and has been 

 reported from ^lerton (J. S. Brocklesb}-;. In Hampshire 

 it occurs in many parts of the New- Forest (W. J. L.), 

 and at Bournemouth (R. C. Bradley;. In Sussex a 

 female was on one occasion taken near Liphook 

 (W. J. L.). H. Doubleda}', in 1871, said it was 

 formerly very common near Epping, in Essex ; and 

 De Selys ("Revue," 1850) gives Dorsei (Dale) as a 

 localit}-. In Cainbridgeshii e it occurs at Chippenham 

 Fen, commonl}-, and at W'icken Fen (G. T. Porritt) ; 

 while Mr. J. Arkle reports that at Abersoch, in 

 Laneashii\\ he once came across large numbers of 

 what he took to be small specimens of P. iiyiiiplinla. 

 On seeing a series of P. teuelliiui, he felt that he had 

 made a mistake, and that the insects belonged to 

 the latter species. He, however, had no specimens 

 to confirm his supposition, so this northern locality is 

 at present onl)- conjectural. His description of the 

 habits of the insects, howexer, seems to point to the 

 more interesting species.
