8. B. serenajWinn. : this species also has occurred in my garden, 

 and in the other end of this parish of Exning, besides some doubtful 

 female specimens from Three Bridges and Bettws-y-Coed. Although 

 I cannot positively separate the females in this genus, I can form a 

 somewhat strong opinion as to the species which they represent. 



9. B. amosna, Winn. : apparently a common species in June and 

 July, at any rate about the Lake District and North Wales, and also 

 occurring at Lyndhurst. 



10. B. hastata, Winn. : a very well marked species, of which two 

 males were caught by me at Wyre Forest on September 4th, 1892. 



IL. B. griseicollis, Stseg. : another species apparently common 

 from July to October in my garden, and at Dolgelley. 



12. ExecJiia tenuicornis, v. d. Wulp : an undoubted male at Wyre 

 Forest on September 4th, 1892, besides several females. 



13. E. interrupta, Ztt. : this species occurs in my garden in 

 September. 



14. E. spinigera, Winn. : specimens of what I believe to be this 

 species have been caught by me more than once in my garden, and 

 also at Rydal on June 19th, 1889. 



15. Anatella ciliata, Winn. : I think there can be no doubt but 

 that I caught a male of this species at Dolgelley on July 26th, 1888. 



16. PJironia basalts, Winn. : when I published my " List " I be- 

 lieved at least a dozen species of this genus occurred in Britain, but 

 I could not identify them ; of the two I accepted then I now know 

 nothing more about P. nitidiventris, v. d. Wulp, while P. austriaca, 

 Winn., although correctly identified by me, is only the female of P. 

 signata, Winn., which, has occurred abundantly at Inveran and Bettws- 

 y-Coed. I believe I now possess at least eighteen species of the genus, 

 and with considerable confidence I introduce seven as British, of which 

 P. hasalis is the first ; this seems to me an unmistakable species, which 

 I caught freely at Dolgelley in June and July, and also at Lyndhurst. 



17. P. cinerascens, Winn. : abundant at Lodore on June 21st, 

 1889. 



18. P.forcipula, Winn. : common from Plymouth to Inveran. 



19. P. crassipes, Winn. : common at Colwich in June, 1889. 



20. P. Girschneri, Dzied. : I cannot doubt but that I have caught 

 this remarkable species in my garden on September 18th, 1888, and 

 also at Dolgelley on July 25th, 1888.
