NOTES ON BRITISH PHORA (Corrections and Additions), 



BY JOHN H. WOOD, M.B.

(Plate V). 



GrROUP I OF BbCKEE. 



Since Becker wrote, his Group I has been conveniently divided 

 into two genera, based mainly on the condition of the second thick vein, 

 the tenn Phora being restricted to the species in which the vein is 

 forked, and that of Hypocera, Lioy, given to those in which it is 

 unforked. 



Phora gracilis. This was described from the female only. Since 

 then I have on several occasions found the male on the trunks of 

 beech trees, paired with the female. It is markedly smaller than its 

 partner and barely exceeds 1 nun. in measurement, but needs no 

 separate description. The hypopygium is very similar to that of 

 rmisjnnosa, and consists of a very long and narrow flap on each side 

 and a small papilla-like anal organ.
