Phora {AphiochcBta) pleuralis, Wood ? 



St Abb's Head: a great swarm on 30th June 1914. The light- 

 keeper's description of the occurrence is as follows : — " On the 

 morning of the 30th June we had millions upon millions of a 

 strange little fly hovering about here. I never saw anything like it. 

 You could here them humming in the air at a distance. They were 

 everywhere; outside and in the houses, just fairly swarming" 

 (J. Moore, in lit. 5, vii. 14). A score of the flies sent to me are 

 Phorids {Aphiochceta). They are not in good condition for deter- 

 mination, but Mr J. E. Collin, who has kindly examined a couple 

 of them, thinks they are possibly A. pleuralis, Wood.

 Another specimen of this wasp was received from the Bass 

 Lighthouse in 1908, but I do not know whether it was taken at 

 38 F
