﻿124 THE ENTOMOLOGIST. 



Therevidce. 



Psilocephala ardea, F. One specimen of this species was 

 taken by Mr. Bradley at Wyre Forest, near Birmingham, on 

 July 7th. This species is new to the British lists. 



Thereva plebeia,Jj. (lug ens). Dover. 



T. fulva, Mg. Dover. 



Scenopinidce. 



Scenopinus fenestrates, L. One from Birmingham. Last 

 year I took several in London, but this year not one has appeared, 

 though its natural habitat seems to be houses. 



Empidce. 



Empis lucida, Zett. Aberdeen. Not a common species, 

 though it seems to have been common there. 



JEilara maura, F. This species swarmed over a sheltered 

 stream at Staines on May 23rd last. I took over 1200 specimens 

 in a quarter of an hour, two or three strokes of the net being 

 sufficient to obtain a solid mass of flies at the bottom of it. 



Tachydromia candicans, Fall. Dover. 



Dolichopodid<s. 

 This group I have not studied, but I have recognised 

 Dolichopus brevipennis, Mg., from Birmingham. 

 Poecilobothrus nobilitatus, L. Wimbledon, July 12th ; not 

 uncommon over one clump of bushes. 

 Argyra diaphana, F. Birmingham. 



Lonchopteridce. 



Lonchoptera lutea, Pg. Wimbledon, July 12th. 



L. flavicauda, Mg. Staines, May 23rd. 



? L. trilineata, Zett. I took several specimens at Wimbledon 

 on July 12th of what appears to be this species. Mr. Verrall 

 does not give it in his list as British, so I should not like to 

 answer for its correct identification. 



Syrphidce. 



Pyrophcena rosarum, F. Birmingham. 



Xanthogramma citrofasciatum, DeG. Maidstone. 



Ascia podagrica, F. Dover. A specimen from Staines 

 appears to be A. dispar. 



Volucella inanis, L. Three from Birmingham. 



Sericomyia borealis, Fall. Birmingham. 



S. lappona, L. Ivybridge, May, June. 



Eristalis horticola, DeG. Plymouth, May 21st — July 4th. 



Criorhina oxyacanthce, Mg. Birmingham. 



Xylota abiens, Wied. One specimen of this rare species 

 from Birmingham.
