1870, seems to belong to this spec-ics. It luis llie rilia of llie lower 

 orbit pale, two basal joints and base of third joint of antennte reddish- 

 yellow, legs yellow, face silvery, cilia of the aluhc black, wings gi'cyish, 

 cubital and discoidal veins only slightly converging, the discoidal 

 ending almost in the tip of the wing, and the lamclLT of the hypo- 

 pygium blackish, pale at the base. 



O. ATROYiEENs, Lw. — On one of the Entomological Club days, I 

 caught a male of this species at Footscray. It is blackish-green, cilia 

 of the lower orbit black, face white, antennae all black, scutellum bare, 

 legs all black, bristly, front tibia? with a long bristle near the tip, hind 

 femora ciliated beneath with pale hairs, lamella} of the hypopygium 

 black, considerably jagged, wings very dark, cubital and discoidal veins 

 strongly converging. Size, nearly 2\ lines. 



G. AXousTiFBOXs, Stseg. — The female specime]i of this, which I 

 had caught myself, is now in G-ermany, and I have no memorandum 

 of its locality, but I think it was Eaunoch ; the species has the cilia of 

 the lower orbit black, the scutellum pubescent, the femora black and 

 is much smaller than G. cupreus, Fali., which is the only other species 

 with these characters. 



Gr. METALLicrs, Stan. — I caught this once abundantly in Epping 

 Forest on June IGth, 1S72, and soon after met with it in Plashett 

 Park, near Lewes, on August 4th. It is one of the species with black 

 cilia of the lower orbit, and pubescent scutellum, with pale legs, and 

 no black stigmatical swelling on the wings of the male ; it is much 

 larger than G. ccrosus, and has a white face and yellowi.sli lamelhe of 

 the hypopygium. 



Gr. iEROSUS, Fall., var. Daldbomi, Zett. — This variety of ccrosus is 

 common iu vScotland, it has the legs considerably darker than the 

 normal f(jrm, but does not seem to differ otherwise. 



G. ASSiMiLis, Stseg. — This species is closely allied to G. ccrosus, 

 but the male has a white face, and the cubital and discoidal veins 

 converge more. I have met with it sparingly at Rannoch, Lyndhurst, 

 Three Bridges, and Darenth. 



G. NANUS, Mcq. — I caught a few of lliis at Eeigate on July 5th, 

 1872.
