Mr. F. W. Edwards’ Notes on British Mycetophilidae. 367 
*R. signatipes, Wulp. New Forest, Sept. 1904, 12 
(C.G.L.). 
*R. spinipes, Winn. -Logie (F.J.); Lelant (J.W.Y.); 
Salcombe (G.H.V.); New Forest (F.C.A.). 
*R. virens, Dz. Logie, Crowborough, Aldenham (I.J.); 
Felden (A.P.); Aviemore and Sheviock (J.W.Y.); New 
Forest (D.S.); Llangollen (G.H.V.); Nethy Bridge (D.8.). 
*R. domestica, Mg. Seems to be common. Logie, 
Cambridge, Crowborough (F.J.); Beattock, New Forest, 
Wells (C.G.L.); Aviemore, Spey Bridge, Sheviock, Lelant 
(J.W.Y.); Newmarket (G.H.V.); Westhide, Tarrington 
(J.-H. W.). 
*R. macrura, Winn. I regard as R. macrura a species 
very similar to R. domestica, but with quite different geni- 
talia, and with a short median pale line in front of the 
scutellum which R. domestica does not possess. I have 
seen the species from Logie (F.J.); New Forest (D.S. and 
C.G.L.); Felden (A.P.); Sheviock (J.W.Y.); Chippen- 
ham, Cambs. (G.H.V.); Nethy Bridge (D.8.); Stoke Wood

*R.connexa, Winn. Crowborough, 1 3 (F.J.); Bridgend, 
Glamorgan (J.W.Y.). 
*R. fovea, Dz. Logie, 1 g(F.J.). In this specimen the 
‘mediastinal vein ends in the subcostal, not freely between 
it and the costal. The general character and structure 
of the hypopygium, however, agree with Dziedzicki's 
description and figure. The same remarks apply to the 
Crowborough specimen of &. connexa. 
*R. placuda, Winn. Salcombe (G.H.V.). 
Autopia, Winn. 
(including Brachycampta, Winn.). 
A. crassicornis, Stann. Some very dark specimens from 
Velden and elsewhere evidently represent Winnertz’s 
A. obscura, having the flagellum of the antennae all black 
and the thorax blackish instead of reddish. The male 
hypopygium, however, is quite typical, and A. obscura may 
safely be regarded as a dark variety of A. crassicornis. 
A. lugens, Wied. (= ornaticollis, Mg.). This species 
perhaps shares with Exechia fungorum the position of being 
the commonest fungus-gnatin thiscountry. Itis extremely 
variable, especially in the abdomen, which ranges from 
entirely black to mainly yellow. No other fungus-gnat
