Mr. F. W. Edwards’ Notes on British Mycetophilidae. 377 
There are a pair of yellow patches one on each side in front 
of the seutellum, but the scutellum itself is entirely black. 
M. luctuosa, Mg. One male from Crowborough (F.J.) 
shows a remarkable abnormality in the venation: the 
fork of the fourth vein of one wing is divided into two 
by a cross-vein about the middle, the two branches being 
drawn in so as to form an oval cell somewhat like that of 
Synapha. 
M. obscura, Dz. Tuddenham, Boyton (G.H.V.); Crow- 
borough (F.J.). This seems to me to be probably only a 
dark variety of M. lwnata, Mg. (Winn.), as the hypopygia 
are practically identical. 
*M. fuliginosa, Dz. Mildenhall and Tottington (J.W.Y.,) ; 
Felden (A.P.); Dunphail (F.J.). 
*M. blanda, Winn. Logie, Boat 0’ Garten, Cambridge, 
Crowborough (F.J.); New Forest (D.8., C.G.L.). The 
brown cloud in the anal cell is absent in most of the British 
specimens I have seen, but some Dr. Lundstrém sent me 
from Finland have it very distinctly. 
*M. tarsata, Winn. Westhide, 1 3 (J.H.W.). 
*M. curviseta, Lundstr. Ply mbridge (G. C. Bignell) ; 
Southern Down and Bridgend, Glamorgan (JAW. ¥i2)5 
Felden (A.P.); Westhide (J.H.W.—in this specimen the 
blotch in the anal cell is wanting). ~ 
*M. spectabilis, Winn. Dolgelley, Bettws-y-Coed, Ug- 
brooke, Lyndhurst (G.H.V.); Felden (A.P.); | Sheviock 
(J.W.Y.); Crowborough (F.J.); New Forest (D.S., 
C.G.L.); Haugh Wood and Stoke Wood, Hereford 
(J.H.W.). 
*M. marginata, Winn. This seems to be one of the 
commonest species. 
*M. fraterna, Winn. Logie (F.J.); Lelant (J.W.Y.); 
Bettws-y-Coed (G.H.V.). 
*M. finlandica nom. n. (Dziedzicki, MS.—lunata, 
Lundstr. nec Mg.). Nethy Bridge (C.G.L.); Logie and 
Crowborough (F.J.); Bettws-y-Coed (G.H.V.); New 
Forest (D.S.); Stoke Wood (J.H.W.). 
*M. confluens, Dz. New Forest and Nethy Bridge (D.8.) ; 
Aviemore (J.W.Y.). 
*M. sigillata, Dz. Bettws-y-Coed (G.H.V.). 
*M. signatoides, Dz. New Forest (D.S.); Crowborough 
(F.J.); Iken, Lelant (J.W.Y.); Felden (A.P.); Llan- 
gollen, Bettws- y-Coed, Rydal, Newmarket, Stoke Wood,
