Mr. I. W. Edwards’ Noles on British Mycetophilidae. 359 
Museum by Mr. A. E. J. Carter. This very closely re- 
sembles iS. nigra, Landrock, except in the hypopygium. 
Dr. Bengtsson of Lund informs me that the one remaining 
specimen of Zetterstedt’s series has lost its abdomen, so 
that there is no possibility of verifying the determination. 
Hypopygium, figs. 46 and 47. 
*S. jenkinsoni, sp. n. 
Nigra, nitida ; palpis, antennis basi, halterum basi, coxvis pedi- 
busque flavis, tarsis fuscis ; venula transversali subcostali pone cellulam 
cubitalem anteriorem inseria. 
6 2. Head blackish; palpi yellow; antennae a little longer than 
the thorax, first two joints and basal half of third yellow, remainder 
blackish. Thorax shining black or black-brown, a little yellowish 
below the shoulders, clothed with rather sparse yellow pubescence. 
Abdomen black, rather shining, long and thin in the male, thicker 
in the female; pubescence yellowish. Hypopygium, fig. 57. Legs 
with the coxae, femora and tibiae yellow-ochreous; trochanters 
black; tarsi dark brown. Wings hyaline; the subcostal cross- 
vein is placed distinctly beyond the small cell, which is less rect- 
angular than in most species of the genus; fork of fourth vein 
sessile ; upper branch of fifth vein less curved at the base than usual. 
Halteres with a light ochreous stem and a black knob. Length 
5mm. 
Aldenham, Salop, 1 ¢ (type in British Museum—F'.J.) ; 
Logie, 1 $19 (F.J.). The position of the subcostal cross- 
vein and the dark knob of the halteres will distinguish this 
species from all those previously described. 
Empauta, Winn. 
FB. vitripennis, Mg. In Walker’s type of Mycetophila 
finalis (which is really this species) and in a specimen 
from Crowborough, 11. viii. 1906 (F.J.), the small cell is 
absent on one wing, while in one from Studland, Dorset 
(J.W.Y.), one from Crowborough, Sussex (F.J.), and a 
third from the New Forest (D.S.), it is wanting on both 
wings. In such cases the species can be recognised by the 
very characteristic elongate hypopygium.
