Mr. F. W. Edwards’ Notes on British Mycetophilidae. 365 
*C. tenella, Zett. (= flavicauda, Winn.). Logie and Crow- 
borough (F.J.); Nethy Bridge (D.8.). 
C. flava, Staeg. I have seen only one recent specimen 
of this species (Bonchurch, G.H.V.), but there is a male in 
the Clifton collection in the British Museum, and Walker’s 
type of Mycetophila flava is evidently Coelosia flava, 
though now much discoloured. 
Leta, Mg. 
I very much doubt whether the three species (terminalis, 
Mg., variegata, Winn. and elegans, Winn.) are really distinct ; 
in any case I have only seen one distinct British species, 
which had better be known as terminalis, Mg. 
Docosia, Winn. 
D. valida, Winn. A female taken at Logie, 23. ix. 1904, 
by Mr. F. Jenkinson, appears to be a variety of this species. 
The legs and halteres are entirely blackish brown, as in 
D. morionella, Mik, but the yellowish pubescence extends 
on to the abdomen, and is not confined to the thorax and 
coxae. Other specimens from Stoke Wood (J.H.W.) have 
the legs almost all black; but in these the halteres are 
yellow. 
D. sciarina, Mg. The mediastinal vein (Sc.) in’ this 
species seems to be much more bristly than in D. valida. 
BRACHYPEZA, Winn. 
B. radiata, Jenk. One female from Dartford, Kent 
(J.W.Y.). 
*B. spuria, sp. n. (Verrall MS.). 
Flava ; thorace grisescente, vittis 3 obscuris subconfluentibus ; 
antennarum flagello vertice tarsisque fuscis, maris arliculis 3 ultimis 
tarsorum anticorum flexis, subpilosis; abdominis segmentis dorso 
fuscescentibus ; alis subhyalinis, immaculatis. 
3g. Head dark brown, frons yellowish; palpi and base of antennae 
yellow, flagellum brown. Thorax greyish-ochreous, with short 
yellowish pubescence and black bristles on the margin; mesonotum 
with three rather indistinct and almost united brown stripes. 
Pleurae ochreous-brown. Abdomen yellow-ochreous, segments 1-5 
with large triangular dark brown patches on the dorsum, the base of 
the triangle towards the base of each segment; sixth segment dark
