376 Mr. F. W. Edwards’ Notes on British Mycetophilidae. 
vein is distinctly shorter, though not narrower. Both these 
characters are known to be variable in some species. 
M. adumbrata has a superficial resemblance to #. punctum, 
but the costa does not extend beyond the third vein, and 
the hind femora are dark only at the apex. 
M. unicolor, Stan. Of the typical form of this species, 
with a central wing-spot, I have only seen a single male 
(Cambridge, 2. xi. ’03, F.J.). See notes under Hpicypta 
scatophora. 
*M. formosa, Lundstr. (= pulchra, Lundstr.). This very 
distinct species has occurred at Inveran and Colwich Park 
(G.H.V.); Crowborough (F.J.); New Forest (F.J., D.S., and 
C.G.L.) Lundstrém’s M. pulchra seems to have been 
described from a dark female of this species. 
*M. nebulosa, Stan.? What I cannot but regard as this 
species is represented by a good number of specimens from 
Logie and Crowborough (F.J.), two from the New Forest 
(D.S. and C.G.L.), and one from Aviemore (J.W.Y.). In 
dark specimens the apical wing-fascia which includes a 
pale spot (somewhat as in M. dimidiata), reaches the hind 
margin, and there is a distinct brown blotch in the anal 
cell, these points not being observed by Winnertz. But 
the wing-markings vary a good deal in intensity and some 
specimens answer fairly closely to Winnertz’s description. 
The hind femora are broadly brown at the apex, which also 
is not mentioned by Winnertz. So far as I have observed, 
there are only two ocelli. The wing-markings of the 
palest specimens resemble those of M. vittipes. Hypo- 
pygium, figs. 79 and 80. 
M. vittipes, Zett. This seems to be rather common. In 
every one of 35 examples which I have examined micro- 
scopically, three ocelli are present. There are two forms, 
which may perhaps prove to be distinct species : (1) wings 
and coxae yellower, thorax with two large yellowish 
shoulder-patches, wing not darkened round apex ; (2) wings 
and coxae greyer, thorax only very narrowly yellow on the 
front margin, wing darkened round apex. ‘The latter form 
is the true M. wittipes; the former has been described 
(evidently by mistake) by Dziedzicki as M. gibba, Winn. 
M. stolida, Wik. The type (a male) is fortunately still 
in existence and is in fairly good condition. A large series ~ 
has been taken in the New Forest by Dr. Sharp and Mr. 
C.G. Lamb. There is frequently a fairly distinct pre-apical 
wing-spot, as well as the central spot on the cross-vein.
