372 Mr. F. W. Edwards’ Notes on British Mycetophilidae. 
besetzten Lamellen;’’ he does not refer to H. scatophora, 
but it 1s fairly evident that he had Perris’s insect before him. 
The fact that the larvae of H. scatophora and E. trinotata 
agree in their remarkable habits may show that they really 
belong to the same genus, but as Strobl definitely states 
that “ die Randader geht nicht iiber die Miindung derdritten 
Langsader,” it is difficult to see |how the species can be 
kept in Epicypta. Increased knowledge may of course 
show that the larvae of other species of Mz ycetophila form 
the same peculiar limpet-like cases. 
In the other species, with the very small hypopygium, 
the costa does not extend beyond the third vein, and the 
median ocellus is absent, so that there is really nothing to 
exclude it from Mycetophila. In fact, I have been unable 
to detect any difference between the hypopygium of this 
species and that of M. wnicolor, although Lundstrom has 
just described the form under consideration as a distinct 
species (M. posticalis) ; very probably E. scatophora, Winn., 
is only a variety of M. unicolor, Stan., without the central 
wing-spot. If the female of MM. wnicolor should prove to 
have the two long hairs on the ventral side of the second 
abdominal segment, the specific identity of the two would 
be fairly well established. These hairs are not present in 
the male sex; the specimen referred to by Mr. Jenkinson 
as taken at Cambridge, 24. vii. 1904, is really a male of 
this species, and I have seen another from Crowborough, 
5, vin. 1912 (F.J.). 
The synonymy of the two may stand as follows :— 
1. Mycetophila scatophora, Perris (1849). 
? Mycetophila aterrima, 9, Zett. (1852). 
Epicypta aterrima, 3, Strobl. (1894). 
Mycetophila unicolor, Stan., var. posticalis. 
Kypicypta scatophora, Winnertz, Jenkinson. 
Mycetophila posticalis, Lundstr, (1912). 
Myceropuina, Mg. 
(including Mycothera, Winn.) 
Since Lundstrém has found that the occurrence of a 
median ocellus is not constant even within the limits of a 
species, and as it is found in several species which have 
been included in Mycetophila, the genus Mycothera cannot 
be maintained; the type species (MW. dimadiata, Staeg.)
