M. dimidiata, Staeg. This is apparently the Mycothera 
figured by Winnertz, but if so, his specimen had an abnor- 
mally short fork to the fifth vein. It is very common here 
and varies in the intensity of its wing markings and also 
in the number of spines on the underside of the mid tibiae ; 
usually there is only one of the latter, but I have seen 
specimens with two and even three. 
*M. czizekii, Landr. . Two males and three females from 
Logie (F.J.), and a female from Nethy Bridge (D.S.) 
must, I think, be this species. They agree exactly with 
Landrock’s description and figures (Wien. ent. Zeit. 1911, 
p. 165), except that a distinct median ocellus is present. 
Herr Landrock informs me that in some of his specimens 
a median ocellus can be detected. It rather closely resem- 
bles M. dimidiata, but the pale oval near the tip of the 
wing is absent; there are two equal spines beneath the 
mid tibiae. This species much resembles M. sordida, Wulp ; 
it differs in the lighter, striped thorax. This and the next 
two species were placed by Mr. Jenkinson as _ possibly 
varieties of Epicypta punctum. 
*M. stylata, Dz. (Mycothera). Five specimens (1 3 49) 
from Logie (F.J.). I cannot detect the median ocellus in 
any of them. The species somewhat resembles the last, 
but the apical 2 of the wing is all darkened, the hind femora 
have a black line above, and the thorax is darker and rather 
more shining. 
*M. adumbrata, Mik. One female, Logie, 23, ix. ’05 (F.J.). 
This specimen diverges from Mik’s description in two 
respects : (1) it has three ocelli; (2) the fork of the fifth 
+ In these species the thorax is only somewhat shining.
