The length of the preserved fragment, measured from the inmost 
point of R to the outmost corner of the fore margin, is 16 mm. 
1 specimen. Northern slope of Fuur (poss. Min. Museum). 
Flatidæ. 
Ormenis furcata n. sp. 
Unfortunately the Clavus part of the wing is missing in the find, 
drawn tig. 13, but I refer it to the Flatidæ, on account of the rich 
ramification of Media, and the scanty ramification (only a single 
bifurcation) of Cubitus. In venation it agrees so well with the recent 
genus Ormenis that I have no doubt about this reference. 
The fact that Subcosta is bifurcate is of great value as a peculiar 
species character, as it is simple in recent species. This bifurcation is 
estimated to take place about midway on the wing. Radius and 
Subcosta issue from the same point of the basal cell. The posterior 
branch of Radius once more bifurcates near its base. The furcation 
of Media near its base is most characteristic, because it soon appears 
quadrifurcate, as only the anterior branch of each of its 3 bifurcations 
has bifurcated. 
Its secondary branches bend strongly downwards in their outmost 
parts, still curving slightly forwards at the very tip. Cubitus only 
once bifurcates, and the branches approach outwards. 
Between the secondary branches of Media can be seen some 
crossveinlike impressions in the stone, but I have not drawn any of
