are relatively much less dense than in other species and which are 
oriented more perpendicularly to the axis of the wing. 
Hind wing: length 56 mm, width 16.5 mm. Anterior margin 
very slightly convex, posterior margin with a small convex curvature 
at CuP. Apical part short and broad, broadly rounded. R-rs area 
broad. Rs originating shortly before the mid-wing, with 4 branches. 
Anal area large with 5 veins, iA forking. Cross veins in subcostal 
area, r-m and m-cu areas relatively sparse and almost perpendicular 
to the wing axis. 
This species differs from all others in the genus by the smaller 
number of cross veins and by their arrangement on the wing. It is 
related to klebsi by its broadly rounded apex and forked iA.

Stenodictya fritschi Brongniart, 1893: 385, pi. 22, fig. 7; Handlirsch, 1906: 
65 pi. 8, fig. 24; Lameere, 1917: 158; Handlirsch, 1919: 3. 
This species was based by Brongniart on specimen 22-7, repre- 
sented by a fragment which does not show enough features to enable 
comparison with the other species of the genus. It is probably part 
of a hind wing; the length of the fragment is 38 mm, the width 
20 mm. The wing probably narrowed gradually towards the apex; 
the anal area had a forked iA. The species may be related to 
Stenodictya with broad wings, such as klebsi. 
Two additional fragments of hind wings are included in the 
collection at the Institut. These are too incomplete to justify 
formal description but figures of them are included here because 
they show a few features not noted in other species. One of these 
(figure 70) is a fragment (Stenodictya sp. A) which shows clearly 
the basal subcostal plate and the branching of 2A, which is prob- 
ably an individual variation. The anal area has 5 veins, iA is forked 
and 2A has three branches arising pectinately. Wing fragment 
37 mm long and 21 mm wide. 
The other specimen is a fragment of a hind wing ( Stenodictya 
sp. B), which I could not find in the Institut but which was 
photographed there by Dr. Carpenter in 1938. The accompanying 
drawing (Figure 71) was made from the photograph. Rs originates 
shortly before mid-wing, MP has one additional branch. The anal 
area is large with 6 veins and iA is forked twice. The archedictyon 
is irregular and dense.
