Schizoblattina minor sp. nov. 
Subcostal area well developed, broad at the base, reaching 
somewhat beyond the middle of the wing. Branches few, 
mostly simple. Radius dividing about the middle of the wing, 
the upper division simple, the lower dividing once or twice, the 
branches falling a little short of the apex. The media divides 
before reaching the middle of the wing, the branches running 
apparently to the apex and to the inner border. The cubitus 
branches early and is of moderate extent. Estimated length 
of tegmina, 13 or 14 mm.; breadth, 5 or 6 mm. 
The species is much smaller and the veins of the wing fewer 
than those of the type of the genus. The one specimen of the 
species found is contained in a fine-grained clay, which, un- 
fortunately, on account of being near the surface, has become 
much water-soaked, so that the impression of the wing is dim 
and the cross-veins if present fail to appear.

Schizoblattina schucherti sp. nov. Pl. LXX, fig. 7. 
The Yale collection contains a third species of this genus. 
The humeral angle, as is usual with the genus, is square and 
very prominent. The subcostal area is broad, but short, reach- 
ing hardly half the length of the wing. Four branches arise 
from the subcosta, the first three of which are forked in the 
type specimen. The radius gives off its first branch at the 
termination of the basal fourth of the wing. The radial area 
probably reaches to the apex. The median area is narrow. 
The first branch is given off opposite the end of the anal area 
and is twice forked. Two or three other forked branches are 
given off. The main vein is strongly curved and meets the 
inner border only a little beyond the middle of the wing. The 
cubitus is short, curved, and runs along parallel to the media, 
meeting the inner border just beyond the middle line of the 
wing. The cubital branches are heavy but flexuous. The first 
two end on the anal furrow. The following are simple and 
run to the inner border. Cross-veins are fewer than in the 
type of the genus. They are seen best developed in the central 
part of the wing, uniting the branches of the media. The 
anal area is unknown. Length estimated at 11 to 12 mm.; 
breadth, 4 to 414 mm. , . 
The species differs from S. multinervia in the fewer
