basal part of the fifth, however, remains, indicating that it is 
disappearing by reduction. The basal part of the cubitus and 
its earlier branches are very strong, while the distal part of the 
same area is very weak. The anal area seems to have been 
easily detached and is seldom preserved in place. It was of 
medium extent. About twelve anal veins are present, the first — 
three of which occupy one-half of the area, while the last six 
or seven are crowded toward the inner border.

Etoblattina pecta sp. nov. Pl. LXXIII, fig. 2. 
Costal border regularly arched. Subcostal area broad, main 
vein extending perhaps one-half the length of the wing, with 
numerous oblique superior branches. Radial area large, prob- 
ably reaching to the apex of the wing; first branch, given off 
some distance from the base, has three superior branches; the 
second branch is once forked; two other simple branches are 
given off. The media is probably free to the base, but lies 
very close to the radius. It remains simple beyond the basal 
third of the wing. Cubitus not strong, probably of medium 
extent. Anal furrow not distinct. 
One specimen only of this species is recognized. The wing 
membrane is thin, and the framework of veins rather light. 
The species can be readily distinguished from FE’. curta by the 
close approximation of the radius and media at the base, as 
well as by the branched first division of the radius, and the 
large extent of the radial area. Length estimated at 12 mm. 
A second specimen, No. 131, is referred with some doubt to 
this species. It is very similar in the close approximation of 
the main veins at the base. It is perhaps a little smaller, 
measuring 10 or 11 mm. long, 4 mm. wide. The first branch 
of the radius of this specimen is once branched only.
