Etoblattina strigosa, nov. sp. 
A single specimen represents this species, the form of which was 
probably as slender as the others, but the tip and lower outer por- 
tion is lost, which is the more unfortunate that they appear to 
have been peculiar. The costal margin is as convex as in E. 
Jiustoni, but the wing, to judge by the neuration, was much slen- 
derer than in that species. Presuming it to have been about three 
times as long as broad, the mediastinal area must have extended 
over nearly two-thirds of the wing, as a tolerably narrow belt with 
numerous straight and oblique veins. The scapular vein must 
have terminated just above the apex of the wing, and commencing 
to branch near the middle of the basal half of the wing emitted 
numerous rather crowded, long and very longitudinal, generally 
forking branches to the margin. The externomedian vein, so far 
as it can be traced on the fragment, which must include more than 
two-thirds its course, is an undivided vein, so that it must in any 
case be insignificant ; while on the other hand the internomedian 
vein plays a very important part. Shortly after it parts from 
the immediate proximity of the anal furrow it sends out an inferior 
branch, which runs in a nearly straight course parallel to the main 
stem and to the externomedian vein, and terminates at some con- 
siderable distance beyond the mediastinal vein ; from it, and not 
from the main vein, arise the usual oblique offshoots, which are few 
in number, distant, nearly straight and oblique ; the main vein again 
forks at about opposite the tip of the mediastinal, but, by emitting 
a superior vein which parts rather widely from the parent stem, 
evidently continues the course of the internomedian vein to an 
unusual distance toward the apex ; but here the wing is unfortu- 
nately broken. The anal furrow is very strongly arcuate, not deeply 
impressed, and terminates before the end of the basal third of the 
wing ; the area is filled with subparallel, mostly simple veins, near 
the furrow parallel to it, farther from it less so, until they are some- 
what crowded and nearly straight next the lower inner angle.
