the third forked near the base (possibly again at tip, where the 
wing is broken), the fourth and probably the second simple ; this 
arrangement of the scapular veins does not differ in any essential 
feature from that of Etoblattina russoma; indeed it bears a 
striking res-emblance to it ; while the disposition of the veins 
of the right wing closely recalls that of the veins in Eto- 
blattina carbonaria, for here there are five veins present (possibly 
a sixth may be given off in the broken apex) which are tolerably 
approximate and either simple or simply forked, the first two 
being narrowly forked near the middle, the others simple so far 
as they can be traced ; the general course of the main vein and 
the extent of its area is very similar in all three of these species. 
The externomedian vein has a pretty strongly and pretty regu- 
larly sinuate course, being regularly and strongly arcuate in its 
simple basal half, in which it reaches the very centre of the wing, 
then becomes more and more longitudinal, terminating slightly 
further below the tip than the scapular vein above it ; in its basal 
third it is closely appressed to the scapular vein and first begins 
to part from it opposite the first branches of the mediastinal vein ; 
it first forks a little before the middle of the wing (a little 
sooner on the right wing than on the left, viz., at the end of the 
second fifth of the wing), and emits four usually simple, equidis- 
tant, longitudinal branches ; in the right wing one of these, the 
third, forks near the base, and probably the same is the case in the 
left wing. The internomedian takes a course parallel to the exter- 
nomedian vein, but is a little less strongly sinuate and is moder- 
ately distant from it ; it emits from seven to nine generally simple, 
slightly curving branches, the basal ones very oblique, beyond 
becoming more and more longitudinal, so that the area is consid- 
erably produced toward the tip ; the basal branch is emitted just 
before the middle of the basal half of the wing, and is forked, 
singly on the left, doubly on the right wing ; the only other forked 
veins are at the apex, where the last one, on the left wing, is 
forked ; the left further differs from the right wing in the greater 
number of branches to this vein and by the upward thrust of 
the termination of the vein beyond its final branch. The anal 
furrow is strongly arcuate and terminates at the end of the basal 
third of the wing; the anal veins, six or eight in number, are
