externomedian veins run down the middle of the wing in a nearly 
straight course with oppositely diverging branches, to be}^ond the 
middle of the wing, when the scapular curves upward, terminating 
above the tip of the wing ; it emits several branches, the basal ones 
of which are compound, the middle ones forked and the apical sim- 
ple. The externomedian vein forks once near the middle of the wing, 
each of the forks being compound, the branches curved slightly 
downward apically and occupying but little more than the tip of the 
wing ; for the internomedian vein reaches far out toward the tip, its 
branches longitudinally oblique, the proximal ones simple, arcu- 
ate, their convexity toward the base, the distal ones forked, sinu- 
ate. The anal furrow is scarcely impressed, very little arcuate, 
reaching out over a little more than the basal third of the wing. 
The wing was apparently nearly three times as long as broad ; 
its length having been probably 24 mm. (though the fragment is 
only 21 mm.) and its breadth is 8.5 mm. It was discovered by 
Mr. Sam. Huston in the barren coal measures of Richmond, Jeffer- 
son Co., Ohio.

A single and rather fragmentary wing has some characteristics 
which are so clearly different from the others that it may be de- 
scribed, though imperfectly, as distinct. It shows the greater part 
of the apical half of the wing, in such a way that the main veins 
can be clearly separated. The mediastinal vein terminates at a 
point which is evidently more than half-way and probably two- 
thirds way down the wing, enclosing a rather narrow area and emit- 
ting simple, straight, moderately distant, oblique branches. The 
scapular is peculiar, being very straight and apparently terminating 
above the tip of the wing ; it emits its first branch only a little be- 
fore the end of the mediastinal at what must be about the middle 
of the wing ; this branch runs parallel to the mediastinal vein and 
forks just before the tip of the same ; the second branch arises 
very shortly after the first, runs parallel to the main vein and emits 
several very oblique straight branches (their tips are lost) running 
parallel to the mediastinal branches ; on account of the closeness 
of this second branch to the main vein, the thir^ branch only arises 
a long distance out. The externomedian vein branches opposite 
the termination of the mediastinal, and the forks or at any rate the 
lower again divide some distance beyond. The internomedian 
vein in the portion seen, which includes neither the basal half nor
