Although both base and apex of both specimens referred here 
are lost, the most complete one has so much preserved that we 
can determine almost all the essential features of the neuration 
and restore with much probability the form or at least the propor- 
tions of the wing, which could not have been much less than three 
times as long as broad, and was remarkable for the extraordinary 
straightness of the main veins. The mediastinal vein terminates 
scarcely beyond the middle of the wing and has numerous straight, 
gently oblique, simple branches. The scapular runs in a nearly 
direct course to a point scarcely above the apex of the wing, but 
curves upward slightly toward the tip, begins to branch before the 
middle of the basal half and emits half a dozen long, longitudinally 
oblique, gently curved branches most of which fork midway to- 
the margin. The externomedian runs in an even straighter course 
toward the lower portion of the apex and throws off beyond the mid- 
dle only a few nearly longitudinal and straight, and so far as can 
be seen, simple branches to the apex. The internomedian vein runs 
in a perfectly straight course parallel to and rather distant from the 
externomedian and emits distant, nearly straight, mostly simple, 
oblique branches to the border. The whole wing is piceous, but there 
are streaks of light brown which enliven the wing, falling in the 
interspaces between the principal veins and between the interno- 
median interspaces, i. e., in all the widest intervals. No anal area 
is preserved but it must be unusually short, or the wing even longer 
than has been estimated. 
The second fragment contains scarcely more than most of the 
internomedian area and does not differ from the larger fragment 
except that it is proportional^ larger. 
A third specimen from the same place and person showing only 
a bit of the front central portion of the wing apparently belongs 
here ; and, if so, indicates that the branching of the scapular may 
commence later and the mediastinal area preserve a greater breadth 
near to its termination.
