Handlirsch identified as an eye is plant material, like 
that covering most of the nodule. There is therefore no 
evidence whatever that the wing-pads of this insect were 
developed perpendicularly to the thorax. The wing it- 
self, however, shows more details than are indicated 
in Handlirsch ’s figure or description. It is about 7 mm. 
long, with an anterior margin that is slightly concave 
proximally and convex near the middle. The most ob- . 
vious feature of the wing is a prominent longitudinal 
ridge (or groove, in the counterpart), which is probably 
the radius (Rl). Between it and the anterior margin is 
a weaker interrupted ridge, and posterior to it is what 
appears to be a forked vein. There is also a suggestion 
of a posterior submarginal vein. 
The part of the abdomen that is preserved consists of 
five or six broad segments. These few segments indicate 
an abdomen that is large in proportion to the wing, — a 
peculiarity suggesting that the insect was a nymph. 
This was probably the case, but there is another possi- 
bility worth mentioning: the wing of the fossil is much 
like the elytron of some Protelytroptera, even to the con- 
cave anterior margin, the heavy Rl, and the posterior, 
submarginal vein. Without more precise knowledge of 
the fore wing and at least part of the hind wing, we can 
reach no conclusion on the ordinal position of this fos- 
sil. There is certainly nothing to show that it is pakeo- 
dictyopterous, and Handlirsch, although describing the 
specimen as a nymph of that order, gave no reason for 
his conclusion.

The type of this species is preserved in black shale, 
from soft coal beds near Redbird, West Virginia, and is 
now in the National Museum (No. 25635). Handlirsch ’s 
drawing of the fossil is reproduced here (plate 6, figure
