Distribution . — Trenton Falls and Wihnurt, New York. 
The female formerly called Ft. proteus is here renamed Ft. 
comstocki. 
9 . — Length to tip of wings, o2 rnm.; expanse of wings, 70 mm. (Newman’s 
Pi. proteus type). 
Head a little narrower than the prothorax. Prothorax slightly widened 
posteriorly; sides and front border straight; posterior margin convex; angles 
right; a light triangular spot on median anterior border. Venter of thorax 
varied with pale markings, posterior margin of the first seven sternites bordered 
with a narrow, pale band, the eighth, except for the tip, and ninth entirely 
light. 
Female. Eighth ventral segment somewhat triangularly produced with a 
small, median, rectangular, apical notch. The incision has not been noted in 
previous descriptions, but since it is very inconspicuous, we do not regard it, 
at present, as a species distinct from that originally described under Pi. 
proteus (fig. 15). 
Type . — A single pinned specimen in poor condition (faded, 
having once been in alcohol, and with broken wings), from 
Wihnurt, New York, (Comstock), in the entomological collection, 
at Cornell University, Ithaca, New York. 
Male unknown. 
Nymph unknown.

Adult 
This is a western genus similar to Fteronarcys , but smaller. 
There are other characters as distinctive as the size; the vena- 
tion is reticulate (fig. 58) but the cross-veins are fewer and more 
regular, in the fore-wing the cell between the basal part of radius 
and media is without cross-veins, cubitus has no accessory veins; 
the supra-antennal plate is not well developed; the angles of the 
prothorax are not produced; and the genitalia are of quite a 
different character. 
Color, dark brown, varied with darker and lighter markings. 
Head as broad as prothorax; ocelli well developed, forming an 
equilateral triangle; a blackish rectangular spot across the ocellar 
triangle, on either side lieyond the blackish area a pale, flattened 
tubercle, anterior to it, the lateral margin carinated; antennae 
slender.
