stout, black, bristle-like hairs. The two wings smoky 
grey, fringed at the edges with long fine hairs, and 
sprinkled over the surface with hairs, and also with 
ribbed scales, resembling one of the forms found on 
butterflies’ wings. The wing-veins all ran lengthwise, 
the first almost close to the front margin of the wing, 
running parallel to it, and uniting with it about half¬ 
way down ; the second running straight along the wing 
at rather less than one-third of the whole width of the 
wing from the front, until near its termination at the tip 
of the wing it curved slightly backwards ; the third vein 
(placed about the width above mentioned from the 
hinder margin) runs almost straight, ending at the 
hinder margin about one-quarter of the length of the 
wing from its tip; this third vein throws 
out a side-branch, w T hicli curves backwards 
to the hinder margin of the wing exactly 
opposite the termination of the first vein. 
Legs very long and fine, yellowish brown, 
hairy ; uppermost joint of tarsi very short. 
Eyes black; antennae beaded, long, and 
hairy. The two basal joints shorter and 
wider than the succeeding beads. The 
remainder of these up to the apical joint 
(with the exception of those immediately succeeding the 
basal joints)* were rather longer than wide, apparently 
cylindrical in form, and slightly contracted at the middle; 
the terminal joint was bluntly pointed and about as 
long again as the preceding bead. These joints were at 
first distinctly stalked, so that, excepting towards the 
end of the antenna, they could be seen to be distinctly 
separated. From the minuteness of the division, and 
also as with maturity and death, the beads drew so 
nearly together as almost to appear to touch, I had 
great difficulty in counting them, but after repeated

* I unfortunately omitted to make a note of the precise form of these 
at the time ; from memory I should say they were like the corresponding 
joints of the male antennae, as figured by Dr. Packard, but not having 
figured and noted them at the time the observation may not be correct.
