the wing, and under this, more or less concealed, a vitrifying of the discal 
space. This vitrifaction essentially modifies the venation ; the cross vein 
on the outer margin of the discal cell is lost from its place, and vein 6 
continues almost to the base, to which place the outer discal vein seems 
to be forced. The vitrifaction is both sides vein 6, and this is pushed out 
by the spaces in waves back and forth. The costal and subcostal veins 
are strongly modified, being driven together, and having the appearance 
of anastomosing. The costal space is broadened basally. The lower 
median is extraordinarily broadened, especially at and beyond the union _ 
with vein 2, where it is swollen and seems to be filled with a liquid in 
color and appearance much like that which exudes from the wings when 
punctured during expansion. We are confident the insect can at will 
expand the tuftings of the maxillary palpi, and can project forward the 
costal scale fold, and expose the vitreous space, and can thus with its 
bitufted antennz and movable scaled process added, far beyond the ord- 
inary ability of the Lepidoptera, flaunt its beauty peacock-like before its 
mate for the sake of gaining her admiration and becoming her choice 
in love. 
Another peculiarity of the wings is a patch of short stiff hairs at the 
base of the fore wings between vein 1 and the inner margin. 
Still another peculiarity is the frenulum which is single in the male, 
divided in the female. 
Vein I is sometimes furcate near the base, sometimes not, in the 
same species. No reliance can be placed upon this peculiarity for 
generic determination. ‘This is the only point of structure which gives 
any suggestion of relationship to the Gad/erudae. 
In a few instances we have found veins 4 and 5 of the fore wings, 
after separation from the angle, joined again, forming a cell. This is, 
however, a characteristic not permanent to the species. 
Still another very extraordinary characteristic is the existence in 
some species of 11 veins only in the fore wings of the ©‘, while the 9 
has 12. From very careful observations upon finely prepared specimens, 
we are of the opinion that this is due to the coalescing of 10 and 11 
through the modification caused by the vitrified space. Jn the 11-veined 
females, the same thing has happened from other causes. With Mr. 
Meyrick we agree that no vein is ordinarily lost, save by coalescing 
with another, the point of furcation being moved beyond the edge of the 
wing. 
Still another peculiarity is the strong tendency to iridescence on the 
posterior portion of the fore wings beneath. It is ordinarily apparent as 
a mother of pearl lusrer, but under a strong glass with very strong light 
it shows out with a splendor we have rarely or never seen surpassed.
