the wing, and under this, more or Ic-s 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 hum 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 antennae 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 i 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 u[)on this peculiarity for 

 generic determination. This is the only point of structure which gives 

 any sugge>tion of relation>hip to die Galleriidae. 



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 characterisdc not permanent to the species. 



.Still another veiy extraordiitarv characteristic is the existence in 

 some species of i i veins oww in the lore wings of the (^, while the ^ 

 has 12. From very caiefiil ol)scrvations upon finely prepared s])ccimens, 

 we are of the opinion that this is due to the coalescing of 10 and 11 

 through the modification caused b)- the vitrified sjiace. In the i i-veined 

 females, the same thing has ha|)pened from other causes. With Mr. 

 INIeyrick 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 

 posteri(M- portion (^f the fore wings beneath. It is ordinarily apparent as 

 a moth T of pciiil liis'er, but under a strong glass with very strong light 

 it shows out with a s[ilendor we have rarely or never seen surpassed.
