what beyond the middle. The main vein and its branches fill 
the apex. The cubitus varies in extent, either reaching well 
onto the apical margin, its greatest extent being obtained by 
an outward curve near the termination, or, lacking the curve, 
ending short of the apical margin. The first five or six 
branches are straight, mostly simple, and parallel; the others 
are more oblique, not uniform in number, curved and some- 
times forked. The anal area extends approximately to the 
end of the basal fourth, is clearly marked off, and has six or 
seven mostly simple veins. The main veins of the wing orig- 
inate close together somewhat above the middle of the base. 
The veins diverge in the central part, enclosing elongate light- 
colored areas. The tegmina are delicate and thin, the veins 
thin, although appearing heavy in places because of the dark- 
colored bands accompanying them. The alternate dark and 
light areas give the wing a variegated appearance. A dark 
band extends along the costal border, obscuring the tips of the 
veins. Similar bands accompany the radius, media and cubitus. 
Light areas occur between the interspaces of the main veins, 
as well as between some of the principal branches. Two con- 
spicuous, large, light spots occur in the apical part of the 
wing. The agreement with the types of the species is very 
close. The two light spots on the apical part of the tegmina 
are not described for the type, probably because the apex was 
not well preserved. | 
The hind wings are thin and ovate in shape. The costa is 
submarginal, straight and simple, reaching about one-third 
the length of.the wing. The subcosta lies at the bottom of 
the subcostal fold, gives off a few oblique, short superior © 
branches beyond the termination of the costa, and reaches 
somewhat beyond the middle of the wing. The radius reaches 
nearly to the apex and gives off one to three very oblique 
simple or forked branches. The media has four or five superior 
branches which fill the apex. The media continues independent 
almost or quite to the base. The cubital area is well developed, 
the branches very oblique, simple, straight, parallel. The first 
anal vein is simple. Beyond the first anal are seen a few 
simple or forked veins. . Eleven hind wings of this species have 
been obtained, one in direct connection with the tegmina. The 
hind wing is of even thinner texture than the front, and has, 
like the front wing, light and dark areas. A dark area extends
