iuDor edge. Tlie discal linear black spot very distinct and prolonged obliquely to the subcostal 
vein, aud also extending to the origin of the first cubital venule, and from that point a black line 
extends outward along the venule, ending in one of the submarginal series of bright sulphur- 
yellow intervenular spots which are situated in the faintly marked dark lunules. A series of 
dark brown lunules at the base of the fringe, which is white, faintly checkered with dusky at 
the end of the lunules. 
Hind wings whitish, with a dark costal oblique streak near the apex. 
Underside of the fore wings whitish, with three oblique brown streaks on the outer fourth of 
the wing, just before the apex. 
Expanse of wings, S 28-30 mm,; length of body, 11 min. 
To show that the genus Litodonta is probably not well founded, it may be said that //. superha 
is very near it, and ditters mainly in the 5 antenme not having quite such long branches, and in 
the thorax and fore wings being washed with tawny yellow instead of sea-green,* and in having 
no submarginal yellow spots. Otherwise the two species are very closely allied, being of the 
same size and with the same shape of wings. The female has not yet occurred, so that we do not 
know the nature of the antenum in that sex. 
Habits , — It is two-brooded, as the moths were collected in Texas in April and May and also 
in July and August (Riley MS,), 
OeograjMcal distribution , — Thus far this interesting species is confined to the Southern States 
(Austroriparian subprovince), having occurred in Texas, where it has been collected by Belfrage, 
aud ill Punta Gorda, Charlotte Harbor, Fla. (Mrs. Slosson); Texas (U. S. Nat, Mus.); Texas 
(Boll, Mus. Comp, Zook); Texas (French).

Moth , — Five ^ , three 9 . Of a uniform pale cinereous, being of a faded appearance and with a 
faint greenish tinge, without any band or sfiots; or pale sea-green; dusted very minutely with ashen 
scales, or varying in the same brood to dark purplish gray, with transverse darker punctuated 
scalloped lines. Costa very straight, compared with that of M, marthesia, A faint series of pale 
longitudinal lines situated on the venules passing across the fore wings near their base. On the 
outer third of the wing is a rather irregular curved series of dark spots bordered externally with 
white; the ends of the venules are dark. With these exceptions there are no other markings, 
the moth thus difieriug notably from its cougeuers; no part of the wing is darker than another, 
aud it has a faded look in very fresh examples, which is very unique iii the genus. 
The head, palpi, pectus, and uuderside of the body in general are very pale clay and whitish 
yellowish. The hind wiogs are pale ashen whitish, in some cases with a straight mesial, obscure 
dark spot. 
^ Dr. Dyar writes that he believes that fresh superha are green, aud that the yellow tint is due to fading, as in 
H. hiundata.
