The genus differs from Notodonta iii the more strongly x)ectinated antennm, in the more 
pointed, less rounded wings, and in the venation. The paljii are nearly the same.

Moth . — Two 5. Head, pali)i, and jirothoracic collar vandyke-brown^ the front x>art of the 
thorax contrasting with the mouse-gray hinder iiortion. Fore wings uniform ash-gray; no 
distinct transverse line at the base, but just before the middle of the wing are three vandyke- 
browu x)arallel close-set lines which begin on the costa, but are most distinct and heavj^ between 
the subcostal vein and above the median fold; the outermost and innermost of the tlu^ee lines 
extend to the inner edge of the iving, but the middle one is obsolete. The outermost of the three 
lines is situated very near the dark vandyke-brown, distinct, curvi- 
linear discal spot, and this distinguishes the species from any other 
Notodontian. On the outer fourth of the wing are two faint scal- 
loped dark lines, represented by venular dots; a marginal row of 
irregular brown spots. 
Hind wings and abdomen dark ash-gray, and both pairs of wings 
beneath of the same hue. The underside of the costa is not check- 
ered with liglit and dark spots, as it is in Sclii/aira and other genera. 
Expanse of wings, 3 37-12 mm.; length of body, ^ 15 mm. 
At first this species might be mistaken for a variety of ^chmira 
leptinoulefi, as the shape of the wing, the discal spot, and the Hues 
are similar, but in no other species is the linear dark discal spot 
situated so near the transverse lines, these three lines being heavier 
and most distinct in the middle of the wing. Also the dark brown 
collar is i)eculiar, the thorax not being tufted. The pectinated $ 
antenme will separate the genus from any excex)t Notodonta, to which it is nearest allied. 
Professor Smith includes this genus in the Noctuidje, i»lacing it in Bombycia, but its venation 
is that of the Notoilontiiue, as it has but three branches of the cubital vein, and the subcostal 
venules are as in the Notodoutium. lie also remarks: ‘‘The ty|)e is in the Saunders collection at 
Oxford, England. A figure sent mo by ^Ir. Schaus proves it to be ^Ldema iransversata 
Ellida (jelida Grt.’” (Oat. Noctuidic, p, 21), 181)3.)

Moth . — Head moderately prominent; front stpiarish, moderately broad, the scales on it evenly 
cut, rather short; the tuft at the base of each antenna rather prominent. Antenna*- not quite half 
as long as the fore wings, and in 5 well i)ectinated to the ti^is; the branches four times as long as
