Motli. — Two S . Head, palpi, and prothoracic collar vaudyke brown, the front part of the 

 thorax contrasting witli the mou.se-gray hinder portion. Fore wings uniform ash-gray; no 

 di>tinct transverse line at the base, but just before the middle of the wing are three vandyke- 

 brown parallel close-set lines which begin on the costa, but are nmst distinct and iieavy between 

 the subcostal vein and above the median fold; the outermost and innermost of the three lines 

 e.\tcnd to the inner edge of the wing, Init the middle one is obsolete. The outermost of the three- 

 lines is situated veiy near the dark Vandyke brown, distinct, curvi- 

 linear discal spot, aiul tins distinguishes the species from any other 

 Notodontian. On the outer fourth of tiie wing are two faint seal- 

 Ioi)ed dark lines, represented by venular dots; a marginal row of 

 iri'egular 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 light and dark spots, as it is in Schizura and other genera. 



Expanse of wings, i 37-41} mm.; length of body, <? J.> mm. 



At first this species might be mistaken for a variety of Schizura 

 Icptiiwides; as the shape of the wing, the discal spot, and the lines 

 are sim"ilar, but in no other species is the linear dark discal spot 

 situated so near the transverse lines, the.se three lines being heavier 

 and most distinct in the middle of the wing. Also the dark brown 

 collar is pecndiar, the thorax not being tufted. The i)ectinated S 

 antenniB will separate the geiuis from any except Notodonta, to which it is nearest allied. 



Professor Smith includes this genus in the Noctuida', placing it in IJombycia, but its venation 

 is that of the Notodontiua', as it has but three branches of the cubital vein, and the subcostal 

 venules are as in the NotodontiuiTe. He also remarks: '-The type is in the Saunders collection at 

 Oxford, England. A figure sent me by Mr. Schaus proves it to be 'Edema frausrerfiata AValk., 

 Ellida (jclida Grt.'" (Cat. Noi-tuid;e, p. 29, 1S'J3.)

Moth. — Head moderately prominent; front squarish, 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 £ well pectinated to the tips; the branches four times as long as
