The geuus differs from Notodoiita in the more stroiiji'ly pectinated aiitenniv, in the more 

 pointed, less rounded wings, and iu the venation. The palpi axe nearly the same.

Moih. — Two S . Head, palpi, and prothoracic collar vandykebrown. the front part of the 

 thorax contrasting with the mouse-gray hinder portion. Fore wings uniform asli-gray; no 

 distinct 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 most distinct and heavy between 

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

 extend to the inner edge of the wing, but the middle one is obsolete. The outermost of the three' 

 lines is situated very near the dark A'andyke brown, distinct, curvi- 

 linear discal spot, and this distinguishes the species from any other 

 Xotodontian. On the outer fourth of the wing are two faint scal- 

 loped dark lines, represented by venular dots; a marginal row of 

 irregidar brown spots. 



Hind wings and abdomen dark ash-gray, autl 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, $ 37-4:! mm.; length of body, i l'> mm. 



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

 leptinoiih's^ as the shape of the wing, the discal spot, and the lines 

 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 iu the middle of the wing. Also the dark brown 

 collar is peculiar, the thorax not being tufted. The i)ectinated $ 

 antennie will separate the genus from any except Notodonta, to which it is nearest allied. 



Profes.sor Smith includes this genus iu the Noctui(he, placing it in Boinbycia, but its venation 

 is that of the Xotodontime, as it has but three branches of the cubital vein, and the subco.stal 

 venules are as in the IS^otodontinjie. He also remarks: ''The type is in the Saunders collection at 

 Oxford, England, A figure sent lue by Mr. Schaus proves it to be ^ Edema transversata Walk., 

 EUida (jelida Grt."" (Oat. Noctuid;^, p. 20, 1S93.)
