is rather nearer to the base than on the inner margin ; cilia 

 pale grayish. Hind-wings pale gray, with pale-gray cilia. 

 Thorax dark fuscous, with a purplish hue. Legs and abdo- 

 men beneath yellowish, with a brassy lustre ; the hind tibias 

 fuscous. 



Taken at light on the 1 1th of August. 



& % jjJi- N. bifasciella. Antennae pale fuscous, basal joint silvery. 

 Head pale reddish-yellow. Fore-wings dark bronzy-green, 

 somewhat purplish at the base, with two silvery bands; a 

 rather broad, straight one on the basal third of the wing and 

 a narrower straight one on the apical third ; cilia gray. Hind- 

 wings gray, with gray cilia.

(l'k<}ill$ & Platanella* Antennas dark fuscous, eye-caps large, 

 "silvery. Head reddish-ochreous. Fore-wings dark brown, 

 with a small white, slightly silvery spot on the middle of the 

 inner margin and a very short costal streak of the same hue 

 opposite to it. The cilia very pale yellowish, and the scales 

 behind the cilia of the same hue, tipped with dark brown.

The hind-wings are setaceous. The subcostal is placed 

 nearly in the middle of the wing, is bifid from about the 

 middle, sending a small branch to the costa and a long one 

 along the inner margin to the tip. The median vein is very 

 distinct and simple. 



Fore-wines caudate, when denuded. The discoidal cell is 

 very long and narrow, acute behind. The subcostal vein 

 sends two branches to the costa, a moderately long one from 

 the middle of the cell and one just behind the acute angle of 

 the disk. (In European specimens there are three subcostal 

 branches, two of which are given off near the end of the disk. )
