is a slight vertical tuft, and the front is much smaller and broader, and 

 , the sides are more excavated than in the preceding genus. Palpi 

 small, weak, not reaching the front. Antennjie well pectinated, the 

 branches being well developed in the female. Body more slender than 

 usual. The fore wings in their general form closely resemble Platyp- 

 teryx but are not so much produced towards the apex, which is broadly 

 triangular. The outer margin is three-toothed, being deeply incised ; 

 the middle tooth is the largest of the three. In the secondaries the 

 apex is much rounded ; the outer margin angulated in the middle ; and 

 the inner angle which passes beyond the tip of the abdomen by a dis- 

 tance equal to a fourth of the length of the inner margin of the wing, 

 is not so angular as is Platypteryx. The interspaces of the fore wings 

 are narrower on the costal region and broader below than in the former 

 genus ; while the median interspaces are shorter. The median nervure 

 is less curved where it throws off its nervules, than in the typical genus. 

 Legs much as in Platypteryx. 



In its style of coloration the species may be known by the two oblique 

 straight parallel lines crossing the fore wings, which are strigated 

 transversely as in some Greometridre, such as Choerodes and allies. 



This fragile and very slender bodied genus can at once be distin- 

 guished from Platypteryx by the deep serrations of the outer edge of 

 the fore wings. It also differs in the broader front of the head, smaller 

 palpi and shorter pectinations of the antenna?. 



I have seen but one female specimen from which to make this de- 

 scription. 



Edapteryx bilineata n. sp. 



9 . A delicate thinly scaled species of an ochreous silvery color ; the 

 ochreous scales appearing along the outer border, and lining the trans- 

 verse lines. These two lines are in the middle of the wing, the outer 

 being a little flexuousj both are dark, the inner one lined within and 

 the outer one lined externally with ochreous. A distinct black discal 

 spot. The fore wing is thickly covered with long transverse brown 

 strig* or short lines which become near the outer edge oblique and 

 sinuate, forming an obscure submarginal line. 



Secondaries paler and dusky perlaceous. Discal dot distinct and 

 beyond is a transverse dark line once angulated opposite this spot. Be- 

 yond this line the wing is obscurely strigated.
