HYSTEICHOPHORA.* 



Caput hirsute vestitum. Palpi ultra apices hirsute vestiti, capite quasi ter longiores, 

 articulo medio triangulari, apicali brevissimo. Antennae maris subpubescentes. Alee anticce 

 parum ornatce, costa arcuatd ( J" revolucro nullo), apice depresso pcene falcato, margine apicali 

 suboblique concave, dorsali convexo ; venis duodecim singulis. Alee postica vend media prope 

 quartam ortd, margine postico sub apice vix impresso. 



Head thickly clothed with long hair-like scales, projecting forward between the antennae: 

 palpi also roughly clothed with long hair-like scales, which extend considerably beyond the 

 end of the short apical joint, projecting twice the length of the head beyond it; the second 

 joint thickened in the middle above, almost triangular ; the apical joint very short, obtuse. 

 Fore wings with the costa evenly arched, the apex produced and depressed, but scarcely 

 falcate ; the apical margin slightly oblique, concave ; dorsal margin rounded ; the male 

 without a costal fold ; veins 12, all separate at their origin. Hind wings with the outer 

 margin slightly indented below the apex, rather wide, with long cilia ; the median vein with 

 long hairs above at the base ; vein 5 arising near the same point as 4. The inner spur of 

 hind tarsi considerably longer than the outer.
