MEGADREPANA gen. nov. 

 Palpi minute; antennie one-third the length of the costa of 

 the primaries, heavily pectinated for three-fourths of the distance 

 from the base; extremity of the culmen without setae; costa of 

 primaries strongly arcuate before apex; apex strongly falcate, 

 inner angle obtuse. Secondaries subtriangular with the outer 

 margin evenly rounded, abdomen not projecting beyond the 

 outer margin of the secondaries. The lower radial nervule of 

 the primaries has its origin at the middle of the cell, where the 

 disco-cellulars form an acute angle with its vertex toward the 

 base. The upper radial has its origin before the end of the cell 

 and forms, with the disco-cellular, the upper angle of the cell. 

 In the secondaries the lower radial rises at the middle of the end 

 of the cell, and the upper radial at its upper angle, the subcostal 

 in the secondaries arising before the end of the cell. Type M. 

 cinerea Holl. 



17. M. cinerea, sp. nov. cf. — Antennae testaceous; front and collar pale 

 gray; thorax and abdomen dark gray. 



Upperside: primaries and secondaries are obscure ashen-gray with 

 some rusty markings near the apex of the primaries, and an obscure 

 transverse median and limbal line upon both wings. The outer margins 

 of the secondaries are broadly darker than the body of the wing. 



Underside: both wings are cinereous, with the costa of the primaries 

 before the apex marked with ferruginous. The lines of the upper surface 

 reappear upon the lowerside, but more distinctly, and in the secondaries 

 the limbal line is diffuse, accentuated with bright ferruginous ocelli, which 

 are more or less obscurely defined. Expanse 60 mm. 



600DIA gen. nov. 

 %. — Palpi minute, compressed, last joint extremely minute; 

 antennae broadly pectinated for three-fourths of the distance 

 from the base, end of culmen naked; body heavily clothed with 

 hair; legs short, hairy. Primaries strongly arcuate before the 

 apex, falcate; outer margin strongly concave; outer angle 

 rounded. Secondaries substriangular with the outer angle 

 rounded, the outer margin strongly convex, the anal angle more 

 or less produced, the inner margin straight. In the primaries, 

 the lower radial arises from the middle of the cell, the upper 

 radial from the upper angle. The disco-cellulars do not form an 

 angle with each other at the end of the cell. In the secondaries, 

 the disco-cellulars form an angle below the origin of the lower 

 radial, and the subcostal has its origin very slightly in advance
