olute edge yellowish, including the brush of hairs. Beneath, much as above, 

 bul paler, the wing beyond the middle being crossed by a broad reddish 

 shade, and yellowish on each side, including the apex. Hind wings with two 

 parallel yellowish lines.

Callcdapteryx Grote, Trans. Aincr. Ent. Soc, ii, 119, 1838. 



$ and 9. — Head much as in Acidalia, being short, small, and the front 

 rather wide, subtriangular. Male antennae simple, very slightly flattened. 

 Palpi slender, slightly upcurved, pointed, projecting a little beyond the front. 

 Fore wings with the costa very much arched, the apex being very falcate; 

 below the apex, the outer edge is deeply and regularly excavated, with a sub- 

 acute angle between the first and second median venules; the inner angle is 

 sharply rectangular, and the inner edge is deeply sinuate. The hind wing is 

 oblong; below the apex, produced into a long, very acute point, below which 

 the wing is deeply hollowed, with a small acute tooth near the middle of the 

 hollow; a broad acute angle on the first median venule ; inner angle rectangu- 

 lar. Venation: six subcostal branches, the independent forming a seventh, 

 as it co-originates with the origin of the anterior discal venule. The first 

 three subcostal venules originate near together, and some distance before the 

 origin of the anterior discal venule. .The remaining venules are very straight, 

 not arched as in Callizzia. The internal vein is very sinuate. Abdomen 

 short and thick. Hind legs stout ; tibiae swollen, with large unequal spines; 

 tarsi two-thirds as long as the tibiae. The single species known is dull ochre- 

 ous, with two nearly parallel lines, and dark patches on the hollows of the 

 outer and inner edges. 



This singular genus may be at once recognized by the deeply-hollowed 

 falcate fore wings, with the deeply sinuate inner edge, and by the deeply- 

 notched, tridentate, outer edge of the hind wings.
