brown ; discal spot of fore wing smaller, of hind wing scarcely 

 indicated. 



Huancabamba, Cerro del Pasco, E. Peru (type) ; also a S 

 in Coll. Br. Mus., from Rio Janeiro, lab ailed psittacina by 

 Warren (ined.). 



Extremely close to R. lafayaria, Dogn. Le Nat. 1892, 

 p. 206, but differing in shade of colour, bright yellow 

 margins of blotches, and some other details, which satisfy 

 M. Dognin that it is a separate species. 



Xenopepla (Warr., indescr.), gen. nov. 



Face smooth. Palpus ( $ ) moderate, porrect, rather long- 

 scaled; third joint small, concealed. Antenna (3) bipecti- 

 nate with long branches (apices broken). Pectus and 

 fore femur somewhat hairy ; hind tibia ( $ ) dilated with 

 hair-pencil, all spurs well developed, tibial epiphysis prolonged 

 into a process about one-third the length of tarsus, which is 

 not abbreviated. Abdomen not crested. Fore wing rather 

 elongate, costa gently arched, apex moderate, termen entire, 

 nearly straight in anterior half, then suddenly oblique, hence 

 appearing gibbous at R 3 and M 1 , though not angled; cell 

 fully one-half, DC incurved, SC 1 (in the type species) anasto- 

 mosing shortly with C, SC 2 ' 5,3 ' 4 stalked, connate with R 1 ; 

 R 2 from above middle, M 1 connate with R 3 . Hind wing 

 without costal dilatation at base, frenulum developed ; apex 

 rounded, termen deeply sinuate from R 1 to R 3 and more 

 weakly from M 1 to tornus, toothed at R 3 , tornus well pro- 

 nounced ; cell one-half, DC slightly curved ; C anastomosing 

 with SC at a point near base, then rapidly diverging, SC 2 

 stalked with R 1 , R 3 considerably above middle, M 1 stalked 

 with R 3 . 



Type of the genus : Xenopepla bicuneata, sp. n. 



Xenopepla bicuneata, sp. n. 



<$ . 23 mm. — Head, body, and legs uniform dark fuscous. 

 Wings dark fuscous, with an indistinct paler line (not 

 yellowish, as in flavinigra, Warr.) near to and parallel with 

 distal margins. Fore wing in addition with two rather large, 

 broadly wedge-shaped, yellow markings midway between cell 

 and termen, separated by R 2 , their narrower ends pointing 

 basad. Hind wing with a yellow central blotch from costa 

 to R 3 , enclosing, near its proximal margin, the thick elongate 

 fuscous cell-spot ; a small yellow spot between this blotch
