KO.2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. 193 



rounded, similar, in a triangular group, dull olivaceous centered, 

 whitish edged; outer Hne black, slender, dentate, excurved over cell, 

 followed by a broad olivaceous shade to margin, which is obscured by 

 blackish centrally and preceded by whitish at tornus. Hind wing 

 black-brown, fringe paler. Expanse, 26-28 mm. 



Cotypes. — One male, one female, No. 15893, U.S.N.M.; Cabima, 

 May, 1911 (Busck). 



CHALENATA USTATA Druce. 



10. Porto Bello, April, 1912 (Busck); Alhajuelo, April, 1911 

 (Busck); Cabima, May, 1911 (Busck); La Chorrera, May, 1912 

 (Busck); Trinidad River, June, 1912 (Busck); Corozal, Canal Zone, 

 July, 1912 (C. P. Crafts). 



CHALENATA USTATINA, new species. 



Very similar to C. ustata Druce ; smaller, the hind wing clear straw- 

 color with very little brown irroration; marginal area of fore wing 

 with hghter ground, the bands better relieved, not diffused. Expanse, 

 15-16 mm. 



Cotypes. — One male, one female, No. 15894, U.S.N.M.; selected from 

 a series of eight; Paraiso, Canal Zone, April, 1911 (Busck); Porto 

 Bello, April, 1912 (Busck); La Chorrera, May, 1912 (Busck); Corozal, 

 Canal Zone, July, 1912 (J. Zetek). 



Except for the fact that these were taken at the same places and 

 times as ustata, I should consider them small individuals of that spe- 

 cies, so shght are the differences. 



CHALENEATA QUELLA, new species. 



Male antennas pectinate. Fore wing dark gray-brown, nearly 

 unmarked; lines pale, dusky edged, subparallel, wavy, indistinct, the 

 outer tinged with a reddish shade; discal dot minute, black; a row 

 of terminal black dots. Hind wing blackish fuscous with terminal 

 black dots and pale fringe. Expanse, 19 mm. 



Cotypes. — Four males, one female, No. 15897, U.S.N.M.; La Chor- 

 rera, May, 1912 (Busck). 



ORTHOLEUCA ALBILUNA Hampson. 



23. Cabima, May, 1911 (Busck); La Chorrera, May, 1912 (Busck).

Frons with rounded conical prominence; thorax and abdomen 

 without crests; proboscis moderately developed; palpi slender, up- 

 turned, reaching vertex, the second joint fringed with scales below, 

 third smooth. Fore wing with veins 3 and 4 from near angle of cell, 

 5 somewhat above, 7 from apex of cell, 8-10 stalked, 11 oblique, free;
