N,o. 2048. :^EW MICROLEPIDOPTERA FROM PANAMA— BUaCK. 5 



Fore wings elongate, ovate, apex round pointed, termen oblique; 

 11 veins: 7 and 8 coincident to costa; 6 to apex; 2, 3, 4, and 5 equi- 

 distant; (7 and 8), 9, 10, and 11 equidistant; 11 from beyond middle 

 of the cell; ll furcate at base. Hind wings somewhat narrower than 

 the forewings with costa gently arched, apex produced, termen 

 strongly sinuate, dorsum straight; 7 veins: 6 obsolete; 7 to apex; 

 2, 3, 4, and 5 well separated, equidistant. Posterior tibiae rough 

 haired above. 



A development from Aristotelia, con-elated with Chrysopora 

 Clemens, from which it diffei-s by the coincident veins 7 and 8 of the 

 forewings. 



BELTHECA PICOLELLA, new species. 



Second joint of labial palpi whitish gray with blackish tuft; third 

 joint black mth a broad, longitudinal, silvery line and with silvery 

 apex. Eyes in the living specimen red. Lower face silvery white; 

 upper face and head dark iridescent brown. Thorax blackish brown. 

 Forewing blacldsh brown with a thin outwardly oblique white streak- 

 let just beyond middle of costa and with two triangular wliite dashes 

 just before apex; a few scattered white scales at the end of the cell 

 and on the fold. Cilia black; just below apex it is short so as to give 

 the wing a slightly emarginate appearance. Hind wings blackish fus- 

 cous with a bluish cast; cilia black. Abdomen iridescent blackish 

 fuscous with sUvery white underside. Legs blackish brown with 

 white tarsal annulations.

Type-specimen.— Csit. No. 16669, U.S.N.M. 



A strildng little species remmding one of the genus Apopira Wal- 

 singham. 



BESCIVA, ne-w genus. 



Type. — Besciva longitudinella, new species. 



Labial palpi long, recurved, sickle-formed; second joint somewhat 

 thickened with scales, smooth; terminal joint longer than second, 

 pointed. Antennse shorter than the forewings. Forewings narrow, 

 elongate ovate with apex pointed; 11 vems: 7 and 8 coincident to 

 costa; 6 separate to termen; 2, 3, 4, and 5 separate, nearly equidistant; 

 11 from beyond middle of cell, subobsolete toward the edge of the 

 wing. Hind wings somewhat narrower than the fore wings with costa 

 and doi-sum nearly straight and parallel; apex produced, termen 

 sinuated below apex; 8 veins: 6 and 7 longstalked; 6 to apex; 3 and 4 

 shortstalked; 5 cubital. Posterior tibiae hairy above. 



Allied to Untomia Busck, from wliich it differs in the separate veins 

 3 and 4 of the fore Aving, the stalked veins 3 and 4 of the hind wing, 

 and in having vein 6 of the hind wdng to apex.
