58 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. 



w-ing is oblique and rather sharply drawn from apical fourth of costal 

 to shortly after the middle of dorsum; costal edge from apical third 

 to apex dark greenish brown, unmottled; cilia light violaceous fus- 

 cous, with strong, iridescent, metallic luster. Hindwings dark olive 

 brown, with light violaceous, iridescent cilia. Abdomen dark olive 

 brown; underside of body silvery brown. Legs light violaceous 

 brown, barred with dark brown; first tareal joints with large white 

 spots above. 



Alar expanse. — 14-15 mm. 



Habitat. — Cabima and Porto Bello, Panama, March and June. 



Type-specimen.— Ca,t. No. 16759, U.S.N.M. 



This species is close to T. Julgens Feldcr and Kogenhofer, but 

 differs in the two-colored thorax, the black basal streaks, the absence 

 of metallic purple on basal thhd of the wing and the much lighter 

 silvery fasciae. 



TORTYRA FERRATELLA, new species. 



Labial palpi whitish gray. Face iridescent, bluish silvery. Head 

 deep metallic green. Antennae with thickened basal two-thirds deep 

 metallic blue; a broad white annulation at apical third; tip dark 

 brown. Thorax light silvery fuscous with two, broad, dark blue, lateral 

 streaks. Forewings with the dark brown ground color irroratcd and 

 obscured by closely set whitish ochi-eous stippling, which forms fine 

 transverse lines; just before the middle of the wing is a broad fascia 

 of light steel colored scales, not very different from the stippling on 

 both sides except in their luster; the fascia is markedly broader on 

 the dorsal side than on the costal side and is edged wdth two, broad, 

 blackish brown, transverse lines of which the outer is the broadest and 

 nearly straight, v/hile the basal one is irregularly undulating and as a 

 whole slightly convex; across the base of the wing runs an oblique, 

 interrupted, dark brown streak, and extreme base of costal edge is 

 black; terminal part of the wing dark metallic blue, irrorated with 

 gold and with a broad, golden, longitudmal streak at tornus; in the 

 outer part of the whitish stippled part of the wing run several, spread- 

 ing, longitudinal, deep black lines, mainly along the veins; apical 

 fourth of costa dark umnottled brown; cilia dark brown with strong 

 ferruginous sheen. Hindwing dark purplish brown with light steel 

 colored cilia. Abdomen dark silvery fuscous. Underside of entire 

 body silvery white. Legs silvery white with blackish brown bars and 

 last tarsal jomts blackish brown. 



Alar expanse. — 15 mm. 



Habitat. — Paraiso, Panama, January. 



Type-specimen.—C&t. No. 16760, U.S.N.M. 



Belongs to the group of auriferalis Walker and spectahilis Walker, 

 but differs from both by the black longitudinal striation, as well as 

 by the more subdued coloration, especially of the fasciae.
