smaller dorsal light yellow dash; at the end of tlie cell is a short, 

 bluish metallic transverse streak broadly edged with black and above 

 it is a short, bluish metallic costal streak; beyond the end of the cell 

 is an oval black patch traversed by fine, longitudinal, white lines 

 and dashes ; two light yellow costal dashes just before and in the cilia, 

 preceded by small metallic spots; a broad, curved, interrupted, bluish 

 metallic band around the termen edged on both sides with black;

Alar expanse. — 10 mm. 



Habitat. — Porto Bello, Panama, April. 



Type-specimen.— Ciit. No. 16762, U.S.N .M. 



Very similar to the type of the genus in color and pattern, but 

 smaller and differing in details, by the black, white-striped, oval patch 

 beyond the cell and by the two basal yellow streaks being separate. 



USSARA EUMITRELLA, new species. 



Labial palpi with terminal joint even more flattened than in the 

 other species of the genus; black, with two thin, longitudinal, yellow 

 stripes. Face and head black. Thorax black with a small yellow 

 dot at posterior tip. Forewings black on basal part and on a large 

 round area within tornus; elsewhere dark golden ochreous; the 

 black basal part covers about a third of the wing and contains at 

 basal fourth a large, light yellow, pointed, dorsal streak which reaches 

 beyond the middle of the wing; the reddish ochreous part of the 

 wing contains six small, bluish metallic, black edged, costal streaks, 

 one terminal metallic streak below apex and two larger, dorsal, 

 metallic streaks between and edging the two black fields; at the end 

 of the cell is a bluish metallic round spot; cilia blackish brown. 

 Hindwing blackish brown. Abdomen blackish brown with broad, 

 transverse, silvery white bands on the underside. Legs black with 

 narrow white annulations at the joints and with the outer spurs 

 white.

Type-specimen.— Cut. No. 16763, U.S.N.M. 



Very close to Z7. repletana Walker, but differing in the large basal 

 black patch and the unmottled black tornal patch, as well as in the 

 coloration and size of terminal joint of the palpi.
