676 Messrs. W. F. H. Rosenberg and G. Talbot on 
traversed by the dark veins, its proximal edge well defined and 
passing through the centre of the cell, its distal edge powdered with 
the ground-colour. This band extends from vein 7 to the inner 
margin near the base, a faint streak beyond 7. A marginal yellowish 
straight line at 1 mm. from the margin. A white spot at the apex. 
Fringes smoky-brown. 
Underside similar to the upper. Fore-wing with the spots larger 
and silvery white. The costa, apex and distal margin reddish- 
brown. Spot at the apex white, the fourth absent, the fifth white 
and joined to the lower part of the oval spot. The triangular spot 
extends to the costa. 
Hind-wing with the disc silvery white posteriorly darker, edged 
distally with a reddish-brown band 1 mm. wide, bordering the costa 
at the apex and narrowing at the inner margin near the base; the 
band is edged proximally and distally with black, and is widened 
at the base to fill the lower part of the cell. Remainder of the costa 
silvery-white, cellule 7 brownish-black. A silvery-white distal 
marginal border traversed by a thin brownish-black line which is 
obsolete at the apex. Margin narrowly edged with brownish- 
black. Fringes smoky-brown. 
Antennae brownish-black, club bearing a white spot. Upper 
surface of head, thorax and abdomen brownish-black ; palpi brownish- 
black fringed with white hair. Lower surface of thorax and abdo- 
men white, the latter with a mesial brownish-black line. 
Length of fore-wing 25 mm. 
Type, a 3 from El Porvenir, KE. Peru, 900 m., April 
1908. 7 $4 from this locality. 
Eresia letitia nigra, subsp. nov. 
Allied to neptoides but distinguished by the marginal line on 
the hind-wing being crenulate as in letitia. 
Upperside of fore-wing: the spots composing the triangular 
patch beyond the cell are shorter than in neptoides; the three 
apical spots are obscured by the ground-colour, and there is a spot 
in 3 near the margin which is absent in neptoides. The median 
quadrate patch is shorter, the two spots composing it being reduced 
distally. The spot in lc below vein 2 is only marked by a faint 
powdering. Base red-brown. 
Hind-wing with the band narrower and more obscured by the 
ground-colour on its distal edge than in neptoides. ‘The submarginal 
line is bluish-white, thicker than in neptoides, and crenulate as in 
letitia.
