Melinaea orestes clara, forma nov. 
This form of orestes, Salv., is easily distinguished by the absence 
of any marking on the hind-wing except a spot at the inner margin 
near the base. Differs also from orestes in that the black inner 
margin of the fore-wing reaches the distal margin, so that the 
prong of the yellow fork at the outer angle is equal to or narrower 
than the prong above it. Typical orestes was described from Pozuzo. 
On the underside of the fore-wing, the grey streak on the inner 
margin is extended to the first submedian and reaches the distal 
margin in a curve. 
On the underside of the hind-wing a black subcostal band extends 
from the base to near the apex, bordered by the costal vein and 
filling the upper part of the cell. Length of fore-wing 58 mm. 
Type, a § from Yahuarmayo, 8.H. Peru, 1200 feet, April 
and May 1912. A series of males from this locality 
(October and November 1910), where it is found in company 
with typical orestes. 
Melinaea orestes is synonymous with chincha, and has 
nothing to do with flavosignata as described in Seitz, 
‘“‘ Macrolepidoptera of the World,” vol. 1, p. 122.* 
Napeogenes semingra, sp. nov. 
Nearest to rowena, Hew., but the yellow band is absent and also 
the two spots at the end of the cell. The black band on the hind- 
wing is also characteristic. 
6 upperside. Fore-wing brown, outer half black extending to 
vein 2 and filling the cell at the apex. A black wedge-shaped spot 
in the cell and a small similar spot in the angle at the base of 2. 
Costa black, wider near the base. A broad black stripe at the 
inner margin. Hind-wing brown, costal and outer margin black 
and proximally dentate. A central black band extending far 
beyond 5 to the inner margin. 
Underside similar to the upper. Fore-wing with a marginal 
row of 6 white dots. Hind-wing with 2 white dots at the apex; 
a yellow streak at the base. 
2 similar to the g. Inner marginal streak of the fore-wing 
narrower, as also the black band of the hind-wing. 
Head and thorax black, collar and patagia brown. Abdomen 
* Although this is here treated as a form, it is not unlikely that 
examination of the genitalia may show it to be a separate species. 
We have received about equal numbers of clara and typical orestes 
from the same locality, and have not seen yet any intermediates.
