DESCRIPTIONS OF SIX NEW BUTTERFLIES FROM 
BOLIVIA. 
BY A. G-WEEKS, JR: 
Ceratinia acceptabilis sp. nov. 
Habitat : Coroico, Bolivia. Expanse: 2.45 inches. 
Head black with a white dot behind each eye. The eyes are encircled by a 
fine white thread. Antennae black with bright yellow club. Thorax, above, 
black ; beneath, black with two transverse yellow lines. Abdomen, above, 
black ; beneath, light yellow. Legs black. 
Fore wing, above, nearly all transparent with a blackish tinge. The trans- 
parent portion shows a mother-of-pearl lustre in some lights, as do all species 
of this genus. The costa and hind margin are bordered with black for one 
sixteenth inch, somewhat broader at apex. The inner marginal area, up to 
lower submedian nervule, is entirely black. The outer portion of discoidal 
space and the portion of interspaces adjoining it, down to lower submedian 
nervule, are transparent, but tinged with yellow instead of with black as 
the balance of the transparent portion is, giving the appearance of a broad yel- 
low band crossing the wing. This band is starcely perceptible on direct exam- 
ination, but by turning the insect at an angle, it shows prominently. The 
nervures and nervules are black. The black of the nervule crossing the end 
of discoidal space suffuses slightly at its central portion, causing it to appear 
as a prominent feature of the wing. Along the inner edge of the black hind 
marginal border is a series of very prominent interspacial white spots, running 
from costa, close to apex, down to the lower submedian nervule. 
Upper side of hind wing has a broad hind marginal border of black one 
quarter inch wide. This extends from upper angle area to the lower sub- 
median nervule, and then dwindles abruptly to a point at anal angle. In its
