WEEKS — THREE NEW BUTTERFLIES eS 
dashes are prominent black spots in some specimens. The apical space out- 
side this series of yellow marks, and covering one third of the wing, is black, 
with three transverse, light yellow marks, the upper one being a small subcostal 
dash, the lower two being prominent, interspacial, elongated spots. Outside 
of these, some specimens show signs of interspacial white spots just within 
the hind margin. The submedian nervure is distinctly black, suffusing con- 
siderably, in some specimens, upon the surrounding ground color (dark tawny), 
and broadening into a large spot at anal angle. The hind margin is, as above 
described, black, with a white thread showing at interspaces. 
Upper side of hind wings dark tawny. Costal space and hind margin bor- 
dered with black, one quarter inch deep. Running from upper angle trans- 
versely across to centre of inner margin, is a series of interspacial black dashes, 
forming a prominent black band across the centre of the wing. At upper 
angle there is a prominent light yellowish spot. Hind margin edged with an 
interspacial white thread. 
Under side of fore wings the same as upper surface, except that the light 
yellow markings are more pronounced and suffused and the black showing 
within them and at their edges is, consequently, more prominent. The black 
of apical area is dark tawny brown in some specimens. The three subapical 
white spots are much larger. The inner marginal area tends to blackish gray. 
The under side of lower wings has the same markings as above, with a few 
variations. The subcostal area is black. In the place of one apical white 
spot, there are two, interspacial. Under the costal nervure, is an anvil-shaped, 
light yellow spot. Below this the ground color is dark tawny brown, the 
transverse band of interspacial black dashes being well defined. The hind 
margin is edged with a white thread, and within this each interspace contains 
two white dashes, near the margin. 
The ground color of the under side is variable (dark tawny to blackish), and 
the suffusion more or less pronounced. The general markings, however, main- 
tain their proper limits, although the suffusions may alter the general appear- 
ance of the wing. 
Described from specimens taken in May, 1899, in Bolivia, and
