WEEKS — SOME NEW BUTTERFLIES 105 
Upper side of fore wing dead blackish brown. The basal area below median 
nervure is in some lights bright lustrous blue. Hind marginal fringe at apex, 
of ground color. Hind marginal area at the apex, of ground color, but shading 
to tawny at lower angle. In discoidal space, near its end and touching sub- 
costal nervure, is a small white dot. Below this, in discoidal space and slightly 
nearer base, is another somewhat larger dot resting on median nervure. In the 
interspace above the lowest submedian nervule, about one quarter inch from 
hind margin, is a semi-transparent white spot crossing the interspace, concave 
on its outer side. In interspace above this, slightly nearer hind margin, is 
another similar spot, somewhat smaller. 
The upper side of hind wing is of same ground color as fore wing. The 
basal area in some lights is bright lustrous blue. The hind marginal fringe is 
bright tawny, thread-like at upper angle but broadening to one eighth inch 
wide at anal angle. This prominent fringe and the lustrous blue of basal areas 
form the prominent markings of upper surface. 
The under side of fore wing is dark brown. The spots of upper surface are 
distinctly repeated. From costa, one third distance from apex to base, extends 
a soft suffusing band of grayish, running toward centre of hind margin and 
then turning at base of apical area and paralleling hind margin, disappearing 
toward lowest submedian nervule. The immediate apical area is of same color, 
suffusing gently toward this band. Inner marginal area light brown. Hind 
marginal fringe the same as on upper side. 
Under side of hind wing same ground color as fore wing. Costal area, near 
base, grayish. From centre of costa, extending toward base, is a soft suffusing 
band of grayish. From apex, running across to inner margin, is a similar 
band, broken and made irregular by suffusions of the ground color. Running 
from apex toward anal angle, in hind marginal area, is another band or space 
of similar coloring, ending at lowest submedian nervule, concaved in interspaces 
just within hind margin, and somewhat broken along its central portion by the 
ground color. Hind marginal fringe bright tawny, as on upper side, but suffus- 
ing more toward the base at anal angle. 
Taken near Cusilluni in May, 1899. 
Telegonus tritonz sp. nov. 
Habitat: Bolivia, near Chulumani. Expanse: 2.50 inches, 
Head, thorax, abdomen and legs, dark brown. Eyes encircled by a white 
thread. Antennae dark brown, tipped with light brown on under side. 
Upper side of fore wing dark brown without lustre. From centre of costa, 
running toward inner angle and stopping at lower submedian nervure, is a band 
of pure silvery white, one quarter inch wide. A portion of this extends down-
