4 WEEKS — SIX BOLIVIAN BUTTERFLIES Beart Til 
vous wavy lines. This space is narrowest opposite discoidal space, broadening 
out toward costa and inner margin. Inside of this, and extending from costa 
through outer point of discoidal space, is a space of light fulvous, three eighths 
of an inch wide, jaggedly bordered by a darker line and dusted somewhat on 
inner side with silver scales. The discoidal space is crossed by a silver line 
about a quarter inch wide at costa and narrowing somewhat toward inner mar- 
gin which it meets at right angles. This line, extending as it does across the 
hind wing, is the prominent feature of the lower side. In the centre of this 
silver band, beginning at the costa, is a black jagged thread, leaving it at the 
centre of the discoidal space and extending to the median nervule. The area 
on basal side of this silver band is dark fulvous with one black thread running 
down from costa, and, when midway, turning toward the silver band. The 
lower interspaces are suffused with black toward the base. The outer portion 
of discoidal space contains two oblong black-edged figures and another below 
them, circular in shape and lighter in color. 
The hind wing has no defined border, the entire outer half being of light 
fulvous transversely crossed with a mass of wavy blackish lines. Under the 
costa, midway from base to apex, is a fulvous ocellus, one quarter inch across, 
bordered by a black thread and inclosing a half moon of minute white specks. 
There is another similar ocellus just below discoidal space, having, however, 
a yellow line within the outer black thread, and a heavy dusting of dark blue 
scales at lower edge. The silver band of fore wing extends across the dis- 
coidal space, terminating at the third median nervule. The outer portion of 
discoidal space is crossed by several irregular black threads. The space with- 
in the silver band is identical with the outer portion of the wing. 
This superb specimen was taken September 12, 1899, by my 
collector, Mr. William J. Gerhard, and I take pleasure in naming 
it after him. It differs from others of this genus in that the lower 
ocellus of hind wing beneath is single, and the general coloring of 
under surface is quite different. 
Nisoniades menuda sp. nov. 
Habitat: Bolivia. | Expanse: .75 inch. 
Head, thorax, abdomen, antennae and legs, above, very dark brown, nearly 
black; beneath, the same, except that the antennae are lighter. 
Upper surface in general appearance closely resembles 4. zce¢us Scudd., 
and JW. érizo Bsd.-Lec.
