4 WEEKS SIX BOLIVIAN BUTTERFLIES [^iflli ' 



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 vV~. iceius Scudd., 

 and N. brizo Bsd.-Lec.
