6 WEEKS — SIX BOLIVIAN BUTTERFLIES [ P Voi. ill 



the adjoining portion of the four lower interspaces, are dark brown, excepting 

 a slight white dash in discoidal space, extending from outer end and running 

 toward base. There is another smaller dash above it, and also a very promi- 

 nent triangular white mark, one quarter inch long, with its base at end of dis- 

 coidal space, extending toward hind margin. The entire brownish area is light- 

 ened by a scattering of grayish scales, thickest near base. 



Hind margin of hind wing dentated, and edged by a white thread. The bor- 

 der of hind margin is nearly black, and just within the edge is a series of inter- 

 spacial half moons of blue. The basal area is brown. The rest of the wing is 

 white, excepting a band of brown running transversely across centre of wing. 



Under side of fore wing has same markings as upper side, but the brown is 

 replaced by orange. There is also an irregular white line running from base to 

 end of discoidal space. 



Under side of hind wing is the same as upper side, except that the brown is 

 replaced by dark orange dusted with blackish scales, and the white portion, 

 while fully as prominent, is more restricted in its area. The half moons at 

 hind margin are white instead of blue. 



In some specimens the brown portions are so heavily dusted with white 

 scales that they appear gray, while in others there is almost an entire absence 

 of this dusting. The orange apex of fore wing contains in some specimens 

 one or two white interspacial dashes. 



Described from twenty-three specimens taken on the mountains 

 near Coroico in May, 1899.

 nervure, is a still larger similar mark crossing entire interspace, concave on 

 both sides. In the interspace above this and nearly touching these two large
