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. 



Lycaena babhru A. G. Weeks, Jr.^ 

 {Plate XLIII, Figure i.) 

 Habitat : Sicasica, BoUvia. Expanse : .88 inch. 



Head, abdomen and legs, light brown above ; whitish beneath. Thorax light 

 brown above; white beneath. Palpi light brown, almost white, tipped with 

 black. 



General ground color of upper surface is brown, with considerable lustre. The 

 hairy fringe of hind margin is brown, shading to white at outer edge. There is 

 a black thread along hind margins. 



The upper side of fore wing is light brown without markings, the density of 

 the brown being variable in various lights. 



The upper side of hind wing is the same, except that there are interspacial 

 lunules of white near hind margin, scarcely perceptible at apex, but growing 

 quite prominent near anal angle. These lunules are nearly circular, the enclosed 

 space being somewhat darker than the ground color, resembling darkish spots. 



The under side of fore wing is light brown, without lustre. Hind marginal 

 fringe the same. From the subcostal interspace downward is a line of inter- 

 spacial dark spots surrounded by a whitish thread, seven in number, the upper 

 four near centre of wing and in line with the hind margin, the lower three 

 somewhat nearer base. Inside the upper four spots, nearer base, and in the dis- 

 coidal area, are two more similar spots less distinct. In interspaces at hind mar- 

 gin, is a series of lightish lunules surrounded by dark brown, all quite indistinct. 



The under side of hind wing is of the same ground color; the marginal fringe 

 also. In subcostal area, midway from apex to base, is a dark spot, with a whitish 

 border resembling the spots on fore wing, and near the base is another. Below 

 the median vein at end of discoidal space is a prominent dash of white extend- 

 ing nearly to hind margin. This forms the prominent mark of under surface. 

 From its basal end, and running to inner margin, is a series of three white 

 lunules. The lunules at hind margin are far less distinct than on upper surface, 

 and are elongated toward the base. 



Taken in October, 1899.
