Pamphila coroicana A. G. Weeks, Jr.^ 

 {Plate XVI, Figure 2.) 

 Habitat: Bolivia, near Coroico. Expanse: i.oo inch. 



Upper side of head, palpi, thorax and abdomen, black, with very dark 

 bronzy brown hairs; beneath, lighter, with a slight greenish tinge. Antennae

 black from a line drawn from base along median nervure to end of discoidal 

 space, thence to a point on hind margin one-third distance from lower angle 

 to apex. From a point on costa one-third distance from apex to base, and 

 extending downward to submedian nervure, is a line of interspacial light 

 brownish spots, bending outward toward hind margin opposite discoidal space. 



Under side of hind wing reddish brown. One-eighth inch within hind 

 margin, extending from costa to submedian nervure, and following the con- 

 tour of hind margin, is a line of interspacial light brownish spots, somewhat 

 larger than those on fore wing, but less bright. Inner margin tends to 

 blackish.
