ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 53 



Pamphila errator A. G. Weeks, Jr.^ 

 {Plate XV, Figure i.) 



Habitat: Bolivia, Coroico district. Expanse: i. 00 inch. 



Head, palpi, thorax, abdomen and legs, bronzy brown above; grayish brown 

 below. 



Upper side of both wings bronzy brown, with some lustre. Hind margins 

 slightly fringed with hairs of a lighter shade. There are no markings except 

 on fore wing, where there is a line of almost imperceptible interspacial 

 whitish spots, running from subcostal interspaces down to inner margin, start- 

 ing at costal interspace about one-third distance from apex to base, those at 

 centre of wing being nearer the hind margin than the others. 



Under side of fore wing grayish brown, tending to blackish toward base 

 and inner marginal area. Hind margin has a blackish thread within the 

 fringe. The lightish spots of upper surface are black, with whitish suffusion 

 outward. This row of spots is the prominent feature of the under surface. 



Under side of hind wing grayish brown, tending to blackish toward inner 

 margin, but not tending to blackish at basal area, as is the case in fore wing. 

 The black spots of fore wing continue across the secondaries, following the 

 contour of the hind margin. The spot beyond the end of discoidal space, 

 however, is double the size of the others. 



Taken near Coroico, April 20, 1899. 



Pamphila argentea A. G. Weeks, Jr.'^ 

 {Plate XV, Figure 2.) 



Habitat: Bolivia, Cusilluni district. Expanse: 1.20 inches. ' 



Head, thorax, antennae, abdomen and legs, bronzy brown above; more 

 grayish beneath. 



Upper side of fore wing bronzy brown. In subcostal interspaces, at apical 

 area, are two whitish dots. Just above the second subcostal nervule is a 

 larger dot, and in interspace below, somewhat nearer base, is another still 

 larger one, with its upper part nearer the hind margin than the lower part. 

 In interspace below is another longitudinal spot of nearly similar size, resting 

 on submedian nervure.
