167. PAMPHILA BYSSUS, Edw. 



Expanse of wings from 1.6 to 1.7 inches. 



Male. Upper surface dark glossy brown ; basal half 

 of costa of fore wings ferruginous, as well as a little of 

 the cell below adjoining ; at the end of the cell an irregu- 

 lar yellow-fulvous bar within ; across the disk a bent 

 yellow-fulvous band, starting on costal margin about 

 three-fifths the distance from base to apex, bending 

 round the cell, and continued to middle of submedian 

 vein, narrow at top, but below the cell widening rap- 

 idly, on the subniedian being in width about one-third 

 the length of this part of the wing. The basal half 

 of hind margin washed with fulvous. 



The hind wings have a fulvous patch in the middle, 

 consisting of a broad band beyond the cell, not reaching 

 either margin, and a small spot in the cell, sometimes 

 the spot obsolete. The hairs of basal area next the 

 inner margin fulvous. Fringes of fore wings dark gray- 

 brown, of hind wings lighter. 



Under side wholly ferruginous (individuals varying 

 a little in shade), except that the posterior half of the 

 fore wings is blackish. The spots of the upper side are 

 repeated indistinctly ; on the hind wings, in most ex- 

 amples, the surface is without spots, in some there is 

 a faint paler color indicating the patch of the upper side. 

 The veins and branches are a shade more yellow than 

 the ground color. 



Body above covered with fulvous hairs ; beneath, the 

 thorax and ventral part of abdomen yellowish, sides of 

 abdomen and legs ferruginous. 



Female. Upper side of same brown as the male, and
