particularly between R^ and R^ ; terminal line fine but con- 

 tinuous, blackish, lunulate-dentate, tiie teeth sometimes 

 exjianding into black spots betwen the veins ; fringe con- 

 colorous with wing, slightly dark shaded at vein-ends and 

 divided by a faint fuscous central line. Hind wing with 

 dark marks on inner margin before one-half, representing 

 the beginnings of nearly obsolete double antemedian line ; 

 an ovid pale cell-spot with dark circumscription ; a post- 

 median dark line, sharply angled outwards on the radial 

 fold (R'), thence slightly incurved to near the cell-mark — in 

 one specimen even touching it ; a slight tawny brown shade 

 accompanying the postmedian distally, especially in the (^ ; 

 the pale sul)terminal indicated by w^ak dark shading in the 

 distal area ; terminal line as in fore wing. Underside white, 

 usually with only the same markings as in syrniaria, in the 

 type ( ? ) also with narrow dark shadin2^ continued from the 

 proximal part of the subapical blotch of th^ fore wing as far 

 as M^, a distinct dark cell-spot, and suggestions of a dark 

 submarginal line in hind wing.
