 an antemedial outwardly white line, inwardly edged by a large hyaline 

 spot, its lower edge curved; vein 3 v,'ith a whitish line. The post- 

 medial white line vertical and wavy followed by a slight reddish line 

 and a broader pale brownish-drab shade with whitish irrorations; this

 outer edge, enclosing a dark lavender spot on each interspace; from 

 vein 7 to inner margin a subterminal pale brownish drab irregular 

 fascia edged by a fine, irregular, black line; terminal space on apex 

 brownish drab, with some fuscous streaks beyond the postmedial white 

 line, a fine white line from apex inbent to vein 7, beyond on vein 7 a 

 cluster of black spots; termen whitish tipped with avellaneous. Hind

 white from costa to inner margin at one third from base enclosing a 

 black streak and reddish scaling; inner margin to postmedial line
