from costa entering cell, suffusing on subcostal with a tliick line 

 from costa across discocellular to veins 3 and 4; a thick inbent 

 line from vein 5 to inner margin; a thick vertical line from costa to 

 vein 5 beyond, with a finer line from its outer edge, outbent and 

 gradually expanding to a large spot at tornus; a large marginal 

 spot, broad below vein 6 and diminishing to near vein 3; marginal 

 black points above and below vein 7 ; termen narrowly more thickly 

 scaled. Plind wing: a fine streak on discocellular; medial clusters 

 of scales at veins 5 to 3, before vein 2, and toward inner margin; 

 a postmedial line from veins 7-5, then downbent to termen at vein 2 ; 

 a marginal spot between veins 6 and 8, and another from below vein 

 6 to vein 4; the termen more thickly scaled; cilia on both wings

 2 to submedian, and a short line below submedian slightly inset; 

 postmedial somewhat lunular, vertical from costa to vein 5, then 

 outset, finer from vein 5 to vein 2; subterminal cross lines on inter- 

 spaces, somewhat inangled from vein 5 to inner margin; a fine ter-
