Forewing. — Male, pale Initf, slightly gray speckled; two dark red 

 costal spots at one-third and two-thirds; from the tirst a curved inner 

 line runs, interrupted above median vein; from the second an irregular 

 outer line, partially lunulate-dentate and projecting squarely between 

 veins 3 and 4; the space between them tilled up with red-brown as far 

 as vein 6, often partiall}^ interrupted along inner edge, the small cell 

 spot lying on the outer edge; this line is paler edged; submarginal 

 line pale, luispeckled; marginal dots deep red; fringe concolorous. 



Hindwing. — Without speckling; a red-brown band from vein 6 to 

 inner margin, wider below" the red-brown cell spot beyond its outer 

 edge; marginal dots large; fringe concolorous, but darker at anal 

 angle. 



Under side ochreous; in the forewing flushed with reddish; cell 

 spots and outer lines black-red; the hair tufts somewhat yellower. 



Vertex, thorax, and abdomen ochreous speckled with red-brown;
