 the marginal space brown ; a small brown spot at inner angle, with 

 two or three black spots above it in sub-median sulcus, with faint

 medio-superior interspaces. Posterior wings rose-color in the 

 middle, with a brownish patch at the tip crossed by two or three 

 short whitish lines ; ocellus black, pupil pale blue, with two short
