The violet patch contains from five to six divisions : in the type 

 in Mr. Druce's collection there are five, the two upper ones being 

 very minute, and all of them being distinctly separated ; one example 

 of the three males presented by Mr. Buxton has six divisions, sepa- 

 rated only by the black nervures. 



3f. Violet apical patch of the male bordered on both sides with 

 black ; internal vein and apical two thirds of remaining veins 

 beyond cell of primaries black ; basal area and internal two 

 fifths of secondaries dusted with grey ; internal area of primaries 

 tinted with sulphur yellow ; secondaries with black veins, ter- 

 minating in black marginal spots : below, the apex of primaries 

 and the secondaries tinted with pink, the latter with an oblique 

 dotted line (composed of four to five small brown spots) ; base 

 of costa ochraceous. Female with the apical patch orange, 

 bordered with black and crossed by black spots, or black crossed 

 by five white spots : secondaries below pinkish grey or yel- 

 lowish, reticulated with pale brown, crossed by an oblique brown 

 streak, and with brown outer borders ; base of costa sometimes 

 ochreous.
