 their tips to black-brown ; basal line when perceptible 

 deep black, broken into two or three dots which have 

 paler margins; first line jet black, deeply and sharply 

 angulated ; second line placed only just beyond the middle 

 of the wing, deep black, much curved and formed into a 

 series of crescents with long points which run along 

 nervures and render them more deeply black ; subterminal 

 line hardly perceptible, but indicated by a row of small
