the half-line whitish, rather conspicuous ; the inner and elbowed 

 lines only indicated as limiting the broad blackish central portion 

 of the wing, the inner line somewhat angulate in the middle ; the 

 elbowed line nearly straight from the costa to the elbow, thence 

 continued in a strongly oblique manner to the inner margin, so 

 that the broad central dark portion is nearly twice as broad on 

 the costal as on the inner margin ; beyond the elbowed line the 

 ground colour is much paler, greyish varied with black scales, the
