beginning with a quite well-marked apical patch of the same colour, quite 



irregular, projecting inwardly opposite cell and again in lower third, 



traces of black dashes preceding it in some specimens. Orbicular small, 



round, black outlined, complete or open above, concolorous with costa, 



usually darkened centrally. Reniform about normal shape and size, pale 



creamy yellow, luteous centred, outlined in black. Claviform solid black, 



moderate in size. Black terminal line, emphasized between veins into 



lunules, which show a tendency in some specimens to extend across the 



terminal space. Fringe luteous at base, darker centrally, whitish at edge. 



Secondaries subpellucid, white, slightly dusky at apex and along veins. 



Fringe white, dusky line at base. In V > smoky with faint discal dot. 



Beneath fore wings more or less smoky, paler along inner margin. Discal 



dpt, though not prominent. Mesial band distinct on costa, fading out 



before inner margin. Pale area at apex preceded by dark patch at 



inception of outer shade. Hind wings whitish, some dark scales along 



costa, small discal dot. Mesial band evident on costa and continued by 



a (tw dusky dots a short distance across wing. In ? > the wings beneath 



are darker and the bands more prominent. Head, collar, thorax and 



abdomen concolorous with ground colour. Collar with mesial black

 edge. Distinct black basal dash to t. a. line. A black dash from before 

 orbicular through cell to t. p. line. Basal line obsolete. T. a. line 

 double, obsolete above, scalloped between veins below median, outer

 evident beyond cell, but not prominent, pale, confining lines scarcely 

 discernible. The remainder of line to inner margin scarcely traceable, 

 except in certain lights. S. t. line not evident. A triangular portion of 

 subterminal space below costa somewhat darker than ground colour. The 

 termmal space, especially opposite cell, is also more or less irregularly
