 fore wings bright chrome yellow. Transverse lines black, distinct. T. a. 

 almost transverse, with slight outward projections below costa, above inner 

 margin and on median vein. T. p. slightly incurved below costa, 

 moderately exserted beyond cell^ thence only slightly oblique to inner

 the middle of the terminal third, following line of outer margin, the second 

 and third from costa subobsolete, the others gradually decreasing in size 

 towards inner margin. Fringe pale yellowish. Hind wings slightly
