This form differs from iS. violasce.ns in not being violaceous al)ove, though 

 slightly so beneath; the two lines are much more distinct and not edged with 

 paler tints, and the hind wings above are not lineated nn'sially. It may also 

 be recognized by the hind w ings beneath having the outer line straight, while; 

 the pectinations of the antennas are black. The two species are readily dis- 

 tinguished by the inner line in the present species being straight, while in 

 kentarla it is bent at nearly right angles, and in the latter the hind wings 

 are distinctly serrate.
