 branches, first emitted at one-third before end of the cell ; discocellulars 

 very oblique ; radial from near their middle ; two upper medians from end 

 of the cell, lower at one-third before the end ; median straight ; internal 

 short. Body moderate ; palpi ascending, second joint long, ascending 

 above level of the eyes, third joint half its length, slender ; legs slender ;

Forewing broad, costa arched, exterior margin slightly convex, 

 posterior margin nearly straight ; cell broad, extending to half length 

 of the wing, costal vein extending to half the margin ; first subcos- 

 tal emitted at two-fifths and second at one-fourth before end of the cell, 

 third bifid at nearly two-thirds from the base ; discocellular slender, 

 slightly bent outward in the middle ; the radial from its angle ; lower 

 median at one-third and middle median from close before end of the 

 cell ; submedian straight : hindwing broad, costa abruptly arched at 

 the base, apex convex, exterior margin oblique and sinuous from middle 

 median, anal angle lobed, with a slender tail from lower median and 

 another from submedian ; costal and subcostal joined together for a

 ture, and extending to the apex ; first subcostal emitted at one-fifth be- 

 fore end of the cell ; discocellular outwardly oblique and bent outward at 

 the middle ; the radial from its angle ; cell broad, extending to nearly 

 half the wing ; lower median at one-third and middle median from im-
