Most (8 of 9) have five subapical macules, one has only four. The two females seen (FW length = 36.1 mm , n = 1) are superficially very similar to N. solon (see above). Male genitalia ( Fig. 119 ) are more or less as illustrated by Evans (1952) ; those shown by Williams and Bell (1934) as Nascus broteas are of N. solon . Female genitalia ( Fig. 122 ) have a narrow and quadrate lamella postvaginalis with a deep Vshaped central notch on its caudal edge. The central portion of the lamella antevaginalis is rectangular, has a central U-shaped notch on its caudal edge, overlays nearly the entire ostium bursae, and nearly reaches the caudal edge of the lamella postvaginalis.

Nascus broteas is uncommon near Cacaulândia, with records for June through November ( Fig. 130 ). The species is known from Mexico (north to San Luis Potosi ) to Argentina , Paraguay , and southern Brazil ( Evans 1952 , Freeman 1976 , Cock and Alston-Smith 1990 , de la Maza and White 1990, Warren 2000, Nuñez Bustos 2006).
