genitalia with signum and with ductus seminalis from the bursa. It 

 is nearest to Eremberga, but that genus is broad-winged and has a 

 flat, more strongly sclerotized anellus, a scobinate aedeagus, stouter 

 male genitalia, no signum, and the ductus seminalis coming from the 

 ductus bursae. In Tueumania the wings are long and rather narrow. 

 The known distribution is Argentina and Uruguay.

 Tiicumania tapiacola Dyar, Insecutor Inscitiae Menstruus, vol. 13, p. 225, 1925. 



Male.—Psdp'i, face, head, thorax, and fore wings dark grayish 

 fuscous with a sparse scattering of obscure whitish scales (Dyar 

 states that the coxae and parts of the femora and tibiae of the legs 

 are black, but even on these parts there is some scattered pale scaling 

 and the ground color is fuscous rather than black). Fore wing 

 almost uniformly dark, sometimes a very faint luteous tint in the 

 median area and a slight pale suffusion in terminal area; transverse 

 lines black but not strongly contrasted against the dark ground color; 

 antemedial line bidentate, its apex extending almost to center of cell ; 

 subterminal line dentate, sinuate, the dentations short, bordered out- 

 wardly by a pale line and beyond this by a rather broad blackish 

 band, from costa well before apex; apical spot at end of cell large; 

 veins beyond cell faintly outlined by dark scaling; a row of black 

 dots along termen at the vein ends. Hind wing whitish, semihyaline, 

 strongly shaded with fuscous at apex and narrowly along margin of 

 termen almost to anal angle. 



Alar expanse, 27-28 mm. 



Genitalia (figs. 17-17c) with apex of harpe bluntly pointed ; anellus 

 with the apices of the arms appreciably broadened. These are pre- 

 sumably specific characters. I have seen no males of any other species 

 of Tucumania. 



Female. — In color and markings like the male except that the 

 fuscous shading on the hind wing is a trifle more extended. 



Alar expanse, 30 mm. 



Genitalia (figs. 59-59a) with scobinations of bursa very weak and 

 distinguishable only in area surrounding signum; signum somewhat 

 granulate.
