densely pubescent ventrally, with minute spicules present laterally 

 and ventrally. Vestiture of patagia, tegulae, and thorax a mixture of 

 pale yellow hair and scales; a slight decumbent, metathoracic crest 

 present. Abdomen orange dorsally and laterally, pale yellow ven- 

 trally with lateral and/or terminal black scaling on segments 3 through 

 7; dorsal tufts absent. Pectus clothed mth large, pale yellow or 

 white scales and long, sparse, white hair; tympanum nearly covered 

 by very large akdar fan of broad yellow scales. Legs mainly pale 

 basally, dark distally ; foreleg with tibia and tarsus dark brown except 

 small white spot at middle of tibia and white rings at base and apex 

 of first tarsomere and apex of second; middle leg pale yellow except 

 for dark brown knee spot, broad apical brown band on tibia (includ- 

 ing spurs) and dark tarsus, tarsomeres 1 and 2 marked with white 

 like those of foreleg; hindleg colored like preceding leg except dark 

 knee spot absent. Venation of wings as for genus. Maculation of 

 male similar to that of irretita (see figs. 1 and 2), except that outer, 

 dark costal mark of forewing is distinctly looped basad immediately 

 above lower angle of cell and terminal orange line extends around 

 apex of wing. Basal half of upper surface of forewing lemon yellow, 

 transverse lines black, subterminal oblique mark and fringe slate gray. 

 Upper surface of hindAving orange around margins, white medially, 

 a fuscous spot at apex. Ventral surface of forewing with ground color 

 orange, median and apical costal marks, subterminal oblique mark 

 and fringe dark fuscous or black ; hindwing ventrally like upper surface 

 except orange of costa brighter and small postmedial and antemedial 

 spots present. Female colored as in male except upper surface of 

 hindwing orange with broad marginal fuscous band, the latter in- 

 curved slightly at Cu2; ventrally postmedial fuscous mark extending 

 nearly to anal angle, broadest between M2 and caudal end, antemedial 

 spot variable in size, absent in one specimen. Length of forewing: 

 male, 12 mm.; female, 12 to 13 mm. 



Male genitalia of type specimen partially destroyed by dermestids; 

 however, the valves are preserved and are distinctive (fig. 21). Right 

 valve enlarged, much broader than left valve, sacculus broad, pro- 

 duced and curved toward costa at apex, a longer, curved process 

 developed immediately distad of sacculus from near ventral margin of 

 the valve. Female genitalia as illustrated (fig. 20), ductus bm-sae 

 broad, rather long, only slightly sclerotized; caudal margin of seventh 

 abdominal sternite not asymmetrical as in the females of the splendens 

 complex. 



Types: Type male and two female paratypes, Alta Gracia, La 

 Granja, Sierras de Cordoba, Argentina, C. Brucli, in the private collec- 

 tion of P. Kohler, Buenos Aires, Argentina. One female paratype,
