than most specimens of scopulepes, the apparent darker ground 

 color being the result of different lighting and other photographic 

 techniques. Because of space limitations, the underside of the 

 wings of aurora have not been figured. In the single female the 

 maculation of the underside is similar to that of zayasi, but the 

 maculation of the underside of the hindwings in the males agrees 

 more closely with that of scopulepes in regard to the development of 

 the transverse lines. 



Hemeroplanis zayasi, new species 

 Figures 1, 4; Plate 1, Figures 1-3 



Description: Head with front only slightly exceeding eyes; front 

 narrow, about equal in width to eye. Eyes moderately large, globoid, 

 naked. Ocelli present. Antennae filiform, weakly ciliate ventrally. 

 Labial palpi slightly oblique, nearly porrect, reaching about to middle 

 of front, clothed with small, appressed salmon pink and dull brown, 

 pale-tipped scales. 



Vestiture of front and patagia mostly of dull brown, pale-tipped 

 scales, many bifid and hairlike. Vestiture of tegulae and thorax of 

 yellow hairs over pale yellow scales. Abdomen yellow suffused with 

 brown scaling. Large, white, lateral tufts of basal abdominal segment 

 extending ventrad, covering abdominal sternites of basal segments. 



Legs of male with femora and tibiae conspicuously tufted (fig. 1), 

 tufts mostly salmon pink except distal tuft of hind femur black. 

 Tibia of middle leg short. Basal tarsal segment enlarged, densely 

 scaled (fig. 1). 



Forewing about half again as long as wide (13:8); slightly falcate 

 apically; termen weakly angulate at Cuij venation of quadrifid type, 

 areole present in forewing. Maculation of wings as illustrated (pi. 1, 

 figs. 1-3). Ground color of wings of male basad of postmedial band 

 pale lemon yellow irrorated with brown, area distad of postmedial 

 band rust brown. Ground color of wings of female variable, orangish- 

 yellow, olivaceous or salmon brown, darker distally. Subterminal 

 spot between Cu 2 and anal vein of forewing of male black; anal spot 

 of hindwing of male salmon; elements of transverse band (when 

 present) reniform and orbicular spots dull brown. 



Underside colored about as upperside, except ordinary spots and 

 lines darker brown, and terminal area paler. 



Male and female genitalia specifically distinct (fig. 4). Uncus of 

 male genitalia (fig. 4c) shorter and stouter than that of scopulepes 

 but longer than that of aurora; apex of uncus membranous ventrally. 

 Processes of inner face of valve larger and more heavily sclerotized in 

 zayasi than in the other two species (see figs. 4a, 5a, and 6a). The 

 aedeagus of zayasi shorter and stouter than that of scopulepes, longer
