5 o A. WATSON 



Patagia pale yellow (2A3), each with black spot posteromedially ; tegulae pale yellow; rest of 

 dorsal surface of thorax pale yellow but with large, black, medial spot anteriorly. Ventral 

 surface of thorax dark brown (nearly black) except for deep orange immediately behind head 

 and pale yellow near wing bases. Foreleg coxa deep orange, rest of leg dark brown; midleg 

 dark brown except for streak of yellowish white at distal end of outer surface of femur in some 

 specimens (not type) ; hindleg as midleg. Forewing pale yellow (2A3) ; hindwing slightly 

 paler, its outer margin weakly concave. Dorsal surface of abdominal segments 1 and 2 dark 

 brown (nearly black, with weak, dark blue iridescence) ; 3 dark brown medially, orange laterally; 

 4 as 3 but with narrower, dark brown area; 5—8 orange, each with dark brown, medial spot at 

 anterior margin of segment; 3-8 with dark brown lateral spot at either side of anterior margin 

 of each segment; ventral surface of 2 dark brown except for orange posteromedial patch; 3 

 orange with dark brown, lateral patch on each side ; 4-8 orange, each with dark brown, lateral 

 spot. 



9. As $, but outer margin of hind wing very weakly concave (type), straight or convex, 

 and ventral surface of terminal (7th) segment of abdomen dark brown except for orange anterior 

 area. 



Forewing length: lectotype § 31*0 mm; <$ 24-5-26-0 mm; O- 27-5-31-0 mm. 



(J genitalia. Valves tapered, apex truncate ; uncus with weak dorsal carina, strongly carinate 

 ventrally with anteriorly directed spine at middle; aedeagus arcuate, without apical process. 



$ genitalia. Signa small; ductus bursae membranous except for narrow posterior band; 

 lamella antevaginalis weakly emarginate medially; lamella postvaginalis strongly emarginate 

 medially; scent tubules relatively short. 



Most likely to be confused with pseudelissa from which it differs chiefly in the 

 presence of a dark brown spot on each patagium and a circular or ovoid medial 

 spot on the thorax (in contrast with a longitudinal band is pseudelissa) . Similarities 

 in the genitalia suggest that a close relationship exists between schausi and pseudelissa.

9- Palp short, extending to about one-quarter distance between labrum and base of antenna. 

 Antenna bipectinate proximally, serrate distally. Head with conspicuous tuft extending 

 from dorsal part of clypeo-frons to posterior margin of vertex. Thorax mostly white and orange- 

 grey. Legs orange-red and white; mesothoracic legs with one pair of spurs; metathoracic 

 legs with two pairs of spurs. Tymbal organ well developed; with 25 microtymbals. Wings 

 uniformly white; venation as in figure. Abdomen white, with black, dorsal line. 



$. As $ but forewing narrower, and hind wing probably smaller relative to forewing [single 

 (J badly damaged]. There are no recognizable scent-organs on the wings. 



§ genitalia. Corpus bursae moderate in size; appendix bursae approximately equal in 

 size to latter. Ductus bursae sclerotized. Paired lamellae antevaginalis and single lamella 

 postvaginalis present. Scent tubules simple, short. Papillae anales broad.
