spots, posterior of these apical and fasciate; a large black blotch 

 along lower edge of cell from well beyond base to middle, edged below 

 by a large, strongly raised and expanded tuft of black and white 

 scales; another such blotch, shorter, in lower angle of cell; an undulate 

 black fascia along closing vein, with several slender branches in cell, 

 upper half of fascia much dUated ; a longitudinal grey suffused blotch 

 from lower angle of cell almost to termen; a well-defined black trans- 

 verse blotch parallel to termen, on 3/4 of dorsum, its posterior edge 

 with a strong semioval excision from below top almost to base; top 

 of this mark connected by grey suffusion with apical patch; terminal 

 edge irregularly white except below middle, dorsum paler, with four 

 transverse wedge-shaped light tawny marks and a blackish suffused 

 basal spot. Cilia grey mixed with white, tips white, basal third 

 unicolorous dark grey, three slender dark grey bars opposite middle 

 of termen, extending from base to top of cilia. 



Hindwing dark purplish fuscous, darker towards apex, cUia paler, 

 with a light basal line and a darker subbasal band. 



Male genitalia: Uncus halves moderate, attenuated, tips acutely 

 produced and slightly sinuated. Gnathos traceable, slightly sclero- 

 tized, triangidar. Valva narrower at base than in S. ejectana but 

 less constricted; cucullus with a single triangular and submembranous 

 ventral process, thorn above this rather small and not depressed. 



Material examined: Mindanao, Davao Prov., east slope of Mt. 

 McKmley, 7200 ft., 10.IX.1946, mossy stunted forest (CNHM 

 Philippine Exped. 1946-47, H. Hoogstraal), 1 cf , holotype, genit. 

 slide 5728; 1 cf , paratype.
