numerous small dark transverse strigulae, posterior half with three 

 or four marginal streaks alternating with minute transverse marks 

 and slightly edged below with yellow; this color becoming deeper, 

 tawny orange posteriorly and forming a well-defined streak below 

 posterior part of costa and just before apex, halfway to vein 7; a 

 faint dark suffusion on base of dorsum; a well-defined roundish patch 

 of dark fuscous irroration on middle of dorsum, reaching to upper 

 edge of cell, slightly extended basad along its lower edge; a more or 

 less defined wedge-shaped patch of dark fuscous irroration before 

 termen, from below costa almost to tornus, interrupted in its middle 

 by yellow suffusion along veins; a circular jet-black spot above middle 

 and against posterior edge of last mentioned patch, containing an 

 oval pale blue metallic dot towards its lower edge; edge of termen 

 narrowly fuscous, interrupted between veins, preceded by light yellow, 

 before these a thick slightly raised shining silvery-leaden streak paral- 

 lel to and before edge of wing, from end of vein 9 to that of vein 4. 

 Cilia pale yellow, a leaden-grey band from apex to 3/4 of termen, 

 cilia beyond this band irrorated and slightly mixed with dark leaden 

 grey. 



Hindwing rather dark brownish fuscous with some yellowish tinge, 

 cilia brownish fuscous with pale yellow base and a darker subbasal 

 band, beyond this band and between ends of veins 6 to 3, cilia pale 

 yellow, narrowly barred with fuscous opposite these veins. 



Male genitalia: Tegumen triangular, strongly down-curved. Uncus 

 rather rounded and thickened, long-haired in middle, bifid, halves 

 beak-shaped (broader than in hybristis). Socii absent. Gnathos 

 strong but arms rather narrow, wide; hood represented by a curved, 

 denticulate horizontal rod. Vinculum large, elongate (shorter than 

 in hybristis). Transtilla membranous, ill defined, inverted trape- 

 zoidal. Diaphragma forming a thickened transverse ridge, trape- 

 zoidal, with a granulate structure. Valva long and narrow, simple, 

 concave lengthwise; costa slightly modified and a little thickened, 

 3/4, sacculus moderate, under 1/2; cucullus radially wrinkled with 

 two long thorns on lower edge. Aedeagus moderate and rather 

 slender, gradually dilated basad and with a rounded base, top obliquely 

 truncate. Cornuti, a sheaf of not numerous long and slender spines, 

 undulate at their bases, and a fasciate patch of dense fine spines. 



Female, neallotype, 20 mm. Fore- and hindwings slightly narrower 

 than in male. Shining scaling on forehead less extended. Fuscous 

 suffusion of forewing more extended, transverse strigulae beyond cell 

 darker, continuous. Otherwise in all respects, also in the length of 

 palpi, similar to the male. 



Female genitalia: Lobi anales slender and elongate. Sterigma in- 

 verted trapeziodal, laterally ill defined; lamella post vaginalis, a simple
