Forewing elongate subtruncate, costa with a broad prominence at 

 1/3, concave beyond this, posterior third rounded and slightly 

 scalloped, apex pointed and slightly produced (sublanceolate), termen 

 sinuate, concave above, rounded beneath, with rough tufts of raised

 posterior third of costa this brown streak is moderate, interrupted 

 three times on scallops by white raised tufts, fine sprinkling of different 

 shades of brown, arranged more or less in longitudinal rows, parallel to 

 veins, below costa; some finer, blackish speckling below posterior part 

 of costa and in apex; a small transverse group of blackish scales in 

 tornus; an elongate patch of raised scales on costal prominence, and 

 three rounded tufts of scales on scallops of the posterior thu-d of costa; 

 anterior discal stigma replaced by a large elongate raised tuft, reaching 

 to fold, above along base edged with blackish scales; a small blackish 

 raised tuft above this; second discal stigma replaced by a smaller, 

 roundish tuft, slightly postmedian, hardly edged with blackish;

 tornus. Cilia white, around apex and along upper half of termen 

 leaden grey, along termen with a submedian series of black strigulae, 

 each with some iiToration below it, these patches of irroration forming

 narrow in the middle, forming two subquadrate, hauy and large lobes. 

 Gnathos, two hemispherical processes with finely denticulate surface. 

 Valvae small, 2/3 length of tegumen, simple, subtruncate, fused along 

 basal half of their inner edge. Aedeagus rather thick along basal 

 half, apical half narrower. Neallotype, slide 5214. 



Female genitalia: Resembling those of Tonica citrantha, but the 

 sclerotized genital segment much shorter, with rostral edge of sternite
