dark purplish fuscous, fringe of lower edge suffused with fuscous on 

 lower half throughout, terminal segment with a strongly oblique 

 median band. Antenna creamy. Thorax creamy yellowish. Abdo- 

 men creamy yellowish, venter yellowish white with a pair of sublateral 

 narrow black stripes, valva with a median black stripe. Posterior 

 tibia creamy white, posterior half of upper edge with an expanded 

 tuft of scales, triangularly prominent at the beginning, rounded at 

 the end, pale gre3dsh ochreous, appearing grey in certain hghts. 



Forewing sublanceolate, rather narrow. Creamy, with numerous 

 fuscous-gi'ey transverse strigulae, scattered all over the wing, except 

 along costa anteriorly; base of costal edge suffused with grey; an 

 inwards-oblique grey transverse mark from costa well beyond base, 

 dilated at the end, not reaching base of wing; plical stigma larger 

 than other markings, round, at 1/3 of wing length. Cilia whitish 

 ochreous, tinged brighter yellow along costa and around apex, opposite 

 apex tipped slightly with dark. 



Hindwing semipellucent pale golden yellowish, veins deeper yellow. 

 Cilia whitish yellow. 



The female posterior tibia (missing in the holotype) is covered with 

 roughly rising scales along anterior half, with a triangular dense tuft 

 well before apex and a rounded tuft at apex, in fact similar to that in 

 the male, but more infuscated above and beneath, with a broad dark 

 fuscous band including the triangular tuft. Spurs dilated by a fringe 

 of bristly grey scales along posterior edge. 



Male genitalia rather differing from these of the type species, T. 

 torvella Walker. Tegumen similar, but less sclerotized, less narrowed 

 tops simply truncate. Vinculum moderate, annular; saccus very 

 long, slender. Valva semiconical, concave, broad at base, cucullus 

 narrowed, conical, rounded. Sacculus represented by a thin marginal 

 rod and a second ventral top of valva, with a large transverse fila- 

 mentous top. Costa of valva with a moderate triangular hairy 

 process. There is a slender process at the middle of the base of valva, 

 directed rostrad. Anellus moderately oval, forming a central tube. 

 Aedeagus extremely long and slender. 



Female genitalia: Eighth tergite dilated, oval. Sterigma strongly 

 sclerotized and hairy, shaped as an inverted large W. Ostium small, 

 dilated at the top. Ductus and corpus bursae simple, unarmed, finely 

 transversely plicate.
