Kuja gemmata (Hampson) comb. n. 

 (PI. 12, figs 59, 60; PL 37, fig. 205; PI. 60, figs 364, 365)

cj. Wing, i2'5-i9'5 mm. Vertex dark brown, irrorate with yellow scales. Frons brown, 

 not swollen. Labial palps with third segment 1/3 length of second, upturned, reaching vertex. 

 Length of palp approximately equal to diameter of eye. Thorax reddish brown. Hind tibia 

 with inner spur of proximal pair slender with clavate end, outer spur of distal pair slightly more 

 than 1/2 length of inner spur, inner spur of distal pair 1/2 length of 1st hind tarsal segment. 

 Fore wing, pattern as in PI. 12, fig. 59, reddish brown with lighter fringes, light reticulations and 

 transverse pattern. Underside paler, five or six patches of black scales surrounded by yellow 

 scales in cell (PI. 12, fig. 60), apex of cell with scattered yellow scales. Hind wing, colour and 

 pattern as fore wing but no black and yellow spots on underside. Sc+R 1 and Rs approaching, 

 but not joining. Base of Rs and M x obsolete, M, from cell. 



Genitalia <$ (PI. 37, fig. 205). Uncus with strong lateral "wings". Aedeagus with cornuti. 



$. Wing, 17-25 mm. Colour and pattern as male. Labial palps with third segment 1/2 

 length of second. Hind tibia with proximal spurs as large as distal pair, not slender and clavate 

 as in male. 



Genitalia $ (PI. 60, figs 364, 365). Anal papillae broad. Ostium and part of duct strongly 

 sclerotized. 



Discussion. This species is very closely allied to K. catenula from which it can 

 be separated by the much darker brown colour (almost mahogany colour), by the 

 shape of the lateral process on the uncus and the length of the gnathus. In the 

 female, the duct of catenula is less heavily sclerotized in the first part near 

 the ostium than in gemmata.
