Cecidothyris chrysotherma (Hampson) comb. n. 

 (PL 23, fig. 122 ; PL 47, fig. 266 ; PL 68, figs 440, 441)

 Betousa chrysotherma Hampson; Gaede, 1917 : 370. 

 Betousa chrysotherma Hampson; Gaede, 1929 : 496. 



o". Wing, 13-14 mm. Vertex yellowish brown, frons rounded, only slightly protruding 

 in front of eyes when viewed laterally. Clypeus with small sclerotized point (not visible 

 through scales.) Antennae strongly bipectinate. Labial palps short, not reaching vertex. 

 Thorax, tegulae, brown irrorate with white scales. Hind tibia with outer spur more than 1/2 

 length of inner spur. Fore wing, pattern as in PI. 23, fig. 122, dark brown with paler subterminal 

 areas. Slight pinkish tinge to median and ante-median areas. Costal margin irrorate with white 

 scales giving a grey appearance. R 3 and i? 4 with common stalk. Vein \A and iA free at base, 

 joining to form single vein to wing margin. Underside, paler than upper, median brown area 

 reduced in size. Hind wings, colour as fore wing, median area, narrow, brown. Sc+R t and 

 Es free, cell almost closed. 



Genitalia $ (PI. 47, fig. 266). Uncus simple, gnathus present with slight projection in centre. 

 Aedeagus with minutely spined vesica. 



$. Wing, 15-18 mm. Antennae serrate, colour and pattern as in male but median brown 

 fascia on fore wing with lighter centre than male. 



Genitalia $ (PI. 68, figs 440, 441). Anal papillae short, neck of duct with short, chitinized, 

 part near ostium. Bursa without signum. 



Discussion. The dark brown colour of this species is constant but the pattern 

 is slightly variable. From C. p. guttulata it can be distinguished in the male by the 

 more lightly patterned underside and the genitalia. The female of C. p. guttulata 

 has a broader median fascia in the hind wing than C. chrysotherma, otherwise these 

 two species are similar. Generally C. p. guttulata is larger and darker than C. 

 chrysotherma.
