Generic description. Eyes without interfacetal hairs. Proboscis present. Antennae 

 minutely ciliate. Labial palps, long, 3-segmented. Radial veins of fore wing from cell. Hind 

 tibia with single, prominent, median spur, usually slightly clavate, and distal pair of spurs. 

 Tarsi without spines. Fore tibia with epiphysis. Uncus in male usually broad at base. Lobes 

 of juxta with medial spines.

o*. Wing, 8-10 mm. Vertex light brown. Labial palps with third segment 1/2 length of 

 second, upturned, reaching vertex, palp 2 X diameter of eye. Hind tibia with distal pair of 

 spurs as long as 1st hind tarsal segment. Proximal pair of spurs with one spur modified to form 

 a long, thin, scale-like process with thickened end, other spur of proximal pair reduced, not 

 visible through scale cover. Base of long proximal spur enlarged (covered by scales). Fore 

 wing, pattern as in PI. 16, figs 83, 84, light brown with darker brown transverse fascia and black- 

 reticulations, often with purplish suffusion. Costal margin with faint brown and white markings. 

 Underside with prominent scattering of black and silver scales along hind part of cell, with 

 some at apex of cell. Hind wing, pattern as fore wing, often with purplish suffusion. No black 

 scales on underside. Sc+R x and Rs approach closely but do not fuse. 



Genitalia <J (PI- 4°. figs 226, 227). Uncus broad, narrowing near apex, base slightly pro- 

 duced laterally. Gnathus present with median process covered with minute spines. Juxta 

 with two lateral lobes, apex of lobes produced on inner edge to form blunt process, inner edge 

 of lobe with long spines. Valve simple, basal process weakly sclerotized. Aedeagus with 

 mass of small cornuti. 



$. Wing, 9-9-5 mm. Colour and pattern as male. Hind tibia with inner spur of proximal 

 pair modified, but not as strongly as male. 



Genitalia $ (PL 59, figs 362, 363). Anal papillae short. Ostium covered with small spines, 

 first part of duct lightly sclerotized, minutely spined. Bursa covered with minute spines. 



Discussion. The modified tibial spurs are also found in B. galbana but the 

 modifications are not as extreme as in C. subscripta. There is some variation in 

 colour and pattern and there is probably some subspeciation but insufficient material 

 was available to check this. A characteristic of this species is the single long, 

 slightly clavate, proximal tibial spur. Externally this species is similar to C. 

 obstinata but the genitalia are distinct. The strongly spined juxta is also found in 

 K. ansorgei but this species can be separated from subscripta by the longer ciliations 

 of the antennae, by the longer process of the gnathus and bigger spines in the 

 aedeagus of subscripta. In the females, the two species can be separated by the 

 shape of the ostium and the duct of the bursa.
