THYRIDIDAE OF AFRICA AND ITS ISLANDS 145 



Discussion. This species is similar to K. maculanota. It can be separated from 

 that species by the larger amount of white in the pattern of culanota. The round 

 white spot on the fore wing of maculanota is not present in culanota. The males can 

 be separated by the shape of the gnathus and the median basal process. The antennal 

 ciliations are shorter in the male of culanota than in maculanota. The females can be 

 separated by the shape of the first part of the duct and by the presence of some large 

 spines in the bursa of maculanota, these are absent in culanota. Both species occur 

 in Zambia and Rhodesia but the size variation in culanota is greater than in macula- 

 nota.

 third segment 1/3 length of second, upturned, reaching vertex. Thorax brown. Hind tibia 

 with outer spur of distal pair 1/2 length of inner spur. Inner spur almost equal in length to 

 1st hind tarsal segment. Fore wing, pattern as in PI. 17, figs 87, 88, reddish brown with thin, 

 black, median fascia, black spot at apex of cell and black reticulate pattern. Underside with 

 more prominent transverse fascia. 1A and iA fused near base to give single vein to wing 

 margin. Hind wing, colour and pattern as fore wing. Sc-\-R x and Rs approach but do not 

 join, i?! very weak near base of wing.

 "U"-shaped piece. Valve simple, basal part of costa produced inwards, joining slender transtilla. 

 Basal process spiny, with lateral tooth. Juxta with sclerotized lateral lobes, heavily toothed 

 on inner margin of each lobe. Saccus slightly elongate. Vesica of aedeagus with minute 

 spines, some small spines on manica.
