THYRIDIDAE OF AFRICA AND ITS ISLANDS 55 



the ostium is similar to N. fuliginea but N. joccatia can be distinguished from this 

 species by size and colour. From N. inoptata it can also be separated by size 

 and shape of the sclerotized part of the VHIth segment. N. joccatia is a more orange- 

 brown colour than the related N. antiopa Viette from Madagascar and the base of the 

 sacculus of antiopa has a small sclerotized hook whereas joccatia has a large group of 

 spines. Some variation exists in the colour and pattern of specimens of N. joccatia, 

 particularly in the presence or absence of a translucent area in the fore wing, and in 

 some specimens, a distinct, darker brown, median patch in the fore wing. Variation 

 in the shape of the basal process of the male was also found. For separation from 

 N. clathrula see page 56.

<J. Wing, 13-17 mm. Vertex brown. Labial palps with third segment 1/3 length of second, 

 upturned, reaching vertex, nearly 2 X diameter of eye. Frons with tuft of scales produced 

 between eyes. Patagia grey-brown, rest of thorax similar. Hind tibia with scale tuft. Outer 

 spur of distal pair on hind tibia slightly more than 1/2 length of inner spur. Fore wing, pattern 

 as in PI. 5, fig. 17, grey-brown with prominent fenestrations. Radial veins from cell. Under- 

 side paler than upper, mauve coloured with some brown patches. Fenestrations prominent. 

 Small white line over vein at apex of cell. Hind wing, colour and pattern as fore wing. Under- 

 side, as underside of fore wing.

 in first part, rest of duct broad, minutely spined. Bursa minutely spined. 



Discussion. This species was previously known from the female holotype only 

 and the country of origin was unknown. Two of the specimens examined (a male 

 and a female) match the pattern of the type-specimen. The other specimens are
