52 P. E. S. WHALLEY 



with scales, outer spur of distal pair 1/2 length of inner spur, longest spur less than length of 

 1st hind tarsal segment. Fore wing, pattern as in PI. 5, fig. 14, black with a few dark fascia. 

 Underside with lighter fascia and distinct red colour along costal margin. Veins \A and iA 

 forming an incomplete loop at base of wing, joining together near base and running separately 

 to margin. Hind wing, colour as fore wing, two distinct red fascia on wing. 



Genitalia $ (PI. 28, fig. 147). Uncus obscured in ventral view by development of socii as 

 two forward projecting arms. Uncus only clearly visible in side or dorsal view as long sclerotized 

 projection, articulating with a small raised boss. Gnathus a complicated double structure which 

 cannot be separated from a possible sclerotization of the subscaphium. Juxta highly modified, 

 "T"-shaped with dorsal lobe. Basal process with several sclerotized teeth. Valve simple, 

 blunt-ended, and heavily scaled. Aedeagus with small group of cornuti. 



$. Wing, 7 mm. Colour and pattern as in male. Third segment of labial palps over 1/2 

 length of second. 



Genitalia $ (PI. 50, fig. 287). Anal papilla short. Ostium with two sclerotized plates on 

 either side. Sclerotized first part of duct narrow, minutely spined. 



Discussion. The genitalia of the male are very distinct from most other African 

 Thyrididae. At present M. rnagica is the only known African species where the 

 eyes are not spherical. While there are differences in the genitalia between M. 

 magica and M. roseola Felder & Rogenhofer (the type-species of Mathoris) both 

 species have similar fore and hind wing venation and other aspects of the morphology 

 are very similar. The female of M. roseola has a very complicated ostium and in the 

 male the uncus is reduced but the twin socii and modified gnathus found in magica 

 are present in roseola. In some respects it would be possible to consider the two 

 species as belonging to separate genera but the number of similar features make it 

 preferable to indicate their possible relationship by keeping them in the same genus. 



In the few specimens of magica examined, two specimens have more white in the 

 basal and median areas (PI. 5, fig. 13), otherwise the remaining specimens are very 

 constant in their colouration.

NEOBANISIA Whalley 



Neobanisia Whalley, 1967 : 45. Type-species, Striglina antiopa Viette, by original designation. 



This genus contains four African species, one Madagascan species and one species 

 at present known only from Mauritius. 



The present description modifies slightly the original description of the genus 

 (Whalley, 1967 : 45) and may need some further modifications when species in 

 other faunal regions are studied. Neobanisia is part of the complex of genera which 

 includes Banisia Walker, Canaea Walker and Striglina Guenee. All these genera 

 have rather complicated genitalia in both sexes compared with the relatively simple 

 genitalia of other Thyridid genera. Neobanisia is related to Canaea but the female
