THYRIDIDAE OF AFRICA AND ITS ISLANDS 113 



Antennae broken, probably minutely ciliate. Labial palps with third segment 1/3 length of 

 second, upturned not reaching vertex. Patagia grey. Thorax white, irrorate with grey scales. 

 Hind tibia with outer spur of distal pair less than 1/2 length of inner spur. Fore wing, pattern 

 as in PI. 12, fig. 55, white with grey-brown costal markings enlarged in basal and median areas. 

 Rest of fore wing white with grey-brown markings. Veins R 3 and i? 4 anastomose. Underside, 

 as upperside but markings darker. Hind wing, white with prominent grey-brown transverse 

 fascia made up of two lines. Sc -fi?! and Rs free, Rs vestigial at base. Cell of hind wing closed, 

 with faint median vein present in cell. 2 A in hind wing very small. 



Genitalia <$ (PI. 36, fig. 199). Uncus simple. Gnathus a weakly sclerotized loop without 

 median process. Valve simple, basal process small, sclerotized with spiny end. Juxta, two 

 conical lateral lobes with a few spines at apex. Aedeagus broad near basal part with lightly 

 sclerotized band round middle. 



$. Unknown. 



Discussion. Although only one slightly damaged specimen of this species is 

 known it is sufficiently distinct from the others in the genus to be described. The 

 lightly sclerotized gnathus without median process differentiates this from pellucida, 

 inops and Candida. Externally it is more heavily marked than pellucida which it 

 most closely resembles.

Epaena vocata sp. n. 



(PI. 12, fig. 56; PI. 36, figs 201, 202) 



o*. Wing, 11 mm. Vertex and frons reddish brown. Labial palps short, equal to diameter 

 of eye, third segment 1/2 length of second, porrect. Prothorax brown, meso- and metathorax 

 white. Hind tibia with inner spur of distal pair 1/2 length of outer spur. Fore wing, pattern 

 as in PI. 12, fig. 56, creamy white with yellowish brown marks on termen and pale patches of 

 yellowish brown in median and basal areas. Underside similar, more yellow-brown scales 

 obscuring the white. Veins i? 3 and R x anastomose. Hind wing, median yellowish brown fascia. 

 Indistinct subterminal fascia, rest of wing creamy white. Underside paler, 5c +R X and Rs free. 



Genitalia q* (PI- 36, figs 201, 202). Uncus simple. Gnathus with long median process. 

 Valve simple, broad basal area. Juxta with 2 lateral processes, each with small spiny pad near 

 apex and median plate. Aedeagus with minute spines on vesica. 



$. Wing, 14-5 mm. Labial palps porrect, 2 X diameter of eye. Colour and pattern as 

 male but more suffused with yellowish brown. Abdomen missing. 



Discussion. This species is only known from two specimens of which the female 

 lacks an abdomen. The generic placing of this species is uncertain. Externally 

 E. vocata resembles a small specimen of N. fuscibasalis Hampson but the male 

 genitalia are distinct and fuscibasalis is without the fusion of the fore wing veins 

 found in vocata. Similarly N. fulvipicta Hampson has certain similarities in the 

 colour and pattern to vocata but that too lacks the fusion of the radial veins of the 

 fore wing.
