THYRIDIDAE OF AFRICA AND ITS ISLANDS 41 



Chrysotypus reticulatus sp. n. 



(PI. 3. %• 5- PI- 26, fig. 139, PL 49, figs 283, 284) 



<3\ Wing, 19—20 mm. Vertex and irons dark brown, clypeus not swollen. Antennae 

 strongly pectinate. Labial palps with third segment 1/3 length of second, porrect, not reaching 

 vertex. Proboscis reduced. Patagium brown. Thorax brown, irrorate with white scales. 

 Hind tibia with two pairs of spurs, outer spur of distal pair slightly shorter than inner. Fore 

 wing, pattern as in PI. 3, fig. 5, yellowish brown with darker brown reticulations. Prominent 

 dark brown discal spot. Vein R i and R s anastomosing (in some specimens only approximating). 

 Hind wing with Sc+R 1 and Rs free. 



Genitalia <J (PI. 26, fig. 139). Juxta lobes 1/2 width of valve. 



$. Wing, 22-25 mm - Colour and pattern similar to male but antennal pectinations shorter. 

 Third segment of labial palps 1/3 length of second. 



Genitalia $ (PI. 49, figs 283, 284). Similar to C. circumfuscus but ostium narrower. 



Discussion. This species differs from C. circumfuscus in the venation of the 

 fore wing and in the shape of the juxta in the male. It also has two pairs of tibial 

 spurs on the hind leg, whereas the proximal pair is reduced or absent in circumfuscus. 



Little material of C. reticulatus is available but it appears to be the east and central 

 African replacement of C. circumfuscus. The single specimen from Uganda differs 

 in the shape of the juxta and the shape of the median process of the valve. It may 

 represent a distinct species but these structures vary in shape to such an extent that 

 more material is needed to confirm this. The venation of this specimen is typical 

 of the other specimens of reticulatus.

Chrysotypus subflavus sp. n. 



(PL 2, fig. I; PL 26, fig. 140) 



(J. Wing, 14-5-16 mm. Vertex yellowish brown, frons similar, clypeus slightly swollen. 

 Antennae strongly bipectinate. Labial palps with third segment 1/3 length of second, up- 

 turned, not reaching vertex. Proboscis very small. Patagium and thorax yellowish brown. 

 Hind tibia with two pairs of spurs, distal pair almost equal in length, apices of spurs pointed and 

 sclerotized. Fore wing, pattern as in PI. 2, I, pale sandy brown with darker costal margin 

 and triangular dark mark in distal area. Reticulations lightly marked.
