present, small. Thorax brown. Fore tibia with epiphysis. Hind tibia with two pairs of 

 spurs, outer spur of distal pair almost equal to inner spur, much shorter than ist hind tarsal 

 segment. First hind tarsal segment shorter than tibia, tarsal segments 1-4 without spines, 

 last tarsal segment on each leg with a group of spines. Fore wing, pattern as in PI. 22, fig. 

 118, grey-brown with darker transverse markings and a prominent black mark over apex of 

 cell. Radial veins from cell. Underside, as upperside but paler. Hind wings, colour as fore 

 wings, underside paler than upper. Sc + R 1 and Rs free. Frenulum absent, area in front of 

 Sc+Rt enlarged. 



Genitalia <J (PI. 46, fig. 263). Uncus simple. Valves simple, apex slightly broader than 

 half way along. Basal process sclerotized, sinuous. Juxta two small lateral lobes. Vesica 

 of aedeagus without spines. 



$. Wing, 17-21-5 mm. Antennae ciliate without the pectinations of the male. Colour 

 and pattern as male. Frenluum absent. 



Genitalia $ (PI. 67, fig. 435). Anal papillae short. Ostium broad, covered with minute 

 spines. Duct and bursa covered in minute spines. 



Discussion. Some of the similarities between insolita and confusa are remarkable, 

 the male genitalia are very similar although the aedeagus of insolita has spines in the 

 vesica. The wing pattern is similar but confusa has a prominent black mark over 

 the cell and the radial veins differ slightly in their origins. The most striking 

 difference between the two species is the absence of the epiphysis on the fore tibia of 

 insolita and only a single pair of spurs on the hind tibia (see also under insolita).

LELYMENA Karsch 



Lelymena Karsch, 1900 : 251. Type-species, Lelymena misalis Karsch, by monotypy. 

 [Rhodoneura sensu Gaede, 191 7 : 360, nee Guenee.] 

 [Rhodoneura (partim) sensu Whalley, 1964a : 125, nee Guenee.] 



This genus is retained for the single species L. misalis Karsch. This species is 

 unlike any other Thyridid in colour and pattern, the pale lemon-yellow wings and 

 absence of the typical thyridid reticulate pattern make this species unique in the 

 family. The wing venation is variable, even varying between the left and right 

 sides of the same specimen. There is also a tendency for some of the specimens to 

 develop transverse veins, this has not been found in any other species of Thyridid, 

 however the peculiar colouration of L. misalis with the black scales lining the wing 

 veins makes any anomalous situation obvious. 



There are no clear affinities of this genus. It can be separated from Rhodoneura 

 by the lack of the spines on the tarsal segments. Certain features of the genitalia of
