Discussion. This species is similar to sigillata and jejunalis. From the former 

 it can be separated as given in the discussion under sigillata, and from jejunalis by 

 the more conspicuous spots on the hind margin of the hind wing of plagalis. In the 

 genitalia the shape of the median basal process of the male and the twin signa of the 

 female separate this species from the others in the genus.

o*. Wing, 12-14 mm - Vertex whitish brown, frons pale brown. Labial palps with third 

 segment 1/2 length of second, upturned, reaching vertex. Thorax whitish brown. Hind tibia 

 with outer spur of distal pair 1/2 length of inner spur; inner spur of distal pair almost as long as 

 1st hind tarsal segment. Distal and proximal spurs similar in length. Fore wing, pattern as 

 in PI. 20, fig. 103, whitish with pale grey markings. Prominent black discal spot. Apex and 

 terminal margin with black spots between veins. Veins yellowish. Underside greyer, pattern 

 darker. Discal spot prominent, iridescent scales in line subcostally. Hind wing, similar colour 

 and pattern as fore wing, black, usually double, mark on median hind margin. Underside, 

 as underside of fore wing but without iridescence. Sc+R 1 approach but do not join. 



Genitalia <$ (PI. 43, fig. 246). Median basal process reaches almost to hind margin of valve. 



$. Wing, 16—17 mm. Colour and pattern as male. Labial palps reaching above vertex. 



Genitalia ? (PI. 65, fig. 413). Signum generally triple, occasionally with small additional 

 patch. 



Discussion. The type-specimen of this species is a female and I am uncertain 

 whether the males described above are correctly associated. Externally they appear 

 similar to the females. This species is generally larger than the others in the genus.
