side forming a straight line and getting very short beyond frd of shaft; 
legs rather short, especially the fore legs; fore tibia of $ with a pointed 
process on inner side, as long as tibia and covered with long dense hairs on outer 
side; in $ the process is narrow and the hairs are shorter; tarsi short and with

which is well rounded; inner margin curved at half; i b well forked at base; 
2 from beyond |th lower median ; 3 from frd 2 to 4 ; 4 from lower angle and much 
curved; 5 from frd discocellulars, which are erect and somewhat curved; 6 
slightly stalked with stalk of 7, 8, 9, 10 which comes from upper angle; 7 from 
stalk at frd of 8; 8 to apex; 9 from 8 beyond frd of 8; 10 from stalk, 8, 9 at 
before middle of 8; 11 from upper median at fth; 12 parallel to costa except 
near base where it is curved. Hind wing sub-triangular ; costa well arched; 
apex rounded; outer margin oblique, well rounded at vein 3, somewhat 
incurved between 4 and 6, 2 and 3; tornus and inner margin rounded; 1 a and 
1 b slightly curved ; 2 from lower median at frd ; 3 from fth 2 to 4 ; 4 from lower 
angle; 5 absent, only a mere trace of it can be seen; discocellulars very oblique 
at lower half, then more erect; 6 and 7 stalked for about frd of 6; 7 well curved 
at tip; 8 slightly curved at base, then approximated to upper median beyond 
middle, but not touching it, then upcurved beyond frd and downwards towards 
tip. 
Range: N. America, Europe, Asia, Africa. 
The three South African species may be distinguished as follows : 
1 a. Transverse lines almost absent; where the medial and postmedial lines 
should be the ground colour is slightly lighter ; fore wing vinaceous- 
lilac, irrorated with morocco-red, especially at the costal area 
violacearia 
b . Transverse lines distinct ; fore wing along the costa of ground colour 
or lighter ........... 2 
2 a. Tuft of thorax in front and hairs of frons mummy-brown; hind wing 
as dark as fore wing; apical part of fore wing buckthorn-brown; 
reniform oval; sub-terminal line consisting of rather irregularly 
placed spots lentisignata 
b. Colour of thoracic tuft orange-cinnamon; hind wing lighter than fore 
wing; fore wing with the apical and terminal part lighter than 
ground colour; reniform round; sub-terminal line almost con- 
tinuous roseotincta

I have one $ in my collection which agrees well with the description 
except for the oblique dark shade in the fore wing from postmedial line at
