. with indistinct brownish streaks between the veins, the latter with 
white lines as in the preceding species ; discal line accompanied along 
its hinder side towards the base by a short, slight, black line, and con- 
tiguous in front at its tip to a diffuse brown mark ; exterior line, mar- 
ginal points, and hind wings as in the preceding species. Length of 
the body 7 lines; of the wings 15 lines. 
This species very closely resembles L. roseilinea, and there may be con- 
necting links between them; the chief difference is in the discal brown 
mark, which is not beyond but in front of the end of the white line.
