There are two known species :— 
Body yellowish, hind wings yellowish between the anal margin and the proximal 
subbasal sector (A;), but no brown spot there, wings often a little brownish at 
tips, superior appendages of the male 3°5 mm. long, inferior appendage two- 
thirds as long. Abdomen, ¢ 29-33, ? 32-34; hind wing, ¢ 41-42, 9 39°5- 
41 mm. Be ee ew we 1. flavescens.

Herr Kriiger says’ of this species that it “variirt....so gut wie iiberhaupt nicht.” Variations in the 
venation do indeed occur, as in the number of antecubitals and postcubitals, in the density of the area 
between the subnodal sector and the supplementary sector next below, in the arrangement of the post- 
triangular rows, in the position of the proximal side of the triangle relative to the arculus of the hind 
wing, in the number of cells in the internal triangle of the front wing—but these variations do not 
appear to be peculiar to any particular locality.
