tinues across the wing following the cord to the fork of Cu; wing- 

 base and wing-tip very slightly darker than the ground-color; veins 

 pale brown, more yellowish in the costal region, darker in the infus- 

 cated areas. Venation: Sci ending a short distance beyond the 

 fork of Rs, Sci at the tip of Sci; Rs straight, in alignment with the 

 basal deflection of Ri + o', cell Ri very long, the sides parallel; r-m 

 distinct, about one-half of 711; cell 1st M2 rectangular, a little longer 

 than vein Cih beyond it; basal deflection of Cui about one-half to 

 its full length beyond the fork of M. Abdomen reddish brown, 

 with a black subterminal ring on segments seven and eight. Male 

 hypopygium with the shortest pleural appendage with the tip black- 

 ened, produced into a simple curved hook; in R. 7nirabilis the ex- 

 treme tip is bifid.
