the fork of Rs, Sc. at the extreme tip of Sc,; Rs relatively 
short, gently arcuated; R,,3; but slightly sinuous, with 
macrotrichiz for its entire length, with the exception of a 
short space at the apex and origin ;_ basal deflection of Ry,5

Rhamphidia subobsoleta is closely allied to L. obsoleta, 
Alex. (Sievra Leone), from which it differs in the smaller size, 
the proportionately shorter rostrum, the darker wings with 
the stigma smaller and better defined, the darkened wing-tip, 
the smaller cell 1s¢ J/, and other details of coloration and 
venation.
