slightly larger, with longer posterior extremities, and of more 
yellowish coloration.

ethiopica. Humeri and proximal halves of forearms clothed 
with fur, which also extends on to the wing-membrane. 
Base of interfemoral membrane and proximal halves of femora 
also hairy. Below, the fur extends further back on the 
wing-membrane, but less on the interfemoral than above. 
General colour above dull buffy, not far from Ridgway’s 
“¢ clay-colour,” browner posteriorly and on the humeri. — Indi- 
vidually the hairs are glossy buff, with brown tips. Below, 
ihe colour throughout is clear buff, very near Ridgway’s 
pl. v. fig. 13.
