Habitat. Sokotra (Homhil, 2, as f.; 23/41./99, 13g; 19; ecahal Valley, 
near Homhil, 6/i./99, zd. 200 ft., 27/1./99, 1 9; Adho Dimellus, 3500 ft., 
11/ii./99). 
This species, which I have great pleasure in dedicating to Dr. H. O. 
Forbes, may be at once recognised by the inky black wings, with only a clear 
band just before the apex, which is smoky.
