Female. Length 10 lines.—Black, covered with iridescent 
pile, which has a mixture of violet and blue shades; the meta-

Male. Length 5 lines.—Black: the metathorax has a central 
longitudinal impressed line, and is covered with short silvery

a broad red fascia which is covered with silvery pile ; legs slightly 
spinose. 
Hab. Albania. (Coll. W. W. Saunders, Esq.) 
Notwithstanding the difference in the colour of the wings, 
there are strong reasons for suspecting this species to be the 
male of F. distincta.

along the orbits of the eyes, slightly interrupted at their vertex.
