7. FERREOLA DISTINCTA. B.M. 



Female. Length 10 lines. Black, covered with iridescent 

 pile, which has a mixture of violet and blue shades ; the meta- 

 thorax sanguineous, truncate, and having a central longitudinal 

 impressed line ; the legs spinose ; the wings dark fuscous ; the

8. FERREOLA FASCIATA. 



Male. Length 5 lines. Black : the metathorax has a central 

 longitudinal impressed line, and is covered with short silvery 

 pubescence ; truncate posteriorly ; wings subhyaline, the neura- 

 tion as in F. distincta ; the second segment of the abdomen has 

 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.

Female. Length 6 lines. Black : a narrow pale testaceous line 

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

 cence ; their base, to the extent of one-third of their length, clear 

 hyaline. Abdomen covered with a violet iridescent pile.
