BOMBYLIUS FURIOSUS, Walker (1860). 



A very distinct species on account of the bright orange tufts on the 

 sides of the abdomen. 



Originally described from Port Natal ; there are some males from 

 M'Fongosi, Zululand, December, 1911 (W. E. Jones), from Barberton, 

 Transvaal (H. Edwards), and from Durban, Natal, April (J. H. 

 Bowker). 



BOMBYLIUS ORNATUS, Wiedemauu (1828). 



Easily distinguished by its smaller size and hyaline wings, which 

 have the base oiilv uarroAvlv black. 



V * 



Plettenberg Bay (Cape), June; Potchefstroom, Transvaal (T. 

 Ayres) ; Dunbrody (Cape) (J. A. O'Neil) ; Estcourt, Natal 

 (Haviland). 



BOMBYLIUS RUFIVENTRIS, Macquart (1846). 



Closely allied to the preceding species, but distinguished by the 

 prevalent black hairs on the face, and by the reddish tomentum <>f 

 thorax and abdomen. 



Some specimens of both sexes from M'Fongosi, Zululand, December, 

 1911 (W. E. Jones) ; Durban, Natal (T. D. Butler) ; Lourenco Marques 

 (Mozambique) (T. B. Paulus). Originally described from Port 

 Natal. 



Length of the body 5-7 mm. Previously mistaken by me for 

 ornatus. On the face the black hairs are so prevalent that the cross- 

 baiid of silvery hairs is much less distinct than in ornatus. Thorax 

 and scutellum of male with only a less distinct scaly tomentum of 

 golden colour, while in the female this tomentum is so dense that 

 these parts appear to be entirely golden reddish ; in addition in the 

 female the hairs on the pleurae are yellow, not black. The scaly 

 tomentum of the abdomen is well developed in the male, while in the 

 female it is as dense as that of the thorax. On the wings the discoidal 

 cell is very acute outwards, and therefore the base of the second 

 posterior cell is pointed and often this cell is briefly stalked, while in 

 firnatus the same cell is always sessile and usually broad at base. 



The female of the present species is very like a small Usia in 

 appearance. 



(B) GROUP OF B. MINOR. 



I have placed here a great number of species of medium and often 

 <>f very small size, which were completely unknown to Loew at the
