BOMBYLIUS MOLLIS, sp. 11OV., . 



Very distinct from all tlie other species of the present group on 

 account of the short hairs of the occiput and of the peculiar shape of 

 the second submarginal cell. 



Type rf , a specimen from Salisbury (South Rhodesia), June, lit 1:5 ; 

 another badlv preserved male specimen from Barberton, Transvaal 

 (H. Edwards J. 



The present species is closely allied to the East African nuithoci'i* 

 Jaeuu. (appendiculatus, "Bezzi) and cri/thrncerus, Bezzi (rufoantenuatus, 

 Beck). Length of body, 10 mm. ; of proboscis, 6 mm. Eyes con- 

 tiguous for a distance a little longer than the vertical triangle. Head 

 black ; vertical and frontal triangles black- haired, this last with some 

 shorter yellow hairs on the sides. Face with dense yellow hairs, only 

 beneath with a few black ones ; occiput with short yellow hairs ; the 

 dense hairs of the underside of the head are more pale-coloured. The 

 two basal joints of the antennae are wholly black and black-haired, 

 the third is elongate and black, probosis entirely black ; palpi black, 

 thin. Thorax and scutellum deep black, clothed with equal and 

 entirely yellowish hairs, without any black hairs even on the pleurae ; 

 there are no distinct bristles. Squamae brown, halteres with whitish 

 knob. Abdomen entirely deep black, without bristles, clothed with 

 equal yellowish hairs like those on the thorax, but on the sides of the 

 2nd, 3rd and 4th segments there are tufts of black hairs. Legs 

 yellow with black coxae, trochanters and tarsi ; but the praetarsi are 

 yellow ; spines of the hind femora black. 



Wings greyish, distinctly but very faintly infuscated at base to the 

 second basal cell and to the discal cross-vein ; comb very small, black ; 

 alula brownish, with whitish fringe behind ; veins entirely black ; 

 marginal cell rather broad in the last part ; first posterior cell very 

 acute outwardly and briefly stalked ; discal cross-vein a little before 

 the middle of the discoidal cell ; the cross-vein dividing the discoidal 

 cell from the second posterior cell is very short, and therefore the 

 discoidal cell is rather acute outwardlv. 



BOMBYLIUS BISJUNCTUS, Bezzi. 



Near B. mollis, but very distinct from it and from all the other 

 species here recorded on account of the separated eyes of the male. 



The species seems to be widely spread throughout the whole 

 Ethiopian region, from Abyssinia to Natal ; there is a male specimen 

 from Salisbury, April 24th, 1917.
