Male, This species, described very briefly by Loew, is easily 

 distinguished by its uniform black colour, hyaline wings and the 

 palpi tipped with red. The antennae are Tabanus-like in shape, 

 the third joint broad at its base and red in colour, situated on a 

 tubercle formed by the subcallus. The face is concave in the 

 centre, the cheeks swollen and covered with black hairs. Proboscis 

 2 mm. in length. Eyes hairy, ocelli and spines on hind tibiae are 

 present. The species does not appear to have been noticed by 

 any author since Loew described it, aiid though its appearance 

 is totally unlike that of the typical species of Rhinomyza it does 

 not appear to belong to any other genus as yet described. The 

 female mentioned above has not been examined by me. 



The type, a male, came from the Cape of Good Hope. 



EHINOMYZA ZOULOUENSIS, n. sp. 



Type (female) from Zululand (M'fongosi, W. E. Jones). A 

 typical species of this genus, distinguished by the black markings 

 on the first four abdominal segments forming four broken and 

 irregular stripes. Antennae red with long upper branch of third 

 joint. Abdomen and legs yellowish. Wings brown at base with 

 a brown band across wing. Length 15 mm., proboscis barely 

 2 mm. 



Face shining, pale yellow-ochre colour, cheeks with some grey 

 tornentum, very few hairs discernible on face. Beard composed 

 of scanty yellowish hairs. Palpi long, more than half the length 

 of proboscis, the first joint the colour of cheeks, the second reddish 

 yellow with black .short hairs, almost the same width throughout, 

 more than twice as long as the first joint. Antennae reddish yellow, 

 the first two joints paler, the third dusky at its apex, the long 

 upper branch as long as the first division of joint. Forehead same 

 colour as face, shining, a little narrower at vertex, nearly twice 

 as long as it is broad anteriorly. Eyes bare, ocelli distinct on 

 black triangle. Thorax dull yellowish with three mahogany-coloured 

 stripes, some grey tornentum on dorsurn and scattered short 

 yellowish pubescence. Scutellum mahogany coloured, with a. 

 paler border. Abdomen pale yellow on the first two segments, then 

 dull reddish brown, the black marks consist of four spots on the 

 first segment, those at the sides taking up the whole width of 

 segment, inclined inwards from their bases, the two in centre 

 shorter, on the second segment the four spots are united at their 

 bases by a narrow dark band, the two median ones large, irregular 

 in shape, not quite reaching the anterior border of segment, the
