only 2 scutellar bristles, the lower angle of the anal cell acute, and the 6th longitu- 

 dinal vein longer ; besides, the wing pattern is different, having only 3 rays produced 

 to the hind border of the wing. 



Described from the Cape and recorded from Rhodesia. 



5. Trypanea aira, Walker (1849). 



Described from the Congo and not recorded subsequently. It seems to have a 

 wing pattern more reduced than that of the preceding species, and thus more 

 approaching to that of the two following. 



6. Trypanea peregrina, Adams, Kans. Univ. Sci. Bull, hi, 1905, p. 170. 

 Described from Rhodesia, Salisbury, and apparently closely allied to the following 



new species. 



7. Trypanea urophora, sp. nov. (PI. i, fig. 11). 



An elegant little species, distinguished by its very long and cylindrical ovipositor, 

 and by its wing pattern, which is much like a diffuse reticulation of the Euribia 

 type, but covering only the apical half of the wings. It is closely allied to the 

 European species mamulae and gnaphalii, differing in the less developed dark 

 pattern of the discoidal cell, which in the female is entirely hyaline ; but it is possibly, 

 like peregrina, only a form of those. 



<J$. Length of the body, 2 '2-2 "8 mm. ; of the ovipositor, 1.6 mm. ; of the wing, 

 2 '4-3 mm. Head broad, occiput black, grey-dusted ; frons flattened, not prominent, 

 broader than the eye, only one and a half times as long as broad, opaque yellowish, 

 with whitish lunula, broad whitish orbits and whitish ocellar triangle, in which 

 there is a dark dot ; face short, pale yellowish ; cheeks and jowls narrow, whitish, 

 the latter immaculate. Antennae reddish yellow, as long as the face, 3rd joint 

 about twice as long as the not projecting second joint, broad and rounded at tip ; 

 arista short, dark brownish, bare. Palpi and proboscis pale yellowish, the latter 

 long and geniculate, but with the recurrent flaps shorter than the basal part. The 

 bristles of the hind border are whitish and thickened ; those of the frons are dark 

 brownish ; the 2 lower or. and the oc. are strong. Thorax, scutellum and mesophragma 

 black, clothed with dense cinereous dust, chaetotaxy complete, except the scp. 

 which are, as usual, rudimentary ; all the bristles are pale yellowish, those of the 

 basal scutellar pair being long and inserted on rather broad dark dots ; the apical 

 pair is wanting. Halteres whitish. Abdomen coloured like the thorax, with rather 

 long pale yellowish pubescence and with some short bristles of the same colour 

 at end ; ovipositor shining black, cylindrical and not much swollen at base ; 

 clothed with long scattered brownish hairs. Legs entirely yellowish ; front 

 femora with 3-5 yellowish or brownish bristles beneath ; hind tibiae with no 

 distinct row. Wings elongate, with a small costal bristle ; 2nd longitudinal vein 

 long, nearer to the end of the 3rd than to that of the first ; third vein 

 bare ; 2nd, 3rd and 4th veins straight and slightly diverging towards the end ; 

 hind cross-vein arched outwardly and only a little longer than its distance from 

 the small cross-vein ; lower angle of the anal cell acute but not much produced ; 

 6th vein rather short and not prolonged into spurious continuation. The wings are
