NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 223 



4. Conradtina suspensa, sp. nov. (fig. 1). 



Very distinct from all the other known species on account of the broad fuscous 

 patch on the middle of wings, comprising in a single spot both the cross-veins, as 

 in Lagarosia. 



$. Length of body (with the ovipositor), 10 mm. ; of wing, 8 mm. 



Head reddish yellow, with a broad black patch on each side of the occiput, which 

 shows no distinct lateral swellings. Frons with a dark stripe on each side, which is 

 shining and prominent on the basal half ; the face and the rather narrow jowls are 

 without dark spots. Antennae wholly yellowish, the third joint rounded at tip and 

 a little longer than the face ; arista rather long plumose, the feathering being 

 broader than the breadth of the third antennal joint. Palpi and proboscis dirty 

 yellowish. The cephalic bristles seem to be all of a black colour, but they are in 

 part broken off. Thorax black on the back, with a faint pale pubescence ; humeri 

 pale yellowish ; the sides of back near the suture and on the hind half are partly 

 of a dark reddish colour ; pleurae black, shining, but the whole sternopleura 

 is yellowish. Scutellum triangular, flat above, pale yellowish on the sides and

below, much darker reddish in the middle ; it bears four bristles. All the 

 bristles are black ; sc. long and strong. Mesophragma entirely black, rather 

 shining. Halteres pale yellow. Abdomen quite bjack, even on the venter; 

 ovipositor black, flat, as long as the last two abdominal segments. Legs with 

 all the coxae and the anterior and posterior femora pale yellow ; middle femora 

 mostly dark brown ; all the tibiae dark brown or even blackish, with the tips 

 narrowly reddish ; middle tarsi quite black, the others reddish at base. All the 

 femora are armed on the apical half with two rows of short but strong, black spines, 

 3-4 in each row. Wings (fig. 1) with the normal venation ; the 3rd longitudinal 

 vein is provided with 3-4 bristles only at its extreme base. They are whitish- 

 hyalme, with three fuscous bands, disposed as follows : The first is narrow and 

 extends perpendicularly from the stigma to the end of the anal cell. The second 

 is very broad, shaped as a rounded spot extending from the 3rd vein to the hind border, 

 enclosing the two cross- veins, and joined by a short peduncle to the apical band. 

 This last, or the third, is narrow and regularly curved ; after the end of the 2nd 

 vein it is removed from the costa, which is again reached at the end of the 4th, thus
