forming a hyaline band, which is as broad as the fuscous band itself. This apical 

 hyaline part is distinctly whitish. There is no trace of a dark streak across the 

 middle of the last portion of the 4th vein. 



Type $, a single, rather old specimen from the Congo, in the writer's collection. 

 II. Carpophthoromyia, Austen, 1910. 



This genus was erected by Austen* on the type-species vittata, Fabricius and Loew, 

 uniting with it also grata, Wiedemann and Loew, scutellata and tritea, Walker, and the 

 two new species formosula and pulchella ; it was distinguished from Ceratitis by its 

 general facies, the flat and triangular scutellum and the tubular ovipositor. In 

 1913*}* I took it as the 5th section of Ceratitis, thus adding to it the species which 

 are now placed in the new genus Trirhithrum. In 1914J Hendel (who at first § 

 had accepted it in the foregoing sense) restricted it to the two species scutellata and 

 tritea, with the main characters of the colour of body, number of i. or., pattern of 

 wings and shape of the cross-veins. 



I have followed here these views of Hendel, but including in the genus also the 

 type species vittata, which has the hind cross- vein not Ceratitis-like and has not even 

 a typical wing pattern. If this species is not congeneric with the others, the name 

 Carpophthoromyia must be used exclusively for it, and a new generic name is 

 necessary for scutellata and tritea. The genus seems to be an exclusively Ethiopian 

 one ; Prof, de Meijere has recently (1914) described a C. tomentosa from Java, which 

 however seems to belong to Carpophihorella, Hendel. For the three species grata, 

 formosula and pulchella, which all agree in wing pattern and have a Ceratitis-like 

 hind cross- vein, but have all a flat scutellum, a new genus is necessary ; but I have 

 not yet seen these species in nature. 



The species provisionally placed here can be distinguished as follows : — 



1(8). Second longitudinal vein rather straight ; base of wing wholly infuscated, 

 without streaks ; scutellum flat above and white or pale yellow in colour ; 

 abdomen destitute of whitish transverse bands. 



2(3). Wings without hyaline indentations at fore border and with the ^-shaped 

 band united with the fuscous of the base in the 3rd posterior cell ; scutellum 

 with brown tip ... . . . . . . . . . . vittata, Fabr. 



3(2). Wings at fore border with a broad triangular hyaline indentation near the 

 stigma ; the inner branch of the A _sna P e d band is separated from the 

 fuscous of the base. 



4(5). Scutellum entirely yellow ; abdomen ferruginous towards the base ; femora 

 tawny ; costal cell partly hyaline . . . . . . . . scutellata, Walk. 



5(4). Scutellum on its posterior margin with three black spots, which are not visible 

 from above ; abdomen entirely black ; femora mostly black ; costal cell 

 wholly infuscated.
