NOTES ON THE ETHIOPIAN FRUIT- FLIES — II. 31 



basal spot ; marginal cell with 3 hyaline spots, the first two being larger and more 

 approximated ; submarginal cell with 3 hyaline spots, the largest of which is placed 

 below the first two spots of the marginal cell, forming with them a pyramid, the second 

 is very small, and is placed just after it, and the middle-sized third one is placed 

 at the fore border a little behind the end of the second longitudinal vein ; first 

 basal and first posterior cells in all with 4 hyaline spots, one before and one beyond 

 the small cross-vein, one in middle and one at end, this last being rather small, and 

 therefore the black is not radiating ; discoidal cell with 2 hyaline spots, a middle 

 one of greater size and one placed before the middle of the hind cross-vein ; 2nd 

 posterior cell with 3 elongate hyaline spots, forming 3 indentations ; third posterior 

 and axillary cells with 8-10 hyaline spots, forming a kind of reticulation: 



Type (J, type $, a single couple of specimens from Durban, Umbilo, 21. vi. 1916 

 (L. Bevis). 



Another male specimen from the same locality, but caught 21. ii. 1914, is a little 

 different in the wing pattern, the discoidal spots being much smaller, chiefly that 

 in the middle of the discoidal cell ; the 3 indentations of the 2nd posterior cell 

 are shorter, the last being divided into several smaller spots. In this specimen 

 also all the bristles of the head and body are of a pale yellowish colour. 



3. Euaresta (Pliomelaena) strictifrons, sp. nov. (PI. i, fig. 7). 



Nearly allied to the preceding sj)ecies, but distinguished by the narrower frons 

 and the somewhat different wing pattern. . . 



§. Length of the body, 5 mm. ; of the ovipositor, 1 mm. ; of -the wing, 5 mm. 

 Head and its appendages as in the preceding species, but the frons is much narrower, 

 being narrower than the eye and only twice as long as broad ; the 3 lower or. are 

 black. Thorax black on the disc, reddish on the sides of the back and on the whole 

 of the pleurae ; scutellum black with reddish border ; all the bristles are yellowish ; 

 the pubescence and the dust of the back are not well preserved in the type. Meso- 

 phragma shining black, with faint dust. Knob of the halteres blackish. Abdomen 

 shining black, with black pubescence ; it is more elongate than that of the preceding 

 species, but the ovipositor is shorter and broader. Legs entirely pale yellowish 

 and more slender ; front femora with 3 darkish bristles beneath. Wings like those 

 of brevifrons, but with the following differences : they are distinctly broader, and 

 thus the second longitudinal vein is more divergent ; the costal cell has 2 broad 

 and rounded brown spots ; the basal hyaline spot of the stigma is broader ; the 

 third and smaller hyaline spot of the marginal cell is wanting ; submarginal cell 

 with another hyaline spot at the extreme base ; the middle hyaline spot of the 

 first posterior cell is wanting ; the discoidal cell has a single hyaline spot ; the 

 second posterior cell has likewise 3 hyaline spots, but they are smaller and not 

 like indentations ; third posterior and axillary cells with less numerous and smaller 

 hyaline spots. 



Type $, a single damaged specimen from Durban, Umbilo, 20.xii. 1913 (L. Bevis). 



XXX. Ensina, Robineau-Desvoidy (1830). 



As already stated by Prof. Hendel, the present genus must be extended to embrace 

 other species besides the typical sonchi ; and since the prolongation of the
