 a brown spot below each eye ; antennae shorter than the head, yellowish- 

 brown, becoming dark brown at the apex, arista black, the base yellowish, 

 proboscis and palpi brownish-yellow ; body reddish-brown, mesonotum and ! 

 abdomen with a mediodorsal black line, and sometimes with blackish mark-

 long as wide, the third segment in the male bearing a row of black bristles 

 extending from the venter nearly half way to the middle of the dorsum ; 

 wings hyaline, the subcostal and marginal cells, base and usually the very 

 narrow edge of the submarginal cell beyond apex of the marginal about half 

 way to tip of third vein, where it expands and fills the entire apical portion 

 of this cell and encroaches on the first posterior cell, brown, a brown cloud 

 on distal part of anal cell ; apex of fourth vein, not or very slightly 

 approaching toward the third vein ; legs yellow, apices and middle and hind

 last four joints of all the tarsi reddish-brown ; tibite and apices of femora

" Differs from brevis as follows : The spot above centre of front scarcely 

 darker than the reddish-yellow frontal vitta, no black spots on the face, bases 

 of palpi pale yellow, yellow spot on each hypopleura nearly twice as long as 

 wide, brown in marginal cell, not connected with that in apex of the sub- 

 marginal, the latter extending one-third of distance from apex of third vein 

 to apex of second, ovipositor of female greatly flattened, legs yellow. Length, 

 5 to 6-5 mm. Four males and four females." Collected at East London,

NOTE. I have received a co-type of this handsome little fruit-fly from 

 Mr. Lounsbury, and add the following : The eyes dark, the yellow markings 

 on the thorax very bright coloured, scutellum elongate slightly arcuate in 

 front ; the dorsal black stripe down the centre of the thorax broadest behind, 

 nearly wedge shaped, apex of thorax below scutellum black ; abdomen dark 

 reddish-brown, with the centre crossed with a black band or bar that swells 

 <lown on either side, forming an irregular oval black patch merging into the 

 bar.

" Differs from the above description of brevis only as follows : The dark 

 brown spot above centre of front is connected with the upper two spots in 

 each of the orbital rows, no brown spot below each eye, no mediodorsal black 

 line on the abdomen, apical section of fourth vein strongly bisinuous, the 

 -apex strongly approaching towards the third vein, legs yellow, the apices of
