80 H. C. EEFLATOUN. 



inconspicuous pubescence on the upper part only. Antennae dull 

 orange, but darkened about the base and often above the third 

 joint; there are some tiny yellow bristles on the basal joints and 

 two long and four or five much smaller black bristles on the 

 second joint near the tip above; arista dull orange long and bare. 



Thorax and scutellum all shining aeneous, clothed with rather 

 short, but dense, tawny pubescence; thorax nearly always with in- 

 dications of light grey stripes, which never quite reach the lower 

 margin. 



Abdomen entirely the same unicolorous shining aeneous, neat in 

 shape and gradually decreasing in width from the base of the 

 second segment to the end. Pubescence more or less tawny, rang- 

 ing from all brownish-tawny to nearly all pale yellow, but usually 

 brownish-tawny at the base. Venter shining black, with dull 

 yellowish-grey hind margins and pale yellow pubescence, but on the 

 disc of the fourth segment the pubescence is black and on the hind 

 margin there are two tufts of black bristles which overhang the 

 genitalia. Hypopygium rather large but not seen from above, and 

 almost symmetrical. 



Legs black, but the knees are rather broadly yellow including 

 almost half of the anterior and a third of the hind tibiae; anterior 

 tarsi orange at the base up to almost the end of the basal joint; 

 front coxae orange at the tip. Hind femora moderate, and but little 

 1 bicker than the others. Pubescence all moderate in length ami 

 fairly abundant, pale, except for a few bristly hairs beneath the 

 hind femora near the tip, and a few tiny bristles on the dark 

 tips of the anterior tibiae and a part of the fringe inside the hind 

 tibiae. 



Wings slightly tinged with brown, yellowish about the base, 

 with a fairly long and rather conspicuous stigma, which is dark at 

 the base; vena spuria hardly perceptible; the veinlets after cells 

 Rl and R5 both turn upwards, especially the first; the basal por- 

 tion of Radius 2 + 3 bears bristles. Pquamulas large, whitish-yellow 

 with fringes of the same colour. Halteres yellow. 



Female: — Very similar to the male. Frons at the vertex rather 

 narrow and scarcely widening until near the antennae, shining 

 black above and on the puffed out occiput, but brownish and 

 coarsely punctate and dull in the middle; shining black again 

 above the antennae, with a narrow luteous front margin ; it:- 

 pubescence is brownish-yellow at the vertex, then black, then 

 luteous with hairs turned backwards, ending with pale yellow 

 hairs pointing f - ward. The pubescence of the eyes, which is still 

 more limited than in the male is hardly perceptible. The five dull 

 grey stripes on the thorax are much more distinct, and instead of
