112 SYRPIIIDJE. 



with minute, short, whitish hair; antennae reddish yellow, the 

 third joint rather broad, hatchet-like, with the upper border 

 darkened throughout its whole length ; arista inserted near the 

 base, black and bare ; opening of buccal cavity rather broad, but 

 short and almost circular. Thorax shining black, somewhat 

 purplish in the male, finely punctate, clothed in the male with 

 dense and long silvery hair as in panics, and with similar but 

 sparser hair on the pleurae; in the female the thorax is only 

 thinly covered with short hair, and is adorned with two distant 

 white stripes on the fore part. Squarnulse and halteres whitish, 

 those of the male pure white, the squamulse white - fringed. 

 Scutellum shining black, bluish in the male, clothed with erect 

 grey hair, the hind border broad, elevated, and bearing very long 

 black spines, less numerous but stronger than in Paragus serratus. 

 Abdomen as broad as the thorax, with parallel sides, black, but in 

 the male at the base with a bluish and at the tip with a purplish 

 sheen ; the white lunulae of the second to the fourth segments are 

 well marked, but small, very oblique, and widely separated in the 

 middle ; hair very short, only at base long and whitish : genitalia 

 of male of the type of those of panics, but not so prominent. 

 Legs shining black, with white hair ; all the tibiae at base and the 

 tarsi pale yellow; hind tarsi strong, broad, infuscated, with a 

 yellowish ring at the end of each joint ; hind femora simple, not 

 thickened, bearing only a few strong bristles below near the tip ; 

 hind tibiae strong, club-shaped, those of male with distinct but not 

 dense silvery pubescence, which is wanting on the proximal two- 

 thirds of the first basal joint. Wings entirely hyaline, strongly 

 iridescent, with black veins, but less distinct vena spuria ; stigma 

 hardly infuscated at base ; the two outward bends of the apical 

 cross-vein each bear an appendix. 



Type d and type $ from Salisbury, Mashonaland (G-. A. K. 

 Marshall). The female can scarcely be distinguished from that 

 of preceding species, except by its smaller size and darker wings. 



119. Eumerus maculipennis, sp. n. 



$ . Length of the body 5'5 to 6 mm. 



Allied to the two preceding species, but at once distinguished by 

 the yellow spots on the second abdominal segment and the infus- 

 cations of the wings. 



As I have seen only females, which are very like those of 

 serratus, I will here simply state the differences. The size is a 

 little larger; the scutellar spines are less prominent; the second 

 abdominal segment, instead of the usual lunules, bears on each 

 side a broad yellow spot, which forms a transverse band, interrupted 

 in the middle and not reaching the sides. Wings with yellow 

 stigma and distinct vena spuria ; the infuscations are on the small 

 cross-vein, at the prsefurca, and on the two apical cross-veins. 



Type $ and two additional specimens from Oshogbo, S. Nigeria, 

 x.-xii. 1910 (Dr. T. F. G. Mayer}.
