Type <5 , a single specimen from Durban, 1902 (F. Muir). 



121. Eumerus scaber, sp. n. 



<S . Length of the body 8 mm. 



A dark purplish, very deeply punctate species, which is closely 

 allied to the following, but has a narrower yellow hind border to 

 the scutellum and less distinct abdominal lunulae. 



Head purplish black, with the occipital border strongly produced 

 above and clothed with short black hair ; posterior orbits silvery- 

 white pollinose below and clothed with white hair ; vertical triangle 

 narrow and elongate, shining black, clothed with short black hair, 

 but its anterior extremity whitish pollinose and pale- haired ; front 

 ocellus occupying a forward position, the ocellar triangle not being 

 equilateral ; frontal triangle very small, shining bluish, with a small 

 median depression, almost bare ; face thinly pollinose and sparsely 

 clothed with white hair ; eyes almost bare, in contact for a distance 

 a little longer than the frontal triangle ; antennae short, black, the 

 third joint rounded. Thorax purplish black, very strongly punctate 

 and therefore but little shining, almost bare, its yellowish dust 

 distinct only on the sides and behind ; pleurae with white hairs ; no 

 distinct longitudinal stripes on the back. Scutellum like the thorax, 

 its hind border not sharply produced, narrowly yellow and minutely 

 granulate. Squamulse pale yellowish like the halteres. Abdomen 

 as broad as the thorax and similarly punctate, rather short and of 

 the same colour ; on the sides it bears a white pubescence ; the 

 lunulae are scarcely distinguishable, on the second and third segments 

 they are indicated only by a rather deep furrow, which is whitish 

 pollinose. Genitalia reddish, very much developed, projecting as a 

 yellow tubercle, fringed with hair on each side, towards the middle 

 of the belly. Legs short, shining black, with very short whitish 

 pubescence ; front coxae dark brown ; trochanters, knees, and all the 

 tarsi yellow ; hind femora thickened, but without apophysis below 

 at the tip, provided only with two rows of short spines, the external 

 more developed ; hind tibiae clothed with short hair like the tarsi. 

 Wings greyish hyaline, with dark stigma, and distinctly infuscated 

 in the middle below the stigma to the fourth vein and from the 

 praef urea to the end of the second vein ; veins black ; vena spuria 

 quite distinct ; apical cross-vein with two stumps ; inferior angle 

 of the discal cell with the rudiment of a stump.
