the posterior borders of the second and third appear reddish ; 
each segment is armed with very stout black bristles at the 
sides ; the pubescence on dorsum is chiefly white, longer and 
thicker on the first two segments ; short white bristles are 
present on the sides of abdomen and a few below on thie 
underside, which is also covered with white pubescence. 
Genitalia blackish, stout, with chiefly. white hairs, club- 
shaped. Legs blackish, only the knees and base of fore 
tibize dull testaceous, the white pubescence is long on the 
coxe, short but fairly thick elsewhere, long on the underside 
of the femora and tibiz ; white bristles are visible on the 
middle of hind femora, two or three in number, on the 
middle tibiz, and especially on the anterior pair w here they 
are long and stout, and are contifucd on to the tarsi in both 
pairs, elsewhere the bristles are black. Wings clear, uni- 
formly greyish. 
Female identical. Moustache is yellower on the upper part 
and largely predominates, not being bordered by black hairs. 
Abdomen not so strongly armed with bristles, the white ones 
predominate. Ovipositor black and shining, short with a 
few yellowish hairs at apex. Legs with many more white 
bristles on the hind femora and middle pair, but none on

Dysmachus similis, sp. nu. 
Type (male), type (female), from Bloksberg, Johannesburg 
(C. H. Pead), 1907, 250 ; and another female from Bar- 
berton, Transvaal (H. Kdwards), April 1911, in Cape Coll. 
Very similar to D. wroughtoni, sp. u., but distinguished 
from it by the shorter genitalia of male and by the ‘bristles 
on the legs in the female being chiefly white. 
Distinguished from D. natalensis, sp. n., likewise by the 
genitalia and by the long numerous black bristles on the 
scutellum. 
It is very nearly allied to D. montanus, sp. n., from which 
it differs in the following particulars :— 
Male.—Moustache is large, composed of black and white 
bristles intermingled, a few yellowish hairs are also visible. 
The front two joints of antenne are armed with very strong 
black bristly hairs on the underside, with a few short white 
ones on the upperside. The curved bristles are very long, 
black and yellow. The mane has dull yellowish. hairs 
bordering the thick black short ones, and there are many
