Museum ; one female from Salisbury, S. Rhodesia (R. W. 
Tucker), i Cape Coll. Museum; one female from Pretoria 
(Miss J. Brincker), 1915, 125; and females from Estcourt, 
Natal, Sept. and Oct. 1896 (G. A. K. Marshall), 1908, 17 ; 
all in Brit. Mus. Coll., except where otherwise specified. 
These specimens from a rather wide range of localities 
appear to be all identical, and agree with the description of 
Bezzi’s species. He gives the size as 15-18 mm., describing 
one or more males from Somaliland. These range in size from 
14 to 20 mm. in the males and in the females from 15 to 
17 mm. 
A species distinguished by the white short pubescence on 
abdomen and legs, aud by the median black stripe and white 
bristles on the abdomen. The moustache white with black 
hairs intermixed varies somewhat—in the females chiefly 
white, in the males the black hairs preponderate. The 
farehead with black and white bristly hairs, and the curled- 
over bristles black and white. Mane with long outstanding 
bristles and shorter black hairs, posteriorly forming a white 
mane continued on to the scutellum, which is armed with 
six black bristles. The fore and middle tibie are black 
with a red stripe, occasionally present on the hind pair, 
bristles on legs are chiefly white. Genitalia of male stout, 
long, club-shaped, with a fine yellow process produced 
below, reaching the under lamelle which are stout and 
short ; all a chestnut colour covered with white pubescence. 
Ovipositor of females short, black. 
Bezzi speaks of it as a fine distinct species, distinct from 
the three Loew species, viz., spiniventris, ustulatus, and 
pulcher, and from my species albofasciatus. From this 
latter it is distinguished by the much longer genitalia and 
by the white bristles on the legs. 
Dysmachus natalensis, sp. n. 
Type (male), type (female), and one other male, all from 
Willow Grange, Natal (W. C. Wroughton). 
One male from 8. Africa (Distant Coll.). 
A small greyish species in the same group as Dysmachus 
wroughtoni, sp.n. The black mane has a few long white 
bristly hairs on each side on the posterior half of thorax. 
' Moustache black above, yellow below. Legs blackish, only 
the extreme base of tibie red. Genitalia of male large, 
stout.
