Wasps of the Genus Tachytes. 33 
with golden pubescence; eighth sternite deeply and rather 
narrowly emarginate, the angles produced. Second and 
third joints of the labial palpi subequal, rather short. 
Hab. Nyasaland, Mlanje (S. A. Neave), January to April;

(S. A. Neave), April. 
This is a smaller species than separabilis or hamiltoni, aud 
may also be distinguished in the male sex by the seventh 
tergite which is rounded, not truncate, and by the more 
narrowly emarginate eighth sternite. The female may be 
distinguished from separadilis by the much more pointed 
pygidial area. The galea is also much shorter and broader 
than in either of the above-mentioned species, being no 
longer than the scape.

9. Clypeus broadly rounded at the apex ; vertex not 
distinctly punctured. Eyes separated on the vertex by a 
distance not quite equal to the length of the second joint of 
the flagellum. Basal joint of the fore tarsus with five spines. 
Second sternite subopaque, very minutely and closely 
punctured, with a smooth area on the middle of the apical 
margin. In addition to the apical fasciz the dorsal seg- 
ments are thinly clothed with very short dull golden pubes- 
cence ; the pygidial area is rounded at the apex. Third 
cubital cell shorter than the second on the cubitus by about 
one-quarter. 
36. Seventh tergite rather narrowly truncate at the apex; 
eighth ventral segment truncate at the apex, the angles not 
produced. ‘The pubescence on the abdomen is paler than 
in the female; and the eyes are very close together on the 
vertex, separated by about the length of the first joint of 
the flagellum.
