Hymenoptera from the Transvaal. 53 
along the apical margins of the abdominal segments with 
somewhat sparse yellowish-white pubescence ; the head above, 
the thorax, and the basal halves of all the abdominal segments 
closely and not very finely punctured, opaque, the apical 
halves of the abdominal segments nearly smooth, very minutely 
transversely rugulose. Head from the front orbicular, the 
vertex rounded, transverse, and short; thorax short and 
massive; scutellum, postscutellum, and median segment 
roundly and steeply sloped, the postscutellum without a 
mucro. Wings hyaline, nervures and tegule reddish yellow. 
Legs: the femora of the posterior pair of legs immensely 
swollen, somewhat flat; the tibie very broad, with the inner 
angle at apex produced and acute. Abdomen massive, some- 
what elongate and oval.

Two males from Fort Johnston, Nyasaland (Rendall). 
I am a little doubtful as to whether these are identical with 
Walker’s insect, but they so closely resemble the type of 
N. zonaria in the British Museum that I prefer to consider 
them merely a variety of that species. They differ in having 
the inner angle of the enlarged and flattened tibize of the 
posterior pair of legs acutely but shortly produced, and not 
with a long curved spine.
