and metathorax with dark red hair; pleura with black hair ; hair of 
legs black ; first abdominal segment with rather bright red hair, but 
appressed white hair at sides and along posterior margin ; remaining 
segments appearing bluish-grey with narrow pale bands, the bluish 
effect due to a mixture of black and white ; ventral scopa black, the 
basal middle creamy-white; facial quadrangle about square; mandibles 
massive, broad, with a deep notch separating the apical teeth ; clypeus 
much more than twice as broad as high, coarsely and very conspicuously 
punctured, but not keeled, the lower edge straight except for a slight 
crenulation ; mesothorax dull, very densely rugosopunctate ; tegule 
piceous, with a broad fulvous border, finely punctured ; wings hyaline 
faintly dusky, apical margin not darkened; nervures black ; hind 
basitarsus not very broad. 
gd. Length about 16 mm.; like the female in general appearance, 
but narrower; mandibles dark red, very broad, and elbowed in 
middie; cheeks with dense pure white hair beneath; face and front 
with pale yellow silky hair; vertex with dark fuscous hair ; flagellum 
slender, not enlarged at end; first abdominal segment with less red 
hair; anterior cox with very long curved black spines; a large tuft 
of pure white hair in front of base of each anterior femur; legs 
slightly rufescent, the anterior tibiz strongly so on inner side; 
anterior femora with a line of pure white tomentum beneath ; anterior 
tarsi broadened, cream-colour except the unmodified apical joint, with 
a fringe of long white hair, lined with blackish within; the second 
joint with a dark spot beneath, and the basitarsus with a dark anterior 
callosity, covered with short stiff black hair; the second and third 
joints with short grey hair, more or less tipped with fulvous, on 
anterior side ; claws bifid at end; sixth abdominal segment broadly 
truncate but the margin strongly denticulate ; at each extreme side 
of the segment is a short but stout thorn-like tooth ; seventh segment 
with a short triangular median tooth. 
Type from Durban (E. C. Chubb). Also another female with the 
same data, and males from Durban, 9th March, 1918 (C. N. Barker), 
and Umbilo, 7th February, 1917 (L. Bevis). I have also received 
both sexes from the Cape Town Museum, collected at Mfongosi, 
Zululand (W. EK. Jones). I was surprised to find no description of 
this large and handsome insect. It looks like If. fimbriata cerulea 
(Friese), but the abdomen of the female is not at all metallic, and 
there are many other differences. In Friese’s key it seems to run to 
the /aminata group, and in the form of the clypeus (though not of the 
mandibles) there is a certain approximation to the Humegachile group. 
The structure of the male abdomen indicates affinity with cerulea.
