3. So similar to C. durbanensis that I at first thought it 
identical, but readily distinguished by the very strong transverse 
keel on the metathoracic enclosure, the clearer (yellower) hair of 
thorax above, and the broader abdominal hair-bands. The ventral 
abdominal segments are fringed with very abundant and long hair, 
whereas in C’. durbanensis they have dense short even fringes.

COLLETES SEMINITENS, sp. Nov. 
2. Length about 9 mm.; black, mandibles with a red band, tarsi 
red only at apex ; hair of head and thorax pale ochreous, dorsally 
ferruginous mixed with fuscous ; clypeus densely punctured ; labrum 
smooth, without ridges; malar space very short, at least twice as 
broad as long; flagellum faintly reddish beneath, the last joint 
distinctly so; mesothorax and scutellum dull, the latter with a 
smooth median line; area of metathorax above reticulate, below 
smooth, with a moderate transverse keel; tegule rufous; wings 
brownish-hyaline, nervures fuscous ; middle femora with a prominent 
sub-basal tooth beneath ; legs with pale ochreous hair, middle and 
hind basitarsi with a brilliant copper-red apical brush ; abdomen 
thinly hairy, with pale hair-bands ; first segment polished, with very 
minute inconspicuous punctures, more distinct at the sides ; second 
segment extremely finely and densely punctured. 
Durban, Natal, 11th March, 1917 (E. C. Chubb). 
Possibly the female of C. durbanensis, but the base of metathorax 
differs, and the first abdominal segment is remarkably smooth and 
feebly punctured in the middle. For the present they must be 
regarded as distinct.
