XXII.—On South African Bees, chiefly collected in Natal, 
by : 
T. D. A. Cockerell, University of Colorado, 
CERATINA, Latrielle. 
CERATINA VIRIDIS, Guérin. 
2. Doonside, 20th December, 1916 (L. Bevis). Umbilo, 18th 
February, 1917 (lL. Bevis). C. viridis was described from Senegal, 
and I have specimens from Benguela. I am quite unable to separate 
those from Natal, though the wide range is surprising. The abdomen 
in Natal specimensevaries from blue to green. 
CERATINA BRAUNSIANA, Friese. 
2. Krantz Kloof, 2nd October, 1916 (Marley). Agrees with 
specimens from Algoa Bay, received from Dr. Brauns. 
CERATINA MIMULA, Sp. nov. 
@. Length 7°5 mm.; black, with fuliginous wings; clypeus 
normal, with a broad pale yellowish band; anterior femora with a 
short yellow line in front, and their tibiz with a similar line at base ; 
hind tibie with abundant long hair on inner side; abdomen densely 
punctured, the segments at sides fringed with widely spaced yellowish 
spine-like bristles; third ventral segment with a very conspicuous 
transverse patch of white tomentum. 
Krantz Kloof, 30th October, 1916 (Marley). Very close to C. 
geigerie, Ckll., but differing by the entirely black tubercles and 
darker, more violaceous wings. C. geigerie is from Benguela. The 
clypeus has a feeble median sulcus, not distinct and conspicuous as in 
C. sulcata, Friese. 
CERATINA SPECULIFRONS, sp. nov. 
2. Length 10-105 mm.; black, with fuliginous wings; no pale 
markings on head, thorax or abdomen; no abdominal hair-bands ; 
anterior tibie with an ivory-white stripe on outer side, extending from 
base to a little beyond middle ; hind tibie angulate externally beyond
