49 New Records of Natal Bees 
smooth median line on clypeus less distinct ; vertex with black hair ; 
mesothorax and scutellum with a strong admixture of black hair ; 
wings distinctly brownish; sixth abdominal segment with hair all 
black ; ventral secopa pure white at sides, fulvous in middle, black at 
extreme apex. 
Umbilo, 10th Oct., 1915 (L. Bevis; 1708). 
The following key separates this from several rather similar species : 
Abdomen with fulvous hair-bands; ventral scopa mainly red, 
but white at base and black at apex ... . ekwivella, Ckll. 
(Benguella). 
Abdomen without fulvous hair-bands ... . 1. 
1. Hair on scutellum all, or practically all, black ; ventral scopa 
coloured as in ekwivella . . . . caricina, Ckll. 
Hair on scutellum all or partly pale... . 2. 
2. Hair on scutellum entirely pale; hair around ocelli tinged 
with fulvous .. . . venusta, Smith. 
Hair on scutellum partly black... . 3. 
3. Length about 8 mm.; disc of mesothorax glistening between 
the punctures . . . . gratiosa, Gerst. (Transvaal). 
f Length about 11 mm.; disc of mesothorax dull 
venustella, Ckll. 
My . gratiosa was determined by Strand, and represents that 
species as understood at the Berlin Museum. It was collected by 
F. Wilms at Lydenburg, Johannesburg. 
HertADEs BEVISI, Ckll., variety a. 
¢. Length 5 mm., anterior wing 4mm.; black, coarsely punctured, 
with white hair, on abdomen only forming distinct bands at sides of 
first and second segments; axillar spines well developed. Differs 
from typical bevisi by the brownish wings and shorter second sub- 
marginal cell ; it may possibly prove to be a distinct species. 
Umbilo, 16th March, 1915 (L. Bevis; 1531). 
HerRIADES CHLOROPS, Sp. nov. 
g. Like H. bevisi variety a, with brownish wings and relatively 
short second submarginal cell, but distinct hair-bands only at sides of 
first abdominal segment, and flagellum long and slender (about 2-4 mm. 
long), distinctly crenulate, the middle joints about 190 microns long.
