S16: Natal Bees 
apically. Mesothorax distinctly margined with pale ochreous hair, 
and post-scutellum densely covered with the same. Plice at base of 
metathorax short and feeble, and the smooth surface beyond not so 
polished as in male. Fourth abdominal segment with much pale hair. 
Hind spur with a few long spines. 
Type (male) from Winklespruit, Natal, 4th January, 1919, three 
specimens (C. N. Barker). Females from Umbilo, 10th February, 
1917 (L. Bevis), and Durban, 7th & 31st July, 1916, and 4th December, 
1918 (C. N. Barker). 
Although there is a marked difference in the base of metathorax, I 
think the sexes are correctly associated, as the venation exactly agrees 
(and differs from other possible candidates for association), and the 
hair on thorax and characters generally are alike. The var. a is from 
Durban. The female is distinguished from other Natal species by the 
smal] size, dark legs and dull mesothorax ; the male by the red tarsi 
and ochreous hair of thorax, combined with a pale-banded clypeus. 
HALICTUS BURNUPI, sp. nov. 
9. Length 5°5 mm.; not very robust; head, mesothorax and 
scutellum very dark olive green; metathorax dull black ; legs black, 
with pale hair; abdomen shining dark brown, without hair-bands, 
the concealed bases of the segments pallid. Mandibles reddish sub- 
apically ; clypeus somewhat shining but not polished, the punctures 
indistinct ; front somewhat shining; antenne black ; thorax small, 
with thin white hair ; area of metathorax appearing broadly semilunar, 
entirely dull and rough, but not plicate; tegule small, rufopiceous ; 
wings dusky-hyaline, stigma and nervures brown; first recurrent 
nervure joining second submarginal cell some distance before its end ; 
outer transversocubital and recurrent weak but distinct; hair of 
abdomen thin and sparse. Microscopical characters: punctures of 
clypeus very sparse, on a minutely wrinkled or tessellate surface ; 
front densely minutely wrinkled, with minute shallow punctures ; 
mesothorax and scutellum minutely tessellate, with sparse very minute 
punctures ; area of metathorax with no sharp rim, its surface extremely 
minutely cancellate, and with weak irregular plice (not noticed under 
a lens); posterior truncation not sharply defined ; tegule impunctate ; 
hind spur with two very large obtuse spines. 
Durban, 24th October, 1918 (C. N. Barker). Known among the 
Natal species by the small size, green mesothorax ; venation and hind 
spur as described. It is referable to the subgenus Chloralictus.
