Bile Natal Bees 
schultzet seems not to have a specially lengthened tongue, and neither 
it nor Nesohalictus have sub-apical ventral spines on the abdomen, 
such as I find in the Natal males. By reason of the long slender 
tongue, these insects also approach Thrinchostoma, and there are 
other African Halicti (7. patricius, Strand ; H. flavofasciatus, Friese) 
which more or less resemble that genus. 
T should be inclined to regard the three Natal species as constituting 
a distinct genus, very close to Mesohalictus, or even as members of 
that genus; but Pate/lapis connects them with Halictws, and on the 
basis of its leading character, should include them. I therefore 
describe them under //alictus, leaving a more precise classification to 
the future, when more material shall have accumulated. They are 
H. harveyi, H. trimema and H. bowkeri. 
Hauicrus HARVEY], Sp. nov. 
g. Length about 7 mm.; black, robust for a male, with very 
seanty dull white hair, partly dark fuscous on mesothorax and 
scutellum; malar space linear; clypeus prominent, with shallow 
punctures running more or less in grooves; tongue long, apically 
linear ; front dull, but vertex shining; antenne rather long and 
thick, the flagellum moniliform, its apical part very obscurely brownish 
beneath ; mesothorax and scutellum dull, with fine punctures ; area 
of metathorax sharply defined, finely wrinkled; at each side of the 
basal area posteriorly is a shining space regularly crossed by plice ; 
posterior truncation sharply defined at sides; tegule chestnut-red, 
black at base; wings dusky hyaline, nervures and stigma piceous ; 
first recurrent nervure meeting second transversocubital ; legs black, 
with the knees, the anterior tibiz in front, all the tibize at apex, .and 
all the tarsi, bright chestnut-red ; hind spurs not dentate; abdomen 
broad, shining, with excessively minute but very numerous punctures ; 
no distinct hair-bands; a broad rounded apical plate, and short 
lateral sub-apical ventral teeth. 
Durban, 9th May, 1918 (C. N. Barker). Two specimens. A 
number of years ago I named a series of Australian /Halicti after 
early explorers and noted scientific men of that country. I will 
follow a similar method in providing names for the 8S. African species. 
HALICrUS TRIMENI, sp. nov. 
¢ (Type). Length 8-8°3 mm. ; black, robust, with rather short 
thick antennz, the flagellum faintly brown beneath ; tongue about 
or nearly as long as head, its apical half linear ; mandibles dark
