by 7’. D. A. Cockerell. 315 
segments broadly clothed with grey hair, third with a hair-band in 
sub-apical depression, fourth and fifth with sub-apical bands; no 
sub-apical ventral spines. 
2. Similar, but more robust, with the mesothorax dullish, the 
head broader, mandibles dark, the short flagellum red only apically 
beneath. The tarsi are reddish, and the hind spur has five strong 
spines. ‘The second and third abdominal segments have dense white 
basal bands. Superficially, this is very like H. bowkeri, but is easily 
separated by the dise of scutellum shining (dull in bowkeri).  H. 
diversus, also from Natal, has the hind spur with three teeth. Male 
diversus has a yellow apical band on clypeus. 
Type (male) from Durban, 8th October, 1916 (H. W. Bell Marley). 
Females; Umbilo, 14th February, 1917 (L. Bevis), Krantz Kloof, 
23rd July, 1916 (H.W. Bell Marley). This is a true Halictus, but 
resembles the Patel/apis-like series in having the male clypeus black 
without a yellow band. 
Haticrus LAYARDI, sp. nov.

and lower part of mesopleura; all the tarsi, and anterior tibie in 
front, clear ferruginous ; apical band on clypeus, labrum and stripe on

very fine punctures, a couple of thin oblique patches of pubescence 
anteriorly (the same in female); scutellum bigibbous, the bosses more 
or less shining ; area of metathorax polished and shining, with well- 
separated plicew, at sides and posteriorly becoming oblique; sides of 
metathorax with oblique strie ; posterior truncation ill-defined ; tegule 
rufous with black base; wings hyaline, slightly dusky, nervures and 
stigma rather dark rufous; first recurrent nervure meeting second 
transversocubital ; third submarginal cell short, no longer than high ;

3 with continuous bands of greyish tomentum ; a fairly large rounded 
apical plate, but no sub-apical ventral spines. 
@. Size and appearance of the male, but with the usual short 
antenne, the flagellum rufous beneath or (var. a) black, faintly rufous
