Halictus albidus, Lepel. 
Halictus albidus, Lepel. Hist. Nat. Hym. ii. (1841) p. 281. 
A solitary male from Pretoria (Déstant) answering entirely 
to Lepeletier’s description. 
Halictus terminalis ?, Smith. 
Halictus terminalis, Smith, Cat. Hym. B. M. i. (1853) p. 54, 2. 
A single female from Durban (4. Foss). 
I am somewhat doubtful about the identification of this. 
The specimen agrees with the type in the British Museum 
collection, but differs from Smith’s description in having the 
antenne entirely black, not ‘‘ rufo-testaceous beneath,” and 
the sides of the anal rima also black, not “ bright ferru- 
ginous.” 
Halictus communis, Smith. 
Halictus communis, Smith, Descr. New Spec. Hym. Brit. Mus. (1879)

Nomia tridentata, Smith, Trans. Ent. Soc. (1875) p. 64.

dall). 
Nomia armatula, Dalla Torre. 
Heme ee Smith (nec Oliy.), Trans. Ent. Soc. (1875) p. 67, pl. i, 
Nomia armatula, Dalla Torre, Cat. Hym. x. (1896) p. 164. 
A single female, Pretoria (Distant). 
Smith described and figured the posterior leg of the male. 
This insect, which I take to be the female of Smith’s species, 
resembles the male (the type of which is in the British Mu- 
seum collection) in size, colour, sculpture, and pubescence, 
differing only in the coxe, femora, and tibiz of the legs being 
entirely black, and only the basal ¢wo joints of the flagellum 
of the antenne being fulvous beneath. 
Nomia crociseformis, sp. 1. 
9. Black, the apical margins of the abdominal segments 
1-4 with broad non-pubescent bands of bluish white above,
