Hemiblossia kalaharica Kraepelin, 1908. Denk. med. nat. Gesell. Jena, xm, 
p. 279. 
The type is a female from Khakhea in the Kalahari. 
Hemiblossia idioceras Hewitt, 1917. Ann. Natal Mus. 111. p. 687, fig. 1 a-c. 
This is based on an adult male from Kimberley. The species seems well 
separated from O’neili in the characters of the flagellum, and it is of interest 
to note that both forms have been taken at Kimberley. 
Mr Claude Fuller has taken this species at Pienaar’s Riv. Transvaal: it 
occurred in numbers within the nest of a Eutermes. Mr J. H. Power also 
found adult males in a termites’ nest at Kimberley, Nov. 1918. 
Key to the species of Hemiblossia Kraepelin. 
1. Dorsal margin of flagellum rather strongly curved, though not 
quite semicircular, and at its distal end is an independent process which 
is slender, curved and hairy: the distal margin of the flagellum is some- 
what flattened out, but not into a distinct foliaceous appendage. 
H. O’neili Purcell. 
2. Dorsal margin of flagellum lightly curved, distally with an acutely 
pointed termination : distal margin of flagellum flattened out on the side 
adjacent to the chelicera into a foliaceous extension the margins of which 
are fringed with hairs. H. idioceras Hewitt.

Key to the species of Melanoblossia Purcell. 
1. “ Flagellum ” inconspicuous, being a straight hairy rod, like the 
setae immediately below it. Head-plate moderately convex, with 
notched setae of varying length, but not densely clothed with minute 
cylindrical bristles. Six small teeth in the single series of the upper jaw. 
Second abdominal sternite with two pairs of long narrow pointed fleshy 
hairs. M. braunsi Purcell. 
2. “ Flagellum” similar, but much larger and more conspicuous. 
Head-plate strongly convex, the posterior surface rising vertically, the 
surfaces thickly covered with very short and numerous blackish brown 
cylindrical or pointed bristles. Four small recurved teeth in the single 
series of the upper jaw. Second abdominal sternite with 8-12 pairs of 
filiform fleshy hairs. M. globiceps Purcell.
