OSMIA, Panzer. 
OSMIA NATALENSIS, sp. nov. 
Q. Length 10°5-11 mm.; robust, pure black, closely and con- 
spicuously punctured ; head broad; face covered with long greyish- 
white hair, vertex with dark fuscous; mandibles broad, black and 
sharply quadridentate ; clypeus truncate, with simple margin, its 
“surface finely rugose, and covered with hair; vertex shining and well 
punctured ; antenn black, the flagellum very short ; mesothorax and 
scutellum very densely punctured, and with thin inconspicuous fuscous 
hair; behind scutellum is a fringe of long white hairs; tubercles and 
pleura with long abundant white hair, slightly creamy on tubercles ; 
tegule black, punctured ; wings strongly dusky, grey, the stigma and 
nervures black; legs with pale hair; hind basitarsi long; spurs 
ferruginous ; abdomen with little hair, shining between the close 
punctures, which are smaller on first two segments than beyond ; hind 
margins of segments with extremely narrow white hair-bands, sixth 
segment pale grey from a covering of appressed hairs ; ventral scopa 
pale red, in the type carrying bright orange pollen (not of the 
Composite). 
Type from Winklespruit, Natal, 2nd January, 1919 (C. N. Barker). 
Also from Stella Bush, 18th October, 1916 (H. W. Bell Marley). 
Related apparently to O. e/izabethe, Brauns, but that has the meso- 
notum with yellowish-red hair.

This has well-developed pulvilli, and is an Osmia; it was a strange 
oversight to fail to see this when describing: The species is valid, and 
related to O. natalensis, but easily separated by the more hairy, more 
glistening, and less densely punctured abdomen, colour of tegule, ete. 
While on this group I take the opportunity to note that the related 
Algerian parasitic genus Perezia, Ferton (Ann. Soc. Ent., France, 
1914), is a homonym of Perezia, Léger -& Duboseq, 1909. — Ferton’s 
genus may take the name /ertonel/a, n.n., type Vertonella maura 
(Ferton).
