A female collected by W. E. Jones at Mfongosi, Zululand (South 
African Museum), agrees in the character of the wings with 
nomieformis, and is placed as such in the table above. Yet it is by 
no means certain that the differences observed may not be ascribed 
to variation, and Mr. Barker notes on his Malvern male: ‘7’. 
nomiceformis, query =male of 7’. torridum; both common insects in 
same resorts,” It is possible that the male of torridum, if it is a 
valid species, would show structural characters separating it from 
nomiceformis. 
NOTHYLAZUS, Bridwell. 
This is a genus of African Prosopidide recently (Proc. Hawaiian 
Ent. Soc. IV, 1919, p. 126), separated by Bridwell, to contain such 
species as Prosopis heraldica, Smith; P. bevisi, Ckll.; and P. braunsi, 
Alfken. The mandibles are simple and acute at apex (bidentate in 
true Prosopis), and there are various other characters. A subgenus 
Anyleus, Bridwell, includes a couple of species with the scutellum 
and postscutellum modified. 
Noruy.L#us (ANYL&US), DENTIFERELLUS (Strand). 
This was described from Delagoa Bay, some 300 miles up the 
coast, but a couple of males from Natal (Durban, 31st July, 1916, 
C. N. Barker; Umbilo, 18th February, 1917, L. Bevis), appear to 
belong here, though the wings are brownish and not pure hyaline, as 
Strand seems to infer. The scutellum has two yellow spots on 
elevated areas, and the postscutellum is bidentate. The face is 
cream-coloured and the supraclypeal mark is large. 
PROSOPIS, Fabricius. 
PROSOPIS MELANOSOMA, Sp. Nov. 
2. (Type). Length 55-6 mm.; entirely black, except that the 
flagellum is dusky reddish beneath. Head rather large and thick ; 
face dull; clypeus high, its surface minutely rugose and sparsely 
punctured ; two sharp keels between antenne ; front well punctured ; 
inesothorax dullish, closely and finely punctured ; scutellum flattened, 
somewhat shining, the punctures very distinct ; area of metathorax 
large, well defined, coarsely sculptured, with a transverse median
