117. Eumerus paulz, Hervé-Bazin (1913). 
A pretty species, very distinct in the male sex, owing to the 
silvery pubescence on the abdomen, which almost entirely “conceals 
the usual lunule, and owing to the enormous genitalia, which are 
usually exserted. 
This and the two following species belong to a peculiar group, 
which is perhaps allied to the Mediterranean argyropus, Loew 
(exilipes, Rondani); in the latter species, however, the eyes of the 
male are in contact for a long distance as usual. The female is 
like the male, but has no silvery pubescence and only normal hair, 
and on the abdomen there are three pairs of distinct lunule as 
usual, 
A male from Durban, Natal (# Muir), another from Howick, 
Natal (J. P. Cregoe), and a third from Nyasaland (Dr. J. E. 8S. 
Old). Atemale from Durban (#. Muir) differs from the following 
species owing to its greater size (65 mm.) and more, obscure 
wings, with distinct vena spuria and dark stigma. 
It seems to be a widely distributed species, very different from 
argenteus of Walker and ‘Loew. 
118. Eumerus serratus, sp. n. 
3 2. Length of the body 5 to 5°5 mm. 
Very closely alhed to the pr oe si but smaller and distinguished 
by the absence of the silvery abdominal pubescence, the white 
lunulx being as distinct as usual. 
Head pure black, not purplish blue as in the preceding ; frons 
of male shining, with erect dark hairs towards the vertical | tr langle 
and a few paler ones above the antenne, much constricted in the 
middle, but the eyes not actually touching » merely close together 
for a short distance; frons of female of area width, strongly 
shining, smooth, with short grey hair and a more or less distinct 
ieee band of whitish dust below the middle ; ocelli forming 
an equilateral triangle ; occiput rather prominent above, with long 
white hairs behind the ocelli ; ; eyes of male bearing short pale hair, 
those of the female almost bare; face shining, flat, densely covered
