visible: nbdoinen short, with very 

 distinct lunulae j hind legs densely 

 pilose. 



23 (24) Abdomen dull, with only two pairs 



of lunulofi, the fourth segment being 

 entirely covered with dense pollen ; 

 hind tarsi of male fringed above 

 only at base vest it us, Bezzi. 



24 (23) Abdomen shining, with three pairs of 



lunulfe, the last segment not polli- 

 nose ; hind tarsi of male fringed 

 above throughout almost the whole 

 length oblifjwts, FaLr. 



117. Eumerus paulae, Herre-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 lunulae, 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 

 (exiUprs, 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 lunulse as 

 usual. 



A male from Durban, Xatal ( F. 3fuir) t another from Howick, 

 Xatal (J". P. Cregoe}, and a third from Nyasaland (Dr. J. E. S. 

 Old). A female from Durban (-F. Juir) differs from the following 

 species owing to its greater size (6'5 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. 



cJ $ . Length of the body 5 to 5 '5 mm. 



Yerv closely allied to the preceding, but smaller and distinguished 

 by the absence of the silvery abdominal pubescence, the white 

 lunuhe 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 triangle 

 and a few paler ones above the antennae, much constricted in the 

 middle, but the eyes not actually touching, merely close together 

 for a short distance ; frons of female of uniform width, strongly 

 shining, smooth, with short grey hair and a more or less distinct 

 transverse 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 sinning, flat, densely covered
