The Crane-fiefi of South Africa. 191 



Type in the South African Museum. 



This tiny crane-fly is related to the much larger E. bonae spei, 

 Alexander (South Africa), but is readily told by the closed cell 1st Ma 

 a character possessed by most European species and two Nearctic 

 species of the sub-genus Empeda. 



SUB-GEN. ERIOPTERA, Meigen. 

 ERIOPTERA (ERIOPTERA) PERINGUEYI, Bergroth. 

 A female from Krantzkop, Natal, November, 1917 (K. H. Barnard). 



ERIOPTERA (ERIOPTERA) CLARIPENNIS, sp. n. 



Coloration dark brownish-black, dusted with grey ; wings sub- 

 hyaline, the extreme base yellowish, veins dark brown ; cell 1st Mo 

 open, second anal vein short, straight. 



Female?. Length 3 mm.; wing 4 - 4 mm. Fore leg, femur 1'8 mm.; 

 tibia 2*3 mm.; hind leg, femur 2'1 mm., tibia 2'4 mm. 



Rostrum and palpi dark brownish-black. Antennae dark brown, 

 the flagellar segments oval, densely clothed with an erect pale 

 pubescence. Head dark, sparsely dusted with grey. 



Prouotum with the scutum dark, dusted with grey, the scutellum 

 clear yellow on the sides, infumed medially above. Mesouotum black, 

 dusted with grey ; scutellum broad, the apical third conspicuously dull 

 yellow. Pleura dark, sparsely dusted with grey. Halteres brown. 

 Legs with the coxae small, dull yellowish-brown ; trochanters pale 

 brown ; fore femora dark brown except the extreme bases, which are 

 paler ; tibiae and tarsi dark brown ; middle and hind legs similar but 

 the femora brown, darkened at the tips. Wings greyish subhyaline ; 

 stigma indistinct ; veins dark brown, slender and very distinct ; extreme 

 base of wing yellowish. Venation (Plate III, fig. 10) : Sc* not greatly 

 removed from the tip of 8c l ; r present, connecting R 2 some distance 

 beyond the fork of -R 3 + 3 ; -Ro + 3 moderately long, a little longer than 

 r-m ; Rs long, straight ; basal deflection of -B 4 + 5 , r-m and the deflec- 

 tion of M l + 2 short, in alignment; cell 1st M., open by the atrophy of 

 m ; basal deflection of Cu v inserted at or slightly beyond mid-length of 

 vein M" 3 ; second anal vein straight. In its general features the 

 venation suggests E. laticeps, Alex., or E. pilipennis, Alex. (Western 

 United States). The condition of the second anal vein is more like 

 the subgeuus Acyphotia, and this group of species may be considered 

 as belonging there, although the appearance of the species is quite 

 different from typical Acyphonae. 



Abdomen dark brownish-black, the pleural region yellowish. 

 Hypopygium dull brownish-yellow, the valves blunt. In the unique
