This interesting genus was supposed to be lacking on the European 

 and African continents, although represented by a few species in 

 Madagascar and the Seychelles. A few species from continental 

 Africa have been described by the writer while the present paper was 

 in press. The two new species described below belong to the section 

 of the genus with elongate male antennae and cell M { of the wings 

 lacking a group typified by Eriocera longicornis, Walker (Eastern 

 United States), to which species the new forms are obviously allied. 



ERIOCERA CAPENSIS, sp. n. 



Coloration black ; legs and halteres black ; wings brown ; fork of -B 3 

 shallow ; antennae of the male greatly elongated. 



Male. Length 7 mm. ; wing 8'5 mm. 



Female. Length 6'7 mm. ; wing 7 - 2 mm. 



Rostrum and palpi dark brown. Antennae of the male enormously 

 elongated, greatly exceeding the body ; first scapal segment large, 

 reddish-brown ; second segment small cyathiform, black ; flagellar 

 segments elongated, black, provided with long delicate hairs and a 

 row of scattered spinous projections. Frontal tubercle enormous, 

 globular, occupying the space between the eyes like a crest. Head 

 dark brownish-black. 



Thorax black, sparsely dusted with brownish-grey. Halteres black. 

 Legs black, the coxae, trochanters and base of the femora dark brown. 

 Wings suffused with brown ; stigma distinct, darker brown ; veins 

 dark brown. Venation (Plate III, fig. 8) : Sc extending beyond the end 

 of the sector ; r at the tip of M l and inserted on R 2 + s just before the 

 fork ; cell E., not deep ; rm and the deflection of -M\+ in alignment; 

 cell M-L lacking ; basal deflection of Cu i before, at, or just beyond the 

 fork of M ; Cu 2 a little shorter than the deflection of Cu^ 



Abdomen black.
