middle at the lower edge and are directed obliquely towards the 

 apex of the femur ; these bristles are in all probability tactile hairs. 



Described from two males taken by Dr. H. Brauns at Stellen- 

 bosch, Cape Province, South Africa, November, 1915. 



According to Dr. H. Brauns, females, seen at the same place 

 and under the same conditions, therefore evidently of the same 

 species, were smaller and black. I have not seen examples of that 

 sex. 



The salient characters of A. hraunsi are found in the broad front 

 of the male, the spur-like apex of the hind metatarsus, the uni- 

 colorous ocher yellow abdomen, and the milky white, unspotted 

 wings. By these characters it differs conspicuously from all other 

 described species and can easily be distinguished from the two 

 previously knoAvn in the Ethopian Eegion: Atherix hinominata 

 J. Bequaert (= Atherix longipes Loew, nee Bellardi)^ from 

 Bloemfontein, Orange Eiver Colony; and A. disciclara Speiser,^ 

 from Tiko, near Victoria, Kamerun. Loew campares A. hinominata 

 with A. crassipes Meigen, but that species has been made the type 

 of Atrichops VerralP on account of the front in the male and the 

 side-cheeks in both sexes being practically bare. Whether A. hi- 

 nominata agrees in this respect with A. crassipes seems extremely 

 doubtful; but A. hraunsi has the front densely hairy from the 

 ocelli to a short distance above the antennas and the side-cheeks 

 also are pubescent. 



The genus Atherix Meigen (including Atrichops Verrall) is 

 known from all over the world with the exception of South 

 America. Of the thirty-one described species two are doubtful, 

 seven occur in the Palearctic Eegion, three in the Ethiopian, eleven 



1 Atherix longipes H. Loew, Wiener Ent. Monatschr., 7, 1863, p. 12. This 

 specific name being preoccupied In the genus by Atherix longipes BeUardi 

 (1861) of Mexico, I propose tliat Loew's Soutli African species be called 

 Atherix hinominata. 



For the convenience of South African entomologists Loew's brief descrip- 

 tion of A. hinominata is reproduced here: " — Ex Ather. crassipedis afflni- 

 bus. Fusco-nigra ,tertio antennarum articulo, scutelli margine abdomineque 

 subfulvis, primo hujus segmento praeter marginem apicalem atro, segmento 

 secundo maculis tribus atris ornato, segmentis tribus sequentibus atro-fas- 

 ciatis, segmento sexto subtiliter atro-marginato; pedes longi, cum coxis fulvo- 

 testacei, tibiis tarsisque anterioribus tarsisque posticas pi-aeter basim nigris, 

 tibiis posticis tarsorumque posticorum basi fuscis; alae infuscatae, in disco 

 subnebulosae, stigmate fusco, furca. venae longitudinalis tertiae perlonga.
