76 Miss G. Ricardo on the xVsIlida?. 



South African Region. 



The species oF Heligmoneura described from this region 

 are : Heligmoneiira annu/ilarsis and siimata, Loew, from Caf- 

 fraria; H. deserticcla, Karscli, from E. Africa ; H. monohia, 

 Speiser, from Eryfliroea ; H. tiudn, Bezzi, from Ervt]>r?ea : 

 H. modcsta, T?iL;ot, from Gaboon ; and H. rothkircJiii, Speiser, 

 from Kameroons. None of these species are represented in 

 the Brit. ^lus. Coll., except H. sinuata. H. anmditarsis must 

 be nearly allied to it, but the fork of the third vein is said to 

 be only very slightly curved, and the hind and middle tibiae 

 with only bl ick spots. The otipositor is larger tlian the 

 last two segments of abdomen — not equals as in H. sinuata. 



Length 10 mm. 



H. deserticola is described very shortly ; the face with 

 two rows of A^ery black biistles down the middle, a ciia- 

 racteristic not very probable in a species of this genus. 

 H. monobia is descril)ed as a black species with yellow legs. 

 H.nuda is described by the author as very like an Ommatius 

 spacies, and, as he had not seen any specimen with perfect 

 antennffij the question of genus remains undecided. H. rotk- 

 kirchii, Speiser, from Dnala, Kameroons, is described as a 

 very tine species, 20i mm. long. Blackish with the ordinary 

 yellow-grey tonientnm of Asilidse; the ])ubes ence on the 

 abdomen yellow, long at the sides. Palpi black, red-haired. 

 Antenna reddish yellow. Legs yellowish ; the femora at 

 apices, most of the tarsi, and the hind tibiae black ; described 

 from one fema'e specimen. 



Three new species are here described.
