Type in the South African Museum. 



This fly agrees closely with the rather insufficient description of L. 

 claduroneura, Speiser (Kilimanjaro) a somewhat larger fly,with the 

 petiole of cell M l still shorter, only about one-fourth the length of the 

 cell itself. 



LlMNOPHILA GRISEICEPS, Sp. 11. 



Related to L. natalensis ; head light grey; antennae elongate, black ; 

 wings greyish-brown, the costal region a little darker ; subcosta long, 

 basal deflection of -R 4 + 5 very short. 



Female. Length 9'4 mm. ; wing 10 mm. 



Related to L. natalensis, sp. n., differing as follows: size larger; 

 head clear light grey, not reddish-brown as in natalensis, the eyes much 

 closer together at the vertex. Antennae black, the first scapal segment 

 grey pruinose ; the flagellar segments very long and slender, so the 

 antenna is considerably longer than in the males of natalensis the 

 only sex of this latter species yet made known. Thoracic notum dark 

 brown, brightened only on the humeral region of the praescutum and 

 the caudal half of the postuotum, which are more reddish. Wings 

 darker, especially cell C, which is brownish. Venation : Sc.^ longer than 

 Si'i and entering If, slightly before the fork of .R.,+ 3 ; Bs longer and 

 less arcuated at origin ; basal deflection of -B 4 + 5 very short to almost 

 obliterated, r-m being correspondingly longer ; petiole of cell J/j 

 shorter ; cell 1st M% broader. 



Habitat. South Africa. 



Holotype, $ , Oudebosch, Caledou, Cape Colony, altitude 1500 ft.,

Type in the South African Museum. 



LlMNOPHILA KHODESIAE, sp. 11. 



Related to L. frngi (Bergr.) ; the first flagellar segment yellow; 

 thoracic pleura with a broad silvery stripe ; wings with a delicate pale 

 brown dotting along the veins and at the wing margin ; Rs angulated 

 and spurred at origin ; cell 1st M 2 small, subquadrate. 



Male. Length about 6'5mm. ; wing about 7 mm. 



Rostrum and palpi dark brown ; antennae dark brown, the second 

 scapal segment paler brown ; the first flagellar segment light yellow ; 

 first scapal segment very long ; flagellar segments beyond the fourth 

 slender, elongate-cylindrical. Head dark with a heavy yellowish -grey 

 bloom, an indistinct brown longitudinal mark on the vertex ; head 

 strongly narrowed behind as in this subgenus (Pseudolimnophila, 

 Alex.). 



Prouotum conspicuous, grey, with a narrow brown dorso-medial line.
