Mid and hind femora with «nly sparse setu-

 distinct dorsal markings attennatu, Stein. 



Wherever tlie descriptions of the species have permitted 

 me to do so I liave iucluded them in the i\ey, but several 

 African species are so poorly described that this has been 

 fouud impossible. Those omitted are as follows : — cyclo- 

 ophthalma, Thomson, flavipes, Adams, inversa, Wiedemann, 

 punctipes, Thomson, multimaculata, Adams, sex-notata, Adams, 

 and trichopyga, Loew, 



Coenosia j)unctipes, Thomson. 



This species belongs to the same group as simili.9, Stein, 

 bnt from Stein's re-description I cannot place it satis- 

 factorily, tliough it will run to sitnilis in the key given here. 

 It ditfeis in having the femora all yellow. 



Copnosia humeralis, Stein. 



This specific name, humeralis, was preoccupied by humeralis, 

 Wiedemann^ when Stein used it for his species aud the 

 name acromiata was proposed to replace that of Stein's 

 species by Speiser. Though the Wiedemann species has 

 been removed to Atherigona and Stein's is a Pijgophora, 

 still the two were described as Canosia species, and the name 

 acromiaia, Speiser, must take the place o( humeralis, Stein, 

 in Pygophora. I have several times referred to Stein^s 

 species under the specific name humeralis, having failed to 

 note until recently that the name had been changed by 

 Speiser. 



With respect to preoccupied names, it may be well to note 

 that the specific ua.me Jlavi pes has been used three times in 

 this genus, the last time by Adams for an African species, a 

 fact which will prevent the renaming of that species should 

 it have been subsequently described under another name. 



Caricea fumisquama (Stein). 



A deep black species, with fuscous calyptrse and halteres, 

 infuscated wings, and the thorax and abdomen without 

 markings. Arista pubescent; frons flat and appearing
