margin of the mouth, bare, with very scanty greyish hairs on the

 first two together, and not narrower, of a bright red colour and 

 showing a very minute terminal style. Proboscis black, thin, 5 mm. 

 long. Occiput with long and dense lemon-yellow hairs. Thorax 

 and scutellum black, clothed with long lemon-yellow hairs, without 

 black hairs. Haltères whitish. Abdomen black, with the same 

 hairs as on the thorax, with only a few black hairs on hind margin 

 of segments. Genitalia yellow-red, with long red spines. Legs 

 yellow, with only the coxae and tarsi black ; tibiae with yellow

Type Ç, and another specimen, from West Nyasa, 

 Mzimba, June 6, 1909 {JDr. IT. S. Stannus). 



G. Eurycarcnus, Loew (18G0). 



A very distinct African genus, which seems to be allied 

 to the South American Hderostyhmn, Macq. ; at least both 

 genera show the same sinuosity at the hind margin of 

 the eyes. Only a single species is known, which has 

 however, a wide distribution in the Ethiopian region. 

 E. pachyccrat'us, Bigot (1892), from the Cape, is very 

 doubtful, and belongs perhaps to the preceding genus. 



13. Eurycarcnus laticeps, Loew (1852). 



Several specimens of this easily recognised species from 

 West Nyasa, Cliintechi {Dr. H. S. Stannus) ; another male 

 specimen from Northern Nigeria, Lokoja, January 10, 

 1911 (J. J. Simj^son); a very small female (7 mm.) is 

 from Abu Jill, Kordofan (H. H. King). 



7. Lomatia, Meigen (1822). 



Of this distinct genus, which is abundantly represented 

 in the Ethiopian fauna, there are in the collection only 

 two specimens, belonging to two very different species. 



14. Lomatia inornata, Loew (185-1 — not of 1860 !). 



Loew has described two different species of Lomatia 

 with this same name : one in 1854 from Nubia, and 

 another in 1860 from South Africa. Since the two
