Type c? , a single specimen from 

 11. xi. 1907, " caught in bush " (Dr. 



El" MERITS. 115 



cimen from Obuasi, Ashanti, West Africa 



W. J/. Graham). 



122. Eumerus feae, Beszi (1912). 



Readily distinguishable, owing to the breadth of the yellow 

 margin of the scutellum and to the narrowness of the frons of the 

 female ; thoracic stripes and abdominal lunulse well marked. 



This species, recently described by me from Fernando Po and 

 the French Congo, seems to be widely distributed in West Africa. 

 A male and three females from Obuasi, Ashanti, " caught on bush 

 and flowers," vii.-xi. 1907 (Dr. W. M. Graham) ; a female from 

 Oshogbo, S. Nigeria, 20-30. ix. 1910 (Dr. T. F. G. Mayer} ; a 

 female from Ibadan, S. Nigeria (Capt. Leslie) ; and a male from 

 Zomba, Nyasaland (Dr. H. S. Stannus). The last-mentioned 

 specimen has the antennae, face, and smaller genitalia reddish ; it 

 probably belongs to a distinct species. 



123. Eumerus axinecerus, Speiser (1910). 



Distinguished by its antenna? and fore legs being red, and by 

 the abdomen being more or less red at the sides near the base. In 

 my table of 1912 I placed this species among those in which the 

 abdomen is black ; usually, however, the red colour, as described 

 by the author is quite distinct ; it seems to be distinguished from 

 litnatus owing to the colour of the legs, in which only the knees 

 are reddish. 



A pair from Durban, Natal (F. Muir). 



121. Eumerus quadrimaculatus, Macquart (1855). 



I refer with some doubt to this species two males from Blantyre, 

 Xyasaland Protectorate, 20. iv. 1910 (Dr. J. E. S. OU). The 

 species represented by the specimens before me seems to be allied 

 to the foregoing, and is very different from that recorded under 

 the same name by Prof. Herve-Bazin, Rev. Zool. Afric. iii. 1913, 

 p. 78. Except- for the fact that the femora are rather swollen, I 

 should have referred the present specimens to E. beyuaerti, H.-B. 



125. Eumerus triangularis, Herve-Bazin (1913). 



A very distinct species owing to its very broad and flattened, 

 almost glabrous hind legs, its entirely bare eyes, and the peculiar 

 shape of the second antennal joint. 



The shape of the hind legs in this species is similar to that 

 seen in erythrocerus ; the front ocellus is distant from the other 

 two ocelli ; the second antennal joint is prolonged as a long lamella 

 on the inner side of the last joint, much as in the species of Ptecticv* 

 or of Syntormon ; the abdomen is rather elongate and narrow, even
