Bombylius analis Fabricius 



B. analis Fabricius, 1794, 'Ent. Syst.,' IV, p. 408. 



The collection contains six males and eight females from the follow- 

 ing localities: 5 males, Stanleyville, March and April, 1915; male, Boma, 

 June 18, 1915; 7 females, Garamba June-July, 1912; female, Faradje, 

 Nov., 1912. 



Bombylius argentatus Fabricius 



B. argentatus Fabricius, 1805, 'Syst. Antl.,' p. 135. 



There is a poorly preserved female from Faradje, Nov., 1912. The 

 wings are marked much as in the genus Hemipenthes Loew. The shape of 

 the third antennal segment distinguishes the species from any other yet 

 described. 



Bombylius rufiventris Macquart 

 B. rufiventris Macquart, 1846, 'Dipt. Exot.,' Suppl. 1, p. 116. 

 Male, Banana. Sept., 1915; female, Boma, June 17, 1915. The 



male is in almost perfect condition and while the female is somewhat 



damaged it is quite recognizable. 



Bombylius auricomus Bezzi 

 B. auricomus Bezzi, 1924, 'Bomb. Ethiopian Reg.,' p. 44. 

 There is a single, largely denuded female from Stanleyville, April 

 10, 1915, which belongs to this or to an undescribed species. The wings 

 are largely tinged with brownish yellow, which fades out apically, while 

 the sides of the abdomen are yellow-haired at least on the basal three- 

 fifths and there are numerous black bristles apically. Owing to the con- 

 dition of the specimen, it is not possible to state with certaint}^ that it is 

 this species. 



Bombylius species 

 A single, badly damaged specimen from Bafwabaca, Jan., 1910, 

 belongs to a species not otherwise represented in the collection, but it is 

 impossible to determine it. 



Systœchus Loew 



Systoechus melampogon Bezzi 

 S. melampogon Bezzi, 1911, Trans. Ent. Soc. London, p. 609. 

 The collection contains a single female from Faradje which, even 

 though it is largely denuded, I believe belongs here. The specimen was 

 captured in January, 1913.
