cence^ tliick below. The fore femora are black, sliinin2f, pale 

 yellow at the extreme apex, with black pubescence anrj White 

 hairs on their outer borders ; the other femora have al>o 

 some whitish pubescence, the fore tibise at the apex and all 

 the fore tai si black; the other le^^s are reddish yellow, the 

 tarsi with black pubescence. The wings are tinged with 

 yellow ; a very short appendix is present in all the specimens 

 except one. 



Two damaged S])ecimens from Ruwe, Lualnba River, 

 Congo Free State, area 10° S., 2&^ E., Feb. 1906 {Dr. A. 

 Yale Murray), 1906. 98, may possibly belong to this species, 

 which would thus have a wide distribution ; the specimens 

 are too poor to enable us to speak with certainty. It is 

 probable that with the advent of fresh material many varia- 

 tions will be found in this group represented by the typical 

 form of T. par of AValker, and that the species will only be 

 distinguished by small diffeiences, such as the colouring of 

 the legs and of their pubescence and colouring of the wings. 



Tahanus ohscuriorj ? , sp. n. 



The following specimens are in the British Museum 

 collection : — 



Type (female) and three other females from Wathen, 

 Congo Free State, 1904 (per Rev. W. H. BentJey) , 1905. 207. 



This species from West Africa is very closely allied to 

 Tahanus obscuripes, sp. n., from Abyssinia, and is only 

 distinguished from it by the browner wings with no appendix, 

 by the fore femora and tibige having no yellowish-white 

 l.airs but only black pubescence, and on the middle and poste- 

 rior femora the pubescence is here reddish yellow, not 

 whitish; the palpi are slightly daiker, with yellowish hairs 

 below, and the hairs on the face are darker than in Tahanus 

 obscuripes, and have some reddish-yellow hairs intermixed. 



Length 14 mm. 



Tabanus clari tibialis, ? , sp. n. 



The following specimens are in the British Museum 

 collection : — 



Type (female) from south end of Nyasa to Upper Shird, 

 C. Africa, 1500 feet, 14. i. 06 (E. L. Rhoades), and another 

 female from Upper Shire, 1500 feet, 20. i. 06 {E. L. Rhoades). 



A species approaching in general resemblance the group 

 represented by Tabanus par, VN'lk., but differing from all the 

 known species in tlie colouring of the legs and shape of 

 forehead ; for the present we place it in this group. 



A species with reddish-yellow abdomen, black thorax, clear 

 wings, and black legs with all the tihice white.
