88 YAKIETIES OF GLOSSIXA PALLIDIPES. 



the interrupted dark-brown bands occupy more of the upper 

 surface of the abdomen. 



Legs buff-coloured ; middle tarsi, like the front pair, entirely 

 pale* ; the last two joints of the hind tarsi (except the penultimate 

 at the extreme base) dark-brown. 



The typical specimens are a ^ and 9 from Kilima Njaro 

 (F. J. Jackson), in the British Museum collection. 



Varieties. — A ^ and $ from "Witu, " caught in Witu town " 

 (British East Africa Companf/), are much below the normal size, 

 since they do not exceed 7| millim. (3^ lin.) in length ; they 

 are further distinguished by the pale longitudinal stripe on the 

 median line of the abdomen being wider than usual, especially 

 in the 9 > in which also it is less sharply defined, owing to the 

 interrupted dark transverse bands dying away towards the 

 median line. In the shape and size of the eyes, and especially 

 in the narrowness of the front in the male, however, these 

 specimens agree with the typical foim. 



Sevei'al specimens from British East Africa ( Vet.-Capt. 

 A. J. Haslam) and Kilima Njaro (F. J. Jackson), though other- 

 wise agreeing with the typical form, have the median pale 

 longitudinal stripe on the abdomen wider and less sharply 

 defined, since the intenupted dark transverse bands die away 

 towards the median line. Possibly this appearance is in part at 

 least due to immaturity. 



Distribution of Gl. pallidipes, sp. nov. 



Of this species, which would appear to be the East African 

 representative of Gl. longipalpis, Wied., I have examined a series 

 of 81 specimens (63 ^ ^ and 18 ? ? ), from various localities, as 

 indicated below : — - 



1 (J , locality unknown (forwarded for identification by 

 Mr. J. F. Quekett, Durban Museum) ; 1 9 > " Country south of 

 Mashonaland " {Mr. HooJce : presented by the late J. C. Mansel- 

 Pleydell) ; 1 }, Shire Highlands, 1893 (H. H. Johnston.— 

 " Caught in a part of the Shire Highlands where we had thought 

 there was no Tsetse " : exti'act from letter from Mr. Johnston 

 (now Sir H. H. Johnston, K.C.B.), dated October 22nd, 1893, to 

 the late Sir Wm. Flower, K.C.B., enclosing specimen) ; 2 ^ ^ , 

 British Central Africa — exact locality uncertain, but probably
