BLOOD-SUCKING FLIES IN UKWEEE. 151 



Further on (Band II., p. 304), in writing of tiie 

 Wabuni, a scattered tribe of Galla, of whom there are 

 several settlements on the north shore of the Lower 

 Juba, while they extend as far as 3' S., the author 

 says : — 



" Like the Galla and Somali they live chiefly by 

 hunting. Moreover, they keep small domestic animals, 

 but no cattle, since in the territories occupied by them 

 the Tsetse-fly makes this impossible."

 pp. 289-290). 



A note criticising E. C. Buxton's remai'ks printed 

 above [41], which are considered by Newman to refer to 

 Heemaiopota (Family Tabanid*).— " All that Mr. Buxton's 

 note proves is that ' clegs ' in South Africa are numerous, 

 and that their bite is innocuous to human beings." 



45. 1872. H. M. Stanley. 



" How I Found Livingstone. Travels, Adventures, 

 and Discoveries in Central Africa ; Including Four 

 Months' Residence with Dr. Livingstone " (London : 

 Sampson Low, Marston, Low, and Searle), pp. 87-91, 

 213, 330, 354. 



Tsetse-fly near Bosalio, in Ukwere (about 20 miles 

 inland from Bagamoyo). Three different species of biting 

 flies were met with, and even found in the author's tent. 

 The first, called Mahunga by the natives, is about an 

 inch long and evidently a species of horse-fly (Tabanus). 

 Stanley's men " unanimously stated that its bite was fatal 

 to horses as well as to donkeys." " This fly, along with a 

 score of others, attacked my grey horse, and bit it so 

 severely in the legs that they appeared as if bathed in 

 blood " (pp. 88-90). 



Of the second species of biting fly only one specimen 

 was seen during the author's stay at that particular camp : 

 the description is too vague to admit of its identity being 

 determined (p. 90). 



" The third fly, called ' chuf wa,' pitched a weak alto- 

 crescendo note, was a third larger than the house-fly, and 

 had long wings. If this insect sang the feeblest note, it 

 certainly did the most work, and inflicted the most injury.
