Walk., Plate IV., fig. 25), from the vicinity of Mpimbi, Upper 

 Shire River, 20 miles west of Zomba, Nyasaland Protectorate, 

 taken by a native in May, 1905, and presented by Major F. B. 

 Pearce, C.M.G., were labelled : " In large numbers, following 

 the nswala antelope " [Aepyceros melampus]. Dr. J. E. S. Old, 

 who on another occasion was himself attacked by P. oldii, wrote 

 that it " makes a loud humming noise, resembling that of a large 

 bee, and on alighting immediately thrusts its long proboscis through 

 the skin." In a recently published paper Dr. Old stated that 

 " Pangonia hovers for a few seconds, alights, and then deliberately 

 punctures, like a needle, with its extraordinary proboscis."* As 

 to native African names of Pangonia, in the Nyasaland Protectorate, 

 according to Dr. Old, specimens belonging to the genus are apparently 

 known to the Angoni as " Chimbu," to the Ankondi as " Mbwari," 

 and to the Ahenga as " Nimbu." 



So far as can be ascertained, no observations 

 Life-history, have yet been made as to the life-history of any 



species of Pangonia. 



Although in parts of the Anglo-Egyptian 



Pangonia Sudan, such as the Red Sea Province, Pangonia 



and Disease, magrettii, Bezzi, and P. ruppellii, Jaenn., are 



said to be connected by natives with sickness 

 and mortality among cattle and camels, while on one occasion in 

 New Caledonia a species of this genus is stated to have been 

 concerned, with Stomoxys calcitrans, in the dissemination of an 

 epidemic of anthrax, it has not yet been proved or even seriously 

 suggested that any species of Pangonia is the regular transmitter of 

 any micro-organism pathogenic to animals or man.
