J. W. SCOTT MACFIE — THE DISTRIBUTION OF GLOSSINA 



The plate (PI. VII) indicates how unlike these tsetse-flies are to the typical 

 G. palpalis, but in view of the structure of the male genitalia, it is, I suppose, 

 only possible to relegate them to that species. 



Tsetse-flies of this type were collected from every part of the province and 

 were often found associated with typical G. palpalis and G. tachinoides. At 

 only a few places were typical G. palpalis found alone. A larva deposited by 

 one of these flies measured 4 mm., by 1.5 mm., by 1.5 mm. 



Mites found on Tsetse-Flies. 



On a few specimens of both G. palpalis and G. tachinoides, taken during the 

 months of May, June, and August, minute red mites were found attached to the 

 abdomen, thorax, or legs. They were easily detached by the point of a brush, 

 and in one instance the mite voluntarily left the tsetse-fly and was found 

 crawling over the floor of a store-box. They were of two distinct types, and 

 although at the same seasons other mites were common on such insects as 

 mosquitos, Chrysops, Stomoxys, etc., the forms found on the tsetse-flies were not 

 observed on any other insects. Specimens of these mites were submitted to 

 Mr. S. Hirst, of the British Museum, who very kindly examined them, and 

 expressed the opinion that they were larval forms of Trombidiidae, and 

 probably belonged to the genus Trombidium in its wide sense. 



Fulani Cattle. 



The janyali, or cattle-tax, levied at the rate of Is. 6d. per head on all the 

 Fulani cattle in the province, furnishes interesting statistics as to the distribution 

 of the herds. The table given below shows in the first column the sum collected 

 in each district for the year 1911, in the second the approximate area of the 

 districts, and in the third the number of head of cattle per square mile. The 

 figures, which are, of course, only approximate, indicate with accuracy the 

 districts in which the experience of generations has taught the natives they may 

 safely graze their herds.

 collected on the dwarf cattle found in Egbe, Eri, Of a Ora, Oro, Osi, Idofin and Awtun.
