The occurrence of this Somaliland species in the Arabian portion 

 of the East African Subregion of the Ethiopian Region is, of 

 course, in no way surprising, since other and better known African 

 Diptera, such as Tdbanus biguttatus, Wied.,* and a Tsetse-fly 

 (Olossina tachinoides, Westw.) are found to the east of the Strait 

 of Bab-el-Mandeb.

The eight females of this species in the Museum are all from 

 Ashanti, and no examples of Hcematopota torquens have yet been 

 received from elsewhere. The localities, etc., of the Museum 

 specimens are as follows : Insu, Ashanti, August 17th, 1906, and 

 September 4th, 1907, " caught in carriages on Gold Coast Govern- 

 ment Railway " (Dr. W. M. Graham, W.A.M.8.] ; North Ashanti, 

 Northern Territories, Gold Coast, February, 1908 (G. C. Dudgeon). 

 Mr. Dudgeon, who observes that the eyes of H. torquens in life are 

 " dull green," remarks that this is "a common species in the 

 Ashanti forests," where it " attacks travellers in hammocks." 

 According to Dr. W. M. Graham, the specimens found on the Gold 

 Coast Government Railway, where the fly is frequently met with 

 in the carriages in the month of September, probably come from 

 the Jym River, which runs parallel with the line for a considerable 

 distance. 



Care is needed in order to distinguish Hcematopota torquens, 

 Austen, from H. cordigera, Bigot, another West African species, 

 which is also found in Ashanti, as well as in Assinie (Ivory Coast), 

 Northern Nigeria, and the Congo Free State ; once the points of 

 difference are appreciated, however, a glance at the scutellum and 

 the first joint of the hind tarsi is all that is necessary. With
