It may be added that, according to Laveran,* Tdbanus fasciatus, 

 Fabr., occurs in Senegal, while Surcouf and Roubaudf state that the 

 species is very common on all the rivers in French Congo, and that 

 it attacks human beings and cattle. 



Dead specimens of T. fasciatus, such as that from which the figure 

 has had to be prepared, unfortunately afford but a poor idea of the 

 brilliancy of the colours in the living insect, as to which Dr. J. L. 

 Todd writes as followsj : " While living this fly is a very beautiful 

 object. The eyes are a bright, metallic, pea-green, and the colours 

 of the body are very much brighter than in dried specimens." Writing 

 of the habits of the species, as observed by him on the Gambia and 

 in the Congo Free State, during the expeditions of the Liverpool 

 School of Tropical Medicine, Dr. Todd says : " This insect was seen 

 only near water. Most of the specimens were taken while travelling 

 by steamer or in canoes. Two specimens were, however, caught in 



the houses of Europeans It flies strongly, and is often seen 



on board steamers over 100 yards from the river's bank." Dr.
