Congo Free State (September 15th, J903). This is an important 
record, and furnishes a further proof of the ready means by which 
these parasites may be introduced into a new and uninfected region. 
Flies of this genus were also caught on camels and cattle at 
St. Louis, Senegal, May, 1903 ; their freshly deposited larvae were 
marked with very delicate tracings. Unfortunately the specimens 
and drawings were lost while in the hands of the Authorities of the 
British Museum and cannot now be traced.
