In November 1939, Mr. G. H. E. Hopkins, Senior Medical Entomologist in Kampala, reported to me that he, together with Mr. T. W. Chorley, had discovered Glossina nigrofusca, Newst., in Uganda. As G. nigrofusca is a rare West African species, this find was rather unexpected, and he asked me to check the identification. The exterior characters of the two specimens sent in were entirely those of G. fusca, but after dissecting the male genitalia of a West African G. nigrofusca, I could not but agree that the Uganda specimens were quite as like the latter species.
* The latter argument has resulted from a discussion of the question with Dr. A. S. Corbet, whom I wish to thank for communicating his experience of this point in Lepidoptera.
