Glossina morsitans (Fig. 237), carrier of many trypanosome diseases of animals and of the newly arisen and still narrowly limited Rhodesian sleeping sickness, is the most widely distrib- uted species of tsetse fly, occurring all the way across Africa.

(After Austen.) from Senegal to southern Sudan and Abyssinia on the north, to northeastern Transvaal and Zululand on the south (Fig. 231, \\\). This is also the best known species, and is the one which has attracted to itself the attention of big-game hunters in Africa for many years. It is slightly smaller than G. palpalis and much lighter colored, with very inconspicuous markings on the gray thorax, and with more or less distinct dark bands, not con- tinuous across the middle line, on the buff colored abdomen.
