Glossina severini, Newstead. The type specimen of this species is a male in the Musee RoyaldHistoire Naturelle de Belgique. It was taken in the Congo FreeState, and bears the following data :— Lac Mouro (Riv. La Lavua),Mai, 1907. It had evidently been preserved in alcohol, so that itis highly probable that the colours may have been slightly changed;but on comparing it with a number of examples of Glossinafuscipleuris, Aust., from the Congo Free State, and also somespecimens of Glossina fusca, Walk., all of which had beenpreserved in the same way, one could readily separate both 333 G. severini, , and G. fusciplenris from G. fusca by the muchdarker colour of the pleurae and the hind coxae. A second example from the same Institution as the type bore thelabel Congo only. As to the affinities and characteristics of this new tsetse-fly, onegathers from the two examples that, so far as the colour of the hindcoxae and pleurae are
