If we take the structural characters of the male genital armature,we find that it is very closely related to G. medicorum, Aust., fromwhich it may, however, be readily separated by the curious rudi-mentary harpes, the greater length of the marginal hairs of theeditum, and furthermore by the greater length of the lateralbranches of the hairs of the arista (fig. 2 a).. Fig. 2. (a) Glossina severini, n. sp. Terminal portions of the hairs of the arista.(b) Glossina medtcorum, Austen. Terminal portions of the hairs of the arista. Soon it is hoped that perfectly fresh material will be availablefor a more complete study of the colour and pattern of this new 334 tsetse-fly, as too much importance cannot be attached to the colourin the existing specimens, owing to the fact that changes, as alreadystated, may have taken place. However this may be, the structuralcharacters as set forth in the above diagnosis will very readily assistin the future determination of this interesting addition to the genusGlossina. Glossina austeni, Newstead. Twelve examples of this recently discovered tsetse-fly, consistingof two males and ten females, were submitted to me for identificationby Dr. Hermann Morstatt, Amani. The examples in question werecaptured at Nyussi, Tanga district, January and February, 1913. Though this is the f
