Side view of hypopygium and ventral view of aedeagal apparatus of £ Exoprosopa nebulosa n. sp. Exoprosopa decipiens-section The species Exoprosopa decipiens Bezz. was placed in the nemesis-group of the subgenus Exoprosopa by Bezzi, but as it differs from nemesis not only in the wing- pattern, but in other venational characters as well, it obviously cannot be included in the same section or group as the latter. Its wing-pattern, which is strikingly similar to that of Litorrhynchus, also resembles that of the Egyptian Efflatoun-Beyi Par. If wing-pattern be accepted as a criterion of a sectional or group status it should find a place in a section comprising such species as Efflatoun-Beyi Par. and possibly also curvicornis Bezz. and senegalensis Macq. which Bezzi referred to the grandis-group. As there are no other South African species resembling it, it is here appended to the end of the arbitrary Defdippia-group as a provisional section by itself of which the wing-characters and other features may be gleaned from the specific description given below. Exoprosopa decipiens Bezz. (Bezzi, pp. 277 and 287 and fig. 27, The Bombyliidae of the Ethiopian Region, 1924.) This species, of which the wing-pattern cannot be confused with any other South African species of Exoprosopa, is characterized as follows:
