{Publislicd by permission of the Trustees of the British Museum.) Hippobosca fulva, sp. n. Q.--Length (1 specimen) 3'5 mm.; width of head 1*4 mm. ; width of front at vertex 0'6 mm.; length of wing 5 mm. Extremely small species : thorax {exclusive of scutellum) and abdomen deep tawny, thorax entirely devoid of markings ; scutellum, except hind border, pale strawyellow, with four relatively stout, ochraceous bristles on hind border on each side of middle line; wings nearly hyaline, faintly tinged

Head: triangular plate on vertex wax-yellow ; sides of front ochraceous, anterior border of front raw-sienna-coloured, narrow ; frontal stripe cinnamonrufous ; face yellowish-white, its lower edges fringed with black hairs, under surface of head clothed with Naples-yellow or pale yellowish hair; palpi dark brown ; antennae tawny ochraceous. Thorax: short bristles or spines in front of base of each wing three in number, black, and arranged in a transverse row, longer hair or bristles on dorsum sparse and yellowish in colour ; fine hair on pleurae and pectus pale yellowish; hind border of scutellum ochraceous or tawny ochraceous. Abdomen clothed with pale yellowish hair. Wings : costa (at least in typical example) dipping below first longitudinal vein between a point approximately on a level with commencement of distal fourth of first basal cell and end of first longitudinal vein ; costa, except at base, bearing a single row of short bristles, arranged at more or less regular intervals ; third longitudinal vein straight and much closer to second longitudinal vein and costa than in case of H. capensis, v. Olf., so that the submarginal cell is conspicuously narrower than in the species mentioned ; neither anterior transverse vein nor adjacent portions of veins infuscated. Halteres ochraceous. Legs: front coxae, except at base, pale straw-yellow ; hair and bristles for most part agreeing with ground-colour, two or three long bristles at tips of hind femora above, and short bristles at distal extremities of hind tibiae dark brown. NOKTHERN (NORTH-EABTERN) RHODESIA : Nawalia, 21.ix,1911, on haartebeeste (Alcelaphus lichtensteini, Peters) {LI. Lloyd : presented to the British Museum by the Entomological Research Committee). The species described above cannot possibly be confused with any of its congeners previously known, and its discoverer is to be congratulated on having made so interesting an addition to the extremely limited number of recognised species of Hippobosca.
