A Revision of the Bombyliidae (Diptera) of Southern Africa. 709* below very narrow in front and scarcely broader than across upper part of buccal cavity and with short and sparse hairs. Thorax compressed laterally, more or less arched above, the pleural parts perpendicular, with the space between humeral callus and base of wing on each side and separating the dorsal part from mesopleural sclerite, deep and groove-like, with the pronotal part well developed, with the transverse suture, visible lateral

A Revision of the Bombyliidae (Diptera) of Southern Africa. 709* below very narrow in front and scarcely broader than across upper part of buccal cavity and with short and sparse hairs. Thorax compressed laterally, more or less arched above, the pleural parts perpendicular, with the space between humeral callus and base of wing on each side and separating the dorsal part from mesopleural sclerite, deep and groove-like, with the pronotal part well developed, with the transverse suture, visible laterally between it and mesonotum, well back and near base of wings, with the upper surface of thorax anteriorly and laterally with comparatively sparse bristly hairs and scaling; scutellum distinctly lower than base of thorax, its posterior margin indented medially, the posterior margin of scutellum thus bifid (text-fig. 210), the indentation separating two tumid prominences, with the upper surface of scutellum bearing some sparse bristles laterally on each side and scaling discally in basal half; pleurae well de- veloped, with the mesopleural sclerite Text-fig. 210. — Scutellum of , i n i n T Othniomyia tylopelta n. gen. prominently developed, convex and and n Sp situated rather far forwards, with the sternopleuron also broad and well developed and with the pteropleuron situated more forwards and not directly under wing-bases as in many genera, with the pleurae comparatively bare, very sparsely-scaled, bristly hairs on bristles being present only on mesopleuron, with the metapleural parts bare, but with bristles on metapleuron in front of halteres. Wings (text-fig. 211) with the costal margin undulating, the costal cell being broadened just beyond middle, with 3 submarginal cells and 4 posterior cells present, with the first posterior cell broadly open on hind border, with the enclosed third submarginal cell very large and broad and the marginal cell much broadened in apical part
