Extract

The rather numerous Ethiopian species of Dacus (s.l.) are very homogeneousowing to their reduced chaetotaxy and the very simple pattern of the wings; they have no praescutellar bristles, only a scutellar pair, and very often only twosupra-alar bristles, the anterior one being wanting. There are no species with astalked abdomen, or with spinose femora, or with elongated antennae, or withbanded wings.

page 85 note * This sexual dimorphism was first described by Prof. de Meijere (Tijdschr. Entom., xli, 1908, p. 127) and subsequently by Hendel (Supplem. entom., i, 1912, p. 13), both working on Oriental species. But there are some true Chaetodacus without this lobe, such as C. garciniae, Bezzi, and C. bipustulatus, Bezzi; C. cucumis, French, has no lobe, but also no praescutellar or anterior supra-alar bristles, and is therefore a true Dacus (s. str.).
