Turner ; British Museum). The structure both of palpi and antennae in this species is very striking, though both these characters represent only a further develop- ment of the specialisation of those organs observed in P. crassicornis. Prostethophyma bechuana, sp. n. (Text-fig. 4.) cJ {type). Antennae filiform, straight, extending well beyond the pronotum. Face moderately oblique, coarsely punctured. Frontal ridge fairly broad, parallel-sided, shallowly excavate in the region of the ocellum, coarsely punctured. Fastigium of vertex projecting well forward,. Fig. 4.—Prostethophyma bechuana, sp. n., ^. Elytron. considerably longer than broad, antero-lateral margins almost straight, forming an acute, scarcely rounded, apical angle ; the surface feebly concave, with a distinct, though irregular, median carinula which extends on to the occiput. The latter with transverse rugosities on both sides of the carinula. Foveolae of vertex not developed, but their spaces fairly broad and punctured. Maxillary and labial palpi with all joints normal, not dilated. Pronotum densely, but not coarsely, punctured all over. Lateral carinae developed only in the prozona, where they are rounded- VOL.
