laterally not quite coalescent above, emitting recurrent nervure from 

 its centre. Length, 14 mm. 



The type and co-type were taken at Salisbury, in Southern Rhodesia, 

 during 1915 by D. Dodds, and at Salisbury in September, 1913. 



EUPALAMUS, Wesm. 

 Nouv. Mem. Ac. Brux. 1844, p. 13. 



This originally ill-differentiated genus is well characterised by Prof. 

 Thomson (Ann. Soc. France, 1886, p. 11) : Cheeks always quite short 

 and in ? sub-buccate, mandibles stout and clypeus apically truncate 

 with labrum distinctly exserted ; face short and the confluent antennal 

 scrobes large and glittering ; vertex not broad. Flagellum of ? 

 centrally dilated, in its seventh to fifteenth joints with elevated 

 carinae. Ai'eola longer than broad, and coxal area distinct ; scutellum 

 not transverse. Petiole gently and equally curved throughout ; post- 

 petiole not aciculate, somewhat smooth or rugulose, with its central 

 area twice as broad as the lateral ones ; gastrocoeli small and sub- 

 rugulose, thyridii far from base and not large. Posterior tibiae and 

 femora stout. Thorax and abdomen somewhat deplanate. 



EUPALAMUS CONVEXIUS, sp. nov. 



? only. A stout and dull black species with the palpi, a central 

 flagellar band, and inner side of the front tibiae, white ; face, cheeks, 

 frontal orbits, underside of scape, a broad auteradical line, small 

 callosities below radices, a discal mesonotal mark and whole of both 

 the scutellum and postscutellum, sanguineous-red (perhaps stramineous 

 in nature) ; front tarsi iufuscate. Head posteriorly not broad ; face 

 closely and coarsely, frons closely and evenly, punctate ; antennae 

 abruptly attenuate at extreme apices, with the peiiultima.te joint and 

 that preceding it (perhaps accidentally) deeply excavate. Thorax with 

 nonotauli; metanotal costulae strong; areola elongate, subglabrous, 

 nitidulous and but indefinitely separated from the strongly punctate, 

 pilose and strongly discreted petiolar area. Scutellum large, strongly 

 convex, glittering and very conspicuous. Abdomen fusiform and 

 immaculate with the petiole narrow and postpetiole abruptly explanate, 

 finely rugulose, with prominent spiracles. Legs normal and coxae 

 simple ; wings broad and a little clouded ; costa, stigma and nervures 

 black ; lower basal nervure but slightly postf urcal ; areolet pentagonal, 

 not coalesceut above, emitting recurrent subceiitrally. Length, 13 mm. 

 The type occurred at Bulwer in Natal during 1914 to W. Hay- 

 garth.
