510 Mr. G. Meade- Waldo's revision of the species of 



Head and thorax ferruginous, the abdomen black with a broad 

 yellow line extending along the whole length; terminal segment 

 ferruginous. 



Clypeus convex rather longer than broad, narrowly produced 

 towards the apex, which is armed with two small teeth. Anterior 

 margin of pronotum curved, widening towards tegulae ; scutellum 

 Hat, not raised above mesonotum, postscutellum truncate poste- 

 riorly, transverse ; upper angles of median segment acute, separated 

 from sides of the postscutellum by a distinct fissure, truncation of 

 median segment concave. 



Basal segment of abdomen broad and rounded, as wide as second 

 at base. Head and thorax coarsely and evenly punctured, abdomen 

 more finely punctured. Wings with the basal third flavohyaline, 

 and the apical tAvo-thirds fuscous. 



(J differs onlj'^ in having the clypeus and mandibles and a large 

 interantennal mark, yellow. 3 $ ?, 1 J.

 (type) and J. J. Simpson); Gambia, 26. iii. 1911 (J. J. 

 Simpson) $, and " West Africa " ^. 



The superficial resemblance between this species and the 

 well-known Odijnerus lateralis, Fab. {trnncatus, Sauss.), is 

 very striking. The dift'erences in the structure of the 

 postscutellum and median segment render their discrimina- 

 tion easy.

I can find no description of 0. broomi, but the type 

 specimen in the British Museum is certainly referable to 

 0. euryspilus, the type of which was a $. Both specimens 

 are from Cape Colony; there are also specimens (1 (^, 1 9) 

 from Willowmore, Cape Colony {Dr. H. Brauns), in the 

 collection.
