Eyes distinctly converging below, the hinder ocelli separated 

 from each other by Ibe same distance as they are from the eyes; 

 they are distinctly, but very closely punctured ; a narrow furrow, 

 widened above, runs down its centre; apex of clypeus not quite 

 transverse. Pronotum broadly rounded, closely punctured, tbe 

 mesonotum more strongly, but not so closely punctured; tbe 

 scuLellum is more weakly and closely punctured on the basai half, 

 the metanotum is as strongly, but much more closely punctured 

 and with a shallow, indistinct furrow down its centre, this furrow 

 becoming widened towards the end. Pleuras roughly but not 

 strongly or closely punctured. 



Cornes near to S. albisectus Lep. and S. Sjôstedtii Cam. ; it has the 

 black abdominal pétiole of the latter; Spliex Sjôstedtii differs in 

 having oui y the dilated apical part of the abdominal pétiole red, 

 the 2 nd segment being entirely black ; 2'" 1 and 3 n1 white bands are not 

 curved and the 2 ml and following ventral segments are black; the 

 2 nd and 3 rrl transverse cubital nervures are straight, not roundly 

 curved, and the apical abscissa of the radius is straight, oblique, 

 not broadly rounded. There are 3 stout teeth on the claws. 



It is quite possible that a good séries of spécimens from varions 

 parts of Africa would show that 8. albisectus, S. Sjôstedtii and 

 S. curvilineatus, were forms of one species. 



The spécimens I hâve before me seem easily enough separated, 

 but not by very strong or distinctive characters; in size and form 

 they are very similar.

A species widely distributed in the Southern Palaearctic and 

 Ethioptian ZoolOgical Régions. It varies considerably in coloura- 

 tion, c. g , the prothorax may be entirely black or red ; the 

 antennal scape may be black or red and the amount of red on the 

 abdomen and legs varies.
