South African Coleopterous Fauna. 309 



articulis tribus vel quatuor penultimis conicis, aequalibus, ultimo 

 praecedenti latior et dimidio longior, caeteris gracilibus ; prothorax 

 sub-parallelus vel antice nonnihil attenuatus, basi apiceque haud 

 sinuatus ; scutellum breve, triangulare ; elytra antice prothorace 

 haud latiora, ad medium magis minusve ampliata, sub-convexa, apice 

 dehiscentia, lateraliter marginata ; epipleura levia, angusta, apice 

 latiuscula ; pedes longi, graciles, tarsis subtus dense longeque ciliatis, 

 femoribus anticis ante apicem dente valida infra armatis ; prosternurn 

 processu longo, acuto, niesosternum antice triangulariter incisum. 



Differs from Psorodes not only in general facies but also in the 

 shape of the antennae, which are shorter, and the five ultimate joints 

 of which are thickened instead of being of equal width, and nearly 

 filiform ; in Psorodes the mesosternum is not incised.
