Genus SESIOPLEX Viereck 



This genus was originally based on the single character of the de- 

 pressed first abdominal segment, by which character it was said to 

 differ from Campoplex Gravenhorst { = Ormogu8 Foerster). 



In his key to genera of the Campopleginae - Viereck ascribed sev- 

 eral other characters to the genus, and (p. 177) assigned to it four 

 species besides the genot3'pe. Of these heliae (Ashmead) is a Saga- 

 ritis Holmgren. The other two previously described species, depres- 

 sus Viereck and validus (Cresson), will run in Schmiedeknecht's 

 (Opusc. Ichn.) key to Tranosema Foerster, failing to stop at 

 ( Oinoryxis) = Campoplex because of the more or less distinctly broken 

 nervellus. The same character prevents their running to Eulimneria 

 Schmiecleknecht.
