This genus is also monotypic, and was erected for the reception 

 of a species which has been referred to CheJisochella and Chelisoches. 

 It was included by Yerhoeif in the former, but probablv w'thout 

 seeing specimens, since it has not the entire keel on the elytra, 

 which is the essential character of that genus as defined by Verhoeff 

 himself.
