Mesonotum with distinct sharp lateral keel on each side. 

 Third antennal seoment a little longer than broad. 



The above chaoacters, by which Verhoeff distinguishes his 

 genus CtenisoJabis^ for the single species Ct. togoensis^ are 

 common to B. chilensis, Blanch., which is the type of Brachy- 

 lahis. Consequently the foimer genus falls as a synonym. 



BracJiylahis in its true sense also includes B. nigra, Scudd., 

 B. maJgacha, Borm., B. caudelli, sp. n. (^vide infra), 

 B. hifoveolata, Bob, and B. voeltzkoioi, sp. n. [vide infra).
