ternal and inferior margin sparsely serrulate, lower surface with a

 surface narrowly flattened, lower margins slightly expanded basally 

 and provided with several dentiform serrations, lower surface with the 

 weak median carina elevated apically and bearing several rather 

 slight dentiform processes, genicular lobes acute. Posterior femora 

 considerably exceeding the pronotum and mesonotum in length, 

 general structure identical with that of the median femora except 

 that the external inferior margin alone is expanded and developed into 

 but ofie dentiform serration; tibiae slightly exceeding the femora in 

 length, pentagonal in section, median inferior carina evenly elevated 

 in the proximal portion.
