 fourth inclusive in length. Median femora almost equal to the meta- 

 notum (with median segment) in length, external inferior margin 

 armed apically with two dentiform processes; median tibia? slightly 

 shorter than the femora, apically with a slight tumidity, the inferior 

 median carina with a low triangular basal expansion; metatarsi not 

 quite equal to the remaining tarsal joints in length, not dilated; fifth 

 tarsal joint about equal to the second to fourth joints inclusive. Pos- 

 terior femora reaching to the base of the third abdominal segment, 

 slightly compressed, internal inferior margin apically with two denti- 

 form processes, internal genicular lobes spiniform; posterior tibia> 

 equal to five-sixths the length of the mesonotum, slightly tumid at the
