Thorax 448-486 (average 469) [i. long. 



Prothorax. Pronotal ridge strong, but medially interrupted l>v weak sclerotization. Lateral 

 pronotal sclerites small, with an occasional fleshy lateral pronotal seta occurring immediately 

 behind them. Medial pronotal setae and pores absent Post-tergites very small, if present ; derm 

 irregularly striated, without setae- Pleural structures typical of the family Sternum with 

 strong transverse ridge, usually narrowed medially ; median rid^e only represented on anterior

 Mesopostphragma short, with shallow emargination. Mesopleuron. Mesopleural ridge strong, 

 but becoming weaker immediately above coxa! articulation ; pleural apophysis and pleural 

 wing process well developed, the latter connected with episternum by a narrow hasalare.
