 oblique^ ocelli almost as near lo eyes as to each other ; pro- 

 notum about as long as head, its lateral margins moderately 

 convex, its ])Osterior angles widely ampliated ; mesonotum 

 (including cruciform elevation) longer than pronotum ; abdo- 

 men moderately inflated, attenuated posteriorly, dorsally 

 medially ridged, longer than space between apex of head 

 and base of cruciform elevation ; tympana entirely exposed ; 

 opercula in male extremely small, leaving the cavities 

 almost entirely exposed ; anterior femora only moderately
