punctures (usually with fine ones intermingled) becoming finer 

 apically. 



Hemelytron: Clavus and corium polished; clavus with one com- 

 plete row of punctures and basal part of another; mesocorium with 

 two complete rows of punctures paralleling claval suture, disc with 

 numerous distinct punctures becoming coarser basally; exocorium 

 irregularly but mostly more densely punctate than mesocorium; 

 costa wide, thin, gently reflexed to form a shallow, open trough on 

 basal third, without setigerous punctures; membranal suture straight, 

 lateral angle not produced, membrane longer than basal width, 

 reaching apex of abdomen, 



Propleuron: Anterior convexity with numerous, close, anastomos- 

 ing rugulae; with few coarse punctures in depression; prosternal 

 carinae not as high as labial II, convexly terminated posteriorly. 



Mesopleuron (fig. 96) : Evaporatorium reaching almost to lateral 

 margin of segment; lateral area with several coarse punctures. 



Metapleuron (fig. 96): Terminal modification of peritreme large, 

 reaching almost to lateral margin of evaporatorium; lateral area with 

 band of numerous punctures near evaporatorium. 



Legs : Anterior tibia with six or seven stout spines dorsally. 



Sternites: Medially shining and minutely punctate, lateral fourth 

 with small punctures and numerous short, longitudinal rugulae. 



Terminalia: Genital capsule shining, almost uniformly punctate, 

 apical margin straight; gonostylus as illustrated (fig. 215).
