tinctly impressed across full width, except sometimes more weakly 

 so medially, marked by regular row of distinct, close-set punctures; 

 subapical impression moderate, with numerous coarse and minute 

 punctures; anterior lobe laterally with mixture of numerous coarse 

 and minute punctures; posterior lobe with numerous widely separated 

 minute punctures over full width and few coarse ones medially and 

 laterally. 



Scutellum: Longer than broad, 1.82(1.75-1.89): 1.58(1.49-1.62); 

 shining, with numerous scattered minute punctures, with several 

 coarse ones discally but not across base or apex. 



Hemelytron: Clavus and corium polished; clavus polished, with 

 one complete and sometimes a second partial row of coaree punctures ; 

 mesocorium with two complete rows of punctures paralleling claval 

 suture and finer ones scattered widely over disc; exocorium punctured 

 full length, punctures coarser and sparser on mesal half; membranal 

 suture straight, lateral angle not or faintly produced; membrane 

 longer than basal width, reaching or just surpassing apex of abdomen. 



Propleuron: Polished, punctate in depression and anterior to 

 acetabulum; prosternal carinae less than half as high as labial II. 



Mesopleuron: Evaporatorium not inten^upted; lateral area im- 

 punctate, with obsolete oblique rugae. 



Metapleuron: Peritreme abruptly terminated apically; lateral 

 margin of evaporatorium weakly concave; lateral area impunctate. 



Sternites: Shining, with very minute punctures scattered over 

 full width; moderatelj^ rugopunctate in spiracular area. 



Legs: Not specially modified. 



Terminalia: Genital capsule more densely punctate laterally, 

 apical margin broadly and very shallowly emarginate medially; 

 gonostylus as illustrated (fig. 277).
