Scutellum: Longer than wide, 2.11(2.02-2.30) :2.02(1.89-2.15); disc 

 shining, with few widely scattered punctures, impunctate on basal 

 fourth and apex. 



Hemelytron: Clavus and corium alutaceous; clavus with two 

 irregular, confused rows of punctures; mesocorium with one complete 

 row and one incomplete row of punctures paralleling claval suture, 

 discally with punctures sparse and scattered or numerous; exocorium 

 punctured similarly to disc of mesocorium; costa with three or four 

 setigerous punctures; membranal suture nearly straight, lateral angle 

 sometimes weakly produced; membrane longer than basal width, just 

 reaching apex of abdomen. 



Propleuron: Finely alutaceous, punctured sparsely in depression 

 and more abundantly anterior to acetabulum; prosternal carinae less 

 than half as high as labial II. 



Mesopleuron: Evaporatorium reaching into posterolateral angle 

 but not to lateral margin of segment; lateral area with a few coarse 

 punctures. 



Metapleuron: Apex of peritreme fused with surrounding cuticula 

 (as in fig. 106), not abruptly terminated; evaporatorium with lateral 

 margin deeply concave, C-shaped, lateral area impunctate, extended 

 almost to apex of peritreme. 



Legs: Not specially modified. 



Sternites: Shining, becoming more distinctly alutaceous laterally; 

 laterally also with several longitudinal rugae. 



Terminalia: Genital capsule shining, distinctly punctured in lateral 

 angle, with broad submarginal depression laterally, apical margin 

 entire, almost straight; gonostylus as illustrated (fig. 273). 



Length of body: 6.22(5.97-6^66). 



Female: Very similar to male.
