Pronotum: Length more than half width, 2.13(1.89-2.28) : 3.92 

 (3.57-4.16); anterior margin deeply and simply emarginate; side 

 margins entire, narrowing from just in front of base, with submarginal 

 row of 14 to 17 setigerous punctures; transverse unpression obsolete 

 to absent, marked by a very irregular band of moderate punctures; 

 anterior lobe with anterior submargin sometimes vaguely impressed, 

 with a row of irregularly spaced punctures, laterally with numerous 

 close-set punctures; posterior lobe impunctate except for a few punc- 

 tures in middle and several in antero-lateral angles. 



Scutellum: Longer than wide, 2.65(2.37-2.79) . -2. 28(2. 08-2.47) ; 

 disc poUshed, with few, mostly wide scattered, sunken punctures 

 becoming finer toward apex. 



Hemelytron: Corium and clavus polished; corium usually with one 

 complete and the basal part of a second row of punctures paralleling 

 claval suture, exocorium punctate for most of its length; mesocorium 

 variously punctured at base and apex and with one complete 

 row and the basal half of a second row of punctures present and 

 paralleling claval suture; clavus with a single, longitudinal row of 

 punctures extending more than half way to apex; costa with five to 

 eight setigerous punctures; membranal suture straight, lateral angle 

 almost rectangular; membrane reaching or very slightly surpassing 

 apex of abdomen. 



Propleuron: Impunctate; prosternal carinae low, acute, 



Mesopleuron and metapleiu-on: As described for subgenus; apex 

 of peritreme fusing with surrounding cuticula; lateral edge of evapora- 

 torimn deeply concave (fig. 106); lateral polished area slightly convex, 

 with several weak, longitudinal rugae. 



Sternites: Polished, roughened laterally by numerous fine, longi- 

 tudinal rugae; sutures finely crenulate. 



Legs: Moderately long, posterior pair modified as in subgeneric 

 description (fig. 148). 



TermJnalia: Genital capsule with distinct, shallow emargination 

 at middle of apical margin; surface with numerous punctures either 

 side of polished midline; gonostylus as illustrated (fig. 261). 



Length of body: 7.57(6.83-7.94). 



Female: Similar to male, usually with fewer pronotal and scutellar 

 punctures and never with modification of posterior legs that occurs 

 in males. 



Head: Length-width ratio, 1.30(1.26-1.39) : 1.84(1.76-1.99); in- 

 terocular width, 1.19(1.15-1.26). Antennal segments: I, 0.39(0.37- 

 0.43); II, 0.49(0.46-0.56); III, 0.48(0.43-0.56); IV, 0.60(0.46-0.68); 

 V, 0.65(0.54-0.71). Labial segments: I, 0.66(0.62-0.70); II, 1.05 

 (0.96-1.16); III, 0.89(0.76-1.03); IV, 0.54(0.50-0.60). 



Pronotum: Length-width ratio, 2.11(1.95-2.28) :3.97(3.78-4.36).
