labium reaching between posterior coxae. Labial segments: I,

Pronotum : Length more than half width, 2.65(2.58-2.85) :4. 56(4.41- 

 5.10); lateral margins straight on basal two-thirds, with submarginal 

 row of 12 to 14 setigerous punctures; transverse impression moder- 

 ately impressed, marked by rather regular, medially interrupted row 

 of coarse punctures; anterior lobe with broad, shallow, subapical im- 

 pression, with punctures confined to subapical band and lateral patch; 

 posterior lobe with several coarse punctures medially and few others 

 scattered elsewhere. 



Scutellum: Length subequal to, slightly less than, or slightly more 

 than width, 3.23(3.15-3.45) :3. 13(2.86-3.31); disc with few to several 

 widely scattered, coarse, sunken punctures. 



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

 median row of punctures; mesocorial punctation moderate, abundant 

 except along radial vein, forming two rows paralleling claval suture, 

 outer one usually incomplete; costa with sLx to eight setigerous 

 punctures; membrane distinctly surpassing apex of abdomen. 



Propleuron: Shining, with few fine punctures laterad of acetabulum 

 and few coarse punctures in depression. 



Mesopleuron (fig. 109) : Lateral margin of evaporatorium bisinuate; 

 lateral area shining, impunctate. 



Legs: Posterior tibia (fig. 142) with greatest diameter equalling 

 that of anterior tibia (fig. 123), latter with seven or eight stout, 

 flattened, blunt spines arising from blackened elevations on dorsal 

 margin. 



Sternites: Shining, polished or faintly alutaceous, rugulose in 

 spiracular area; setigerous punctures on III to VIII prominent, with 

 long setae. 



Terminalia: Genital capsule shining, with scattered fine punctures; 

 gonostylus as illustrated (fig. 244). 



Length of body: 7.63(6.73-7.94). 



Female: Very similar to male in shape, punctation, and subapical 

 pronotal impression; measurements somewhat larger, especially of 

 labial segment 11. 



Head: Length-width ratio, 1.49(1.43-1.56) :2. 16(2.08-2.24); inter- 

 ocular width, 1.33(1.23-1.43). Antennal segments: I, 0.41(0.36- 

 0.46); II, 0.28(0.23-0.33); III, 0.45(0.43-0.50); IV, 0.40(0.38-0.43); 

 V, 0.47(0.40-0.53). Labial segments: I, 0.90(0.83-1.00); II, 1.21 

 (1.13-1.33); III, 1.07(1.03-1.13); IV, 0.97(0.93-1.04). 



Pronotum: Length-width ratio, 2.75(2.71-2.97) :4.76(4.46-5.09). 



Scutellum: Length-width ratio, 3.29(3.14-3.45) :3.30(3.30-3.30). 



Length of body: 7.75(7.33-7.97).
