ceous, with few weak punctures toward base. Antennal segments: 



I, 0.46(0.43-0.50); II, 0.68(0.66-0.71); III, 0.62(0.59-0.68); IV, 

 0.94(0.90-1.00) ; V, 1.00(0.94-1.05). Bucculae about as high as labial 



II. Labial segments: I, 0.71(0.70-0.73); II, 1.25(1.16-1.35); III, 

 1.11(1.03-1.20); IV, 0.61(0.60-0.63). 



Pronotum: Length more than half width, 2.75(2.40-3.00) : 5.08 

 (4.61-5.53) ; anterior margin broadly and rather shallowly emarginate; 

 side margins entire, narrowing from base or from immediately anterior 

 to base, with submarginal row of seven or eight setigerous punctures; 

 transverse impression obsolete to absent, submedian, marked by 

 a broad band of moderate punctures; remainder of surface virtually 

 impunctate except for several punctures on middle of posterior lobe. 



Scutellum: Longer than wide, 3.39(3.02-3.70) :3. 13 (2.83-3.60) ; 

 surface shining, or faintly alutaceous, with several irregularly scattered 

 punctures discally. 



Hemelytron: Corium and clavus alutaceous; former with distinct 

 punctures restricted to a single complete row paralleling claval suture 

 and basal third of a second row; clavus with a single longitudinal row 

 of punctures becoming evanescent posteriorly; costa with none to 

 three setigerous punctures; membranal suture faintly sinuate near 

 lateral angle, latter slightly acute. 



Propleuron: Depression with numerous coarse, close-set punctures 

 ventrally ; prosternal carinae low, blunt. 



Mesopleuron : As described for genus. 



Metapleuron: Peritreme abruptly terminated apically (as in figure 

 107) ; evaporatorium with lateral edge slightly concave; lateral shining 

 area tumid, impunctate or with a few moderate punctures. 



Sternites: Impunctate, alutaceous; sutures finely crenulate. 



Legs: Long; posterior tibia gently curved, with prominent angula- 

 tion at basal fourth of posteroventral margin, emargination basad of 

 this finely crenulate. 



Terminalia: Genital capsule with apical margin slightly emarginate 

 medially, surface punctured along base and apex; gonostylus as il- 

 lustrated (fig. 260). 



Length of body: 9.62(8.58-10.46). 



Female: Similar to males except for generally fewer pronotal 

 punctures and the absence of the tibial modification described above. 



Head: Length-width ratio, 1.45(1.43-1.49) :2.08(2.02-2.17); inter- 

 ocular width, 1.25(1.22-1.31). Antennal segments: I, 0.50(0.47- 

 0.56); II, 0.68(0.64-0.76); III, 0.63(0.60-0.68); IV, 0.91(0.86-1.00); 

 V, 0.97(0.93-1.03). Labial segments: I, 0.78(0.71-0.90); II, 1.30 

 (1.30-1.33); III, 1.06(0.98-1.13); IV, 0.64(0.61-0.70). 



Pronotum: Length-width ratio, 2.78(2.68-3.00) :5.03(4.79-5.42). 



Scutellum: Length-width ratio, 3.41(3.17-3.88) :3.00(2.74-3.45).
