0.19(0.18-0.20) ; III, 0.40(0.39-0.41) ; IV, 0.36(0.35-0.38) ; V, 0.39(0.39 

 0.40). Bucculae about two-thirds as high as labial II; labium reach- 

 ing between middle coxae. Labial segments: I, 0.52(0.52-0.52); II, 

 0.85(0.82-0.89); III, 0.75(0.73-0.77); IV, 0.44(0.42-0.47). 



Pronotum : Length about one-half width, 1.55(1.55-1.56) :3. 17(3. 15- 

 3.20); anterior margin simply, shallowly emarginate; lateral margin 

 straight on basal two-thirds, incurved apically, with 11 to 12 setiger- 

 ous punctures submarginally; transverse impression obsolete to mod- 

 erately distinct, marked on lateral third by row of distinct, close-set 

 punctures; anterior lobe impunctate except for a few obsolete, minute 

 punctures laterally; posterior lobe with very few, widely scattered 

 punctures on anterior half. 



Scutellum: Length less than width, 1.82(1.80-1.84) :2.01(1.99-2.04); 

 disc shining, with fine punctures scattered between sparse, moderately 

 coarse punctures. 



Hemelytron: Clavus and corium shining, both with numerous fine 

 but distinct punctures, those near claval suture on corium forming a 

 single line of coarser punctures; costa with about ten setigerous punc- 

 tures; membranal suture straight, lateral angle not prolonged; mem- 

 brane longer than basal width, surpassing apex of abdomen. 



Propleuron: Polished, impunctate; prosternal carinae sharp, less 

 than one-fourth as high as labial II. 



Mesopleuron: Lateral area impunctate. 



Metapleuron: Lateral margin of evaporatorium concave; lateral 

 area convex, impunctate. 



Legs: Hind tibia minutely denticulate proximad of obtuse, sub- 

 basal emargination on postero ventral margin; spines of that margin 

 longer and much finer than those of dorsal margin. 



Sternites: Polished, with few scattered punctures on lateral third. 



Terminalia: Genital capsule with patch of numerous minute punc- 

 tures either side of midline, lateral angles impressed and rugulose; 

 apical margin entire; gonostylus as illustrated (fig. 236a). 



Length of body: 5.69(5.58-5.80). 



Female: Similar to male, but without subbasal angulation on 

 postero ventral margin of hind tibia. 



Head: Length-width ratio, 1.02(0.98-1.04): 1.36(1.32-1.44); inter- 

 ocular width, 0.91(0.91-0.92). Antennal segments: I, 0.29(0.28-0.31); 

 II, 0.33(0.33-0.33); III, 0.40(0.38-0.42); IV, 0.38(0.38-0.38); V, 

 0.40(0.37-0.42). Labial segments: I, 0.62(0.60-0.66); 11,0.89(0.88- 

 0.90); III, 0.76(0.73-0.79); IV, 0.31(0.30-0.32). 



Pronotum: Length-width ratio, 1.66(1.60-1.74):3.64(3.44-3.76). 



Scutellum: Length-width ratio, 2.15(2.00-2.40) :2. 16(2.04-2.36). 



Length of body: 5.64(5.52-5.80).
