femur (fig. 163), two features which appear to be unique with this 

 species.

 usually paler.

Head: Length three-fourths width, 0.42(0.41-0.43) :0.56(0.53-0.60) ; 

 interocular width, 0.32(0.31-0.34); clypeus slightly surpassing juga; 

 latter with four marginal pegs becoming finer toward eye; surface, 

 except clypeus, roughly punctate. Antennal segments: I, 0.10(0.07- 

 0.13); II, 0.02(0.02-0.03); III, 0.23(0.21-0.25); IV, 0.23(0.23-0.25); 

 V, 0.23(0.21-0.25). Labium reaching bases of posterior coxae. 

 Labial segments: I, 0.18(0.17-0.20); II, 0.26(0.26-0.27); III, 0.28 

 (0.26-0.30); IV, 0.23(0.20-0.26). 



Pronotum: Length more than two-thirds width, 0.91(0.84-1.03): 

 1.32(1.24-1.50); anterior margin moderately concave; lateral margin 

 faintly concave on basal third ; transverse impression distinct, marked 

 by regular row of coarser, closer punctures; anterior lobe with coarse 

 punctures in three or four rows laterally and subapically, and along 

 midline and scattered over calli; posterior lobe, except umbones, 

 abundantly punctate. 



Scutellum: Length-width ratio, 0.59(0.53-0.66) :0.65(0.61-0.72). 



Hemelytron: Mesocorium discally with single, irregular row of 

 fine punctures; exocorium punctate for full width. 



Propleuron : Prosternal carmae almost as high as labial II, abruptly 

 terminated posteriorly. 



Legs: Anterior femur ventrally with submedian spine very short, 

 simple; anterior tibia with two prominent angulations or spines on 

 lower edge (as in fig. 132); posterior femur ventrally with subapical 

 spine very long, more than third length of posterior tibia (fig. 164). 



Terminalia: Gonostylus as illustrated (fig. 295). 



Length of body: 2.30(2.08-2.66). 



Female: Similar to male, but lacking secondary sexual modifica- 

 tions; posterior femur with small, oblique spine ventrally near apex 

 (fig. 163). 



Head: Length-width ratio, 0.43(0.43-0.44): 0.54 (0.53-0.55); inter- 

 ocular width, 0.33(0.33-0.33). Antennal segments: I, 0.10(0.09- 

 0.12); II, 0.02(0.02-0.02); III, 0.21(0.20-0.23); IV, 0.21(0.20-0.23); 

 V, 0.22(0.21-0.24). Labial segments: I, 0.16(0.16-0.17); II, 0.25 

 (0.23-0.28); III, 0.33(0.33-0.33); IV, 0.25(0.25-0.27). 



Pronotum: Length-width ratio, 0.73(0.70-0.74): 1.24(1.23-1.26). 



Scutellum: Length-width ratio, 0.51 (0.50-0.53) :0. 56(0. 56-0.57). 



Length of body: 2.19(2.15-2.28).
