coxae. Labial segments: I, 0.23(0.21-0.24); II, 0.42(0.40-0.45); III, 

 0.30(0.28-0.32); IV, 0.22(0.21-0.24). 



Pronotum: Length more than half of width, 0.85(0.81-0.92): 

 1.58(1.51-1.67); anterior margin shallowly, simply emarginate; lat- 

 eral margin straight on basal half or more, submarginal row of five 

 setigerous punctures; transverse impression postmedian, distinctly 

 and almost equally depressed across full width, not marked by special 

 row of punctures; anterior lobe with coarse, crowded punctures lat- 

 erally and subapically, medially with fine punctures, calli with few 

 minute punctures; posterior lobe shining, with numerous moderate 

 punctures scattered nearly or quite to hind margin. 



Scutellum: Length greater than width, 1.13(1.06-1.20) :0. 92(0.86- 

 0.97) ; shining, with numerous well-separated punctures over surface 

 except in basal angles. 



Hemelytron: Clavus and corium shining, clavus with 1% rows of 

 punctures; mesocorium with two complete rows of punctures paral- 

 leling claval suture, elsewhere punctation sparse, fine, becoming little 

 coarser towards base; exocorium punctate similar to mesocorium; 

 costa thin, weakly reflexed on basal half, with one setigerous puncture 

 dorsally near base; membranal suture straight, lateral angle not pro- 

 duced; membrane little longer than basal width, just attaining apex 

 of abdomen. 



Propleuron: Anterior convexity longitudinally rugopunctate; de- 

 pression with few coarse punctures; prosternal carinae about as high 

 as labial II, anterior margin long, vertical, produced ventrall}^ as 

 small, semicircular lobe. 



Mesopleuron: Evaporatorium reaching into posterolateral angle, 

 not attaining lateral margin of segment; lateral area shining, in part 

 rugopunctate. 



Metapleuron: Terminal modification of peritreme large, semicir- 

 cular, reaching almost to lateral margin of evaporatorium; lateral 

 area with several coarse punctures. 



Legs: Anterior tibia with five or six stout spines dorsally. 



Sternites: Polished, minutely punctate, with several weak rugae 

 laterally near spiracular area. 



Terminalia: Genital capsule shining, punctures becoming dense 

 laterally, apical margin wealdy decurved; gonostylus as illustrated 

 (fig. 213). 



Length of body: 3.33(3.16-3.55). 



Female : Similar to male, most measurements averaging larger. 



Head: Length-width ratio, 0.65(0.63-0.67): 0.85(0.83-0.87); inter- 

 ocular width, 0.53(0.51-0.56). Antennal segments: I, 0.18(0.16- 

 0.22); II, 0.20(0.18-0.23); III, 0.24(0.23-0.25); IV, 0.30(0.30-0.33);
