between ocelli; juga with few to several prominent punctures; ocelli 

 moderate, removed from eyes by a space twice an ocellar width; juga 

 ventrally polished, impunctate; maxillary plate with punctate impres- 

 sion mesad of antennal insertion and punctate along basal margin. 

 Antennal segments: I, 0.36(0.36-0.36); II, 0.60(0.53-0.66); III, 0.56 

 (0.50-0.60); IV, 0.81(0.73-0.86); V, 0.94(0.90-1.00). Bucculae lower 

 than labial II; labium reaching between middle coxae. Labial seg- 

 ments: I, 0.73(0.70-0.76); II, 1.04(0.96-1.10); III, 1.21(1.16-1.23); 

 IV, 0.76(0.73-0.80). 



Pronotum: Length about half width, 2.45(2.38-2.55) :4. 75(4.47- 

 4.92); anterior margin shallowly concave, about two-thirds of basal 

 width; side margins entire, gradually narrowed from base and more 

 abruptly at apical third, with five or six submarginal setigerous punc- 

 tures; transverse impression obsolete to absent, marked by irregular, 

 postmedian band of punctures; anterior lobe with a row of punctures 

 paralleling anterior emargination and several punctures laterally; pos- 

 terior lobe with several punctures medially. 



Scutellum: Length and width equal, 3.01 (2.85-3.12) :3. 01 (2.84- 

 3.12); surface shining, with numerous punctures except across base 

 and apex. 



Hemelytron : Corium and clavus very weakly alutaceous; exocorium 

 abundantly punctate for full length; mesocorium with two complete 

 rows of punctures paralleling claval suture, and numerous punctures 

 at base and apex; clavus with several punctures in addition to longi- 

 tudinal row; costa with one setigerous puncture; membranal suture 

 weakly concave, lateral angle acute; membrane reaching apex of 

 abdomen, slightly longer than basal width. 



Propleuron: Impunctate except along anterior margin and in 

 depression; prosternal carinae very low, tliick, blunt. 



Mesopleuron: Evaporatorium reaching side margin of segment; 

 lateral shining area rugopunctate. 



Metapleuron: Evaporatorium slightly concave laterally; lateral 

 area impunctate. 



Sternites: Polished, impunctate. 



Terminalia: Apical margin of genital plate with deep U-shaped 

 notch (fig. 175), surface impunctate; gonostylus as illustrated (fig. 

 268). 



Length of body: 8.93(8.50-9.26). 



Female: Based on two specimens. Similar to males, but surface 

 of head flattened or concave only on juga. 



Head: Length-width ratio, 2.32(2.10-2.55) :4. 63(4.23-5.00) ; inter- 

 ocularwidth, 1.49(1.43-1.56). Antennal segments: 1,0.35(0.35-0.36); 

 11,0.58 (0.53-0.63); III, 0.56(0.50-0.63); IV, 0.82(0.73-0.92); V, 0.93
