half of the head will separate this species from all others within the 

 subgenus. 



Description. — Male: Oval, somewhat parallel-sided. 



Head: Length two-thu-ds width, 1.22(1.13-1.31): 1.80(1.71-1.96); 

 interocular width, 1.20(1.10-1.26); anterior outline a full semicu-cle, 

 juga longer than and nearly or quite contiguous anterior to clypeus; 

 surface shining, with numerous distinct, radiating rugae; jugum de- 

 pressed medially with four to six coarse, setigerous punctures sub- 

 marginally, without short, stout pegs; ocelli small, situated well be- 

 hind line connecting posterior margins of eyes, removed from eyes by 

 about three times a transverse ocellar width; jugum ventrally shining, 

 impunctate; maxillary plate impunctate, alutaceous on basal half. 

 Antennal segments: I, 0.39(0.33-0.43); II, 0.46(0.43-0.53); III, 

 0.52(0.46-0.56) ; IV, 0.65(0.60-0.70) ; V, 0.70(0.69-0.73). Bucculae as 

 high as labial II, obliquely terminated posteriorly; labium reaching 

 between middle coxae. Labial segments: I, 0.55(0.53-0.57); II, 

 1.00(0.88-1.07); III, 0.83(0.71-0.93); IV, 0.52(0.46-0.58). 



Pronotum: Length more than half width, 2.22(2.08-2.37) : 3.98 (3.78- 

 4.16) ; anterior margin moderately, doubly emarginate; lateral margin 

 entire, broadly and shallowly curved, with ten submarginal setigerous 

 punctures; transverse impression obsolete to absent, marked by very 

 irregular row of scattered punctures; anterior lobe impunctate except 

 for lateral patch of about one dozen coarse punctures with minute 

 punctures interspersed; posterior lobe with few moderate punctures 

 medially and laterally. 



Scutellum: Length greater than width, 2.67(2.47-2.86) :2.40(2.27- 

 2.58); disc polished, with a number of irregularly scattered large 

 punctures. 



Hemelytron: Clavus and corium shining; clavus with one row of 

 punctures; mesocorial surface slightly uneven, punctures in one row 

 paralleling claval suture and closely set on basal half, apically the 

 punctures are much finer and sparser; exocorium obsoletely to dis- 

 tinctly punctate for full length; costa with two to five setigerous 

 punctures; membranal suture straight, lateral angle distinctly pro- 

 duced; membrane longer than basal width, distinctly surpassing 

 apex of abdomen. 



Propleuron: Shining, punctate ventrally in depression and anterior 

 to acetabulum; prosternal carinae much less than half the height of 

 labial II. 



Mesopleuron and metapleuron: Similar to figure 106, but peritreme 

 abruptly terminated apically. 



Legs: Posterior femur with numerous small tubercles on ventral 

 face; posteroventral margin of hind tibia with a finely crenulate basal 

 emargination and a strong angulation distad of it (fig. 153).
