 (1.06-1.36); interocular width, 0.75(0.66-0.84); anterior outline an 

 elongate semicircle, juga little longer than clypeus and almost con- 

 tiguous anterior to it; surface shining, usually with weak, radiating 

 rugae; jugum with one setigerous puncture submarginally anterior 

 to eye; ocelli moderate, removed from eye by space almost twice 

 transverse ocellar width; jugum vcntrally and maxillary plate (except 

 basally) shining, impunctate. Antennal segments: I, 0.25(0.23-0.29) ; 

 II, 0.'21 (0.21-0.23); III, 0.32(0.30-0.37); IV, 0.37(0.36-0.40); V, 

 0.47(0.46-0.52). Bucculae about half as high as labial II, evanescent 

 posteriorly; labium extended between middle coxae. Labial seg- 

 ments: I, 0.36(0.35-0.43); II, 0.61(0.51-0.66); III, 0.50(0.44-0.56); 

 IV, 0.37(0.32-0.40). 



Pronotum: Length more than half width, 1.40(1.19-1.56) :2. 57 

 (2.13-2.92); anterior margin shallowly, doubly emarginate; lateral 

 margin straight to weakly convex on basal two-thirds, with sub- 

 marginal row of four or five setigerous punctures; transverse impres- 

 sion distinct across full width, weaker at middle, marked by medially 

 interrupted row of punctures; anterior lobe impunctate except for 

 occasional small punctures laterally, median line impressed from sub- 

 apical line to between calli; posterior lobe with few scattered punc- 

 tures on anterior half of middle area. 



Scutellum: Length equal to or less than width, 1.46(1.24-1.64): 1.48 

 (1.25-1.71); disc shining, with several widely scattered punctures. 



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

 punctures; corium obsoletely or not punctate except for punctures in 

 one complete row and usually one partial row paralleling claval 

 suture; costa with one setigerous puncture; membranal suture straight, 

 lateral angle not produced; membrane longer than basal width, 

 surpassing apex of abdomen. 



Propleuron: Shining, impunctate or with few coarse punctures in 

 depression; prosternal carinae less than half as high as labial II. 



Mesopleuron: Evaporatorium reaching lateral margin; lateral area 

 shining, obtusely rugose. 



Metapleuron: Lateral margin of evaporatorium feebly concave; 

 lateral area shining, impunctate. 



Legs: Posterior tibia without subbasal angulation ventrally, with 

 four spines on posteroventral margin. 



Sternites: very finely alutaceous, impunctate. 



Terminalia: Genital capsule with scattered fine punctures more 

 abundant in lateral impressed areas, apical margin straight or slightly
