Diagnosis. — The small size (body length 3.7-4.5) and the presence 

 of two setigerous punctures subapically on the clypeus will mark this 

 species from its congeners. 



Description. — Male: Elongate-oval, costa subparallel on basal 

 half. 



Head: Length almost two-thu-ds width, 0.74(0.71-0.81) : 1.10(1.02- 

 1.16) ; interocular width, 0.09(0.63-0.73) ; anterior outline semicircular, 

 clypeus as long as juga, narrowed apically and with two subapical 

 setigerous punctures; jugum with a complete, submarginal row of 

 setigerous punctures bearing a row of stout, blunt pegs and few hair- 

 like setae between; surface shining, with few distinct, obHque rugae, 

 punctation becoming coarser and more abundant towards margins; 

 ocelli well developed, separated from eyes by space nearly twice 

 transverse ocellar width; jugum ventrally and maxillary plate, except 

 basally, polished, knpunctate. Antennal segments: I, 0.21(0.16-0.24) ; 

 II, 0.18(0.16-0.20); III, 0.24(0.23-0.26); IV, 0.27(0.26-0.30); V, 

 0.34(0.33-0.36. Bucculae almost as high as labial II; labium 

 reaching between middle coxae. Labial segments: I, 0.37(0.35-0.40); 

 II, 0.52(0.50-0.61); III, 0.42(0.41-0.43); IV, 0.34(0.33-0.36). 



Pronotum: Length about half width, 1.17(1.10-1.21) :2.27(2. 11- 

 2.40); anterior margin deeply, doubly emarginate; lateral margins 

 entire, straight on basal half, with submarginal row of seven to ten 

 setigerous punctures; transverse impression moderately impressed, 

 obsolete medially, marked by regular, medially interrupted row of 

 punctures; punctation of anterior lobe restricted to broad lateral 

 area and subapical line; posterior lobe with scattered fine and coarse 

 punctures. 



Scutellum: Length little greater than width, 1.46(1.36-1.56) : 1.40 

 (1.29-1.49); polished; almost impunctate across base, discally with 

 numerous scattered punctures becoming slightly finer toward apex. 



Hemelytron : Clavus and corium polished ; clavus with one complete 

 and basal half of second row of punctures; corium with numerous 

 punctures becoming larger and more crowded basally ; costa with two 

 to four setigerous punctures; membranal suture vu-tually straight, 

 lateral angle not produced; membrane surpassing apex of abdomen. 



Propleuron: Shining, with few punctures in depression; prosternal 

 carinae about half as high as labial II. 



Mesopleuron : Evaporatorium following posterior margin to lateral
