Diagnosis.— The small size of the apical lobe of the peritreme sepa- 

 rates this species from the other member of the genus. 



Description. — Male: Broadly to very broadly oval. 



Head: Length about two-thirds width, 0.82(0.80-0.83) : 1.14(1. 13- 

 1.16); interocular width, 0.85(0.83-0.90); anterior outline a strongly 

 flattened semicircle, juga slightly longer than clypeus; surface shinmg, 

 feebly rugae, with small punctures, somewhat tumid just mesad or 

 submarginal row of punctures; juga ventrally and maxillary plate 

 impunctate. Antennal segments: I, 0.26(0.24-0.28); II, 0.14(0.13- 

 0.16); III, 0.19(0.19-0.20); IV, 0.20(0.20-0.20); V, 0.20(0.20-0.20). 

 Bucculae slightly lower than labial II, evanescent posteriorly; labium 

 reaching between middle coxae. Labial segments: I, 0.41(0.40-0.43) ; 

 II, 0.52(0.48-0.56); III, 0.41(0.40-0.44); IV, 0.28(0.26-0.30). 



Pronotum: Length less than half of width, 1.15(1.14-1.17) :2.47 

 (2.40-2.55); anterior margin deeply and smgly emargmate; lateral 

 margins entire, not emarginate, submarginal setigerous punctures 

 very numerous, arranged in a narrow stripe (not in a single row) ; 

 transverse groove behind middle, absent medially and faintly indi- 

 cated laterally; anterior lobe distinctly punctured only subapically 

 and laterally; posterior lobe punctured, finely so on disc and more 

 coarsely so laterally. 



Scutellum: Wrinkled, punctures absent at base and becoming pro- 

 gressively coarser and much more numerous to apex. 



Hemelytron: Corium distinctly convex, areas well defined; disc 

 with a single, sunken row of close-set punctures paralleling claval 

 suture, elsewhere sparsely punctured; exocorium more densely punc- 

 tured; costa with 25 or more setigerous punctures; clavus with two 

 longitudinal rows of punctures; membranal suture almost straight, 

 rectangular at outer angle; membrane usually short, about as long as 

 basal width. 



Propleuron: Impunctate; prosternal carinae very low, thick, 

 evanescent ventrally. 



Mesopleuron : Lateral area sparsely rugopunctate.
