Description.— Male: Oval, widest behind middle. 



Head: Length about two-thirds width, 0.84(0.82-0.90): 1.25(1. 20- 

 1.36); interocular width, 0.85(0.80-0.93); anterior margin a slightly 

 flattened semicircle, clypcus as long as juga; eyes projecting by one- 

 half their length; surface shining, nearly smooth, impunctate. Anten- 

 nal segments: I, 0.24(0.23-0.26); 11,0.22(0.20-0.23); III, 0.27(0.26- 

 0.30); IV, 0.30(0.30-0.33); V, 0.34(0.33-0.36). Bucculae (fig. 33) 

 about half as high as labial II, evanescent posteriorly. Labial 

 segments: I, 0.43(0.40-0.50); II, 0.53(0.50-0.60); III, 0.51(0.46-0.60) 

 IV, 0.33(0.30-0.36). 



Pronotum: Length slightly more than half width, 1.45(1.30- 

 1.69) :2. 76(2.47-3.06); anterior margin shaUowly, doubly emarginate; 

 lateral margin straight in basal two-thirds, submarginally with 18 to 

 20 setigerous punctures; transverse impression somewhat postmedian, 

 weak to obsolete, marked by incomplete row of moderate punctures; 

 anterior lobe polished, impunctate except for few moderate and many 

 minute punctures laterally, subapically with distinctly impressed line 

 terminated laterally at setigerous puncture posterior to inner margin 

 of eye; posterior lobe with few, scattered, moderate to fine punctures 

 discally and laterally. 



Scutellum : Length subequal width, 1 .70 (1 .56-1 .82) : 1 .70 (1 .56-1 .82) ; 

 discally with numerous scattered punctures similar to those of posterior 

 pronotal lobe; apically with punctures finer, more numerous. 



Hem elytron: Clavus and corium shining, very finely alutaceous; 

 clavus with median row of punctures and usually a partial row either 

 side; mesocorium with two complete rows of punctures paralleling 

 claval suture, discally with numerous moderate punctures becoming 

 coarser towards base; exocorium similarly punctate on apical half, 

 costa with five to ten setigerous punctures; membranal suture straight, 

 lateral angle little produced; membrane longer than basal width, 

 surpassing apex of abdomen by about half its length. 



Pleurae (fig. 102) : As described for genus. 



Sternites: Alutaceous, impunctate, slightly rugose laterally.
