2.73); interocular width, 1.59(1.33-1.70); juga rounded, forming a flat- 

 tened semicircle, almost as long as clypeiis, latter with two subapical 

 setigerous punctures; jugum with a complete, submarginal row of 

 coarse, close-set, setigerous punctures giving rise to long cilia and stout 

 pegs, surface longitudinally depressed either side of clypeus and with 

 scattered minute punctures; ocelli well developed, separated from eye 

 by more than ocellar width; jugum ventrally polished, im punctate; 

 maxillary plate moderately and very closely punctured. Antennal seg- 

 ments: I, 0.55(0.49-0.58); II, 0.68(0.66-0.71); III, 0.59(0.50-0.65); 

 IV, 0.79(0.70-0.86); V, 0.77(0.75-0.81). Bucculae not as high as labial 

 II; labium surpassing middle coxae. Labial segments: I, 1.09(0.91- 

 1.17); II, 1.39(1.20-1.50); III, 1.25(1.03-1.33); IV, 0.89(0.72-1.00). 



Pronotum: Width almost twice length, 5.73(5.03-6.07) :2. 95(2.69- 

 3.26); anterior margin strongly and broadly emarginate; lateral mar- 

 gins entire, with a submarginal row of about 20 setigerous punctures; 

 transverse impression slightly behind midlength, obsolete to absent 

 medially, marked by a single crescentric row of coarse punctures be- 

 hind anterior emargination and a few (one to five) or no punctures 

 laterally; posterior lobe with a few punctures medially and laterally. 



Scutellum: Length equal to or greater than width, 3.78(3.32-4.08): 

 3.69(3.30-3.90); numerous coarse punctures scattered irregularly over 

 surface except across base and apex, latter sometimes with several 

 minute punctures. 



Hemelytron: Corial areas well defined; disc punctured throughout, 

 more obsolctely so medially, two distinct rows of coarse punctures 

 paralleling claval suture; exocorium closely and distinctly punctured 

 for most of its length; costa with six to ten setigerous punctures; 

 clavus with one or two irregular, longitudinal rows of punctures; mem- 

 branal suture broadly, shallowly concave, lateral angle acute; mem- 

 brane usuaU}'^ with distinct fuscous clouds between veins. 



Propleuron: Shining, with a few coarse punctures above acetabulum, 

 in depression and near posterolateral angle; prosternal carinae about 

 half as high as labial II, abruptly terminated posteriorly. 



Mesopleuron: Evaporatorium interrupted on outer half by polished 

 strip along posterior margin of segment; lateral polished area impunc- 

 tate. 



Metapleuron: Evaporatorium occupying more than two-thirds of 

 segment, lateral margin weakly concave; peritreme abruptly termi- 

 nated; lateral area impunctate. 



Sternites: Polished, impunctate, posterior margins sharply and finely 

 crenulate on lateral third or more. 



Legs: Posterior legs distinctly modified, femora convex ventrally 

 with a prominent, subapical, conical tubercle, tibiae abruptly and
