distinctly reflexed, submargin with distinct pegs and a few long cilia, 

 surface shining and with short radiating rugae and punctures; vertex 

 with few or no punctures; jugum ventrally and maxillary plate (ex- 

 cept posteriorly) impunctate. Antennal segments: I, 0.28(0.26-0.30); 

 II, 0.28(0.26-0.30); III, 0.31(0.30-0.33); IV, 0.30(0.30-??); V, 

 0.33(0.33-??). Bucculae shghtly lower than height of labial II, eva- 

 nescent posteriorly; labium reaching between middle coxae. Labial 

 segments: I, 0.58(0.56-0.00); II, 0.69(0.63-0.76); III, 0.51(0.43-0.60); 

 IV, 0.36(0.34-0.38). 



Pronotum: Width shghtly more than twice length, 2.92(2.79- 

 3.06): 1.39(1.36-1.43); anterior margin moderately deeply and almost 

 simply emarginate; side margins subparallel on basal fourth, thence 

 gently narrowed to broadly rounded anterior angles, not emarginate 

 opposite ends of transverse groove; lateral submarginal row of some 

 30 setigerous punctures giving rise to long, reddish cilia; transverse 

 groove broad, very shallow, situated near basal fourth; anterior lobe 

 with broad lateral area and narrower anterior area with distinct 

 punctures, calli and median line impunctate; posterior lobe and trans- 

 verse groove with numerous scattered, distinct punctures across width. 



Scutellum: Distinctly longer than wide, 2.15(2.02-2.28) : 1.85(1.75- 

 1.95); triangular, apex narrowed, disc with numerous distinct punc- 

 tures which are missing from narrow basal area and are more numer- 

 ous at apex. 



Hemelytron: Corial areas weakly defined; corium and clavus with 

 numerous distinct punctures, these more dense on exocorium and in 

 single impressed row paralleling claval suture; membranal suture 

 bisinuate and slightly acute laterally; membrane somewhat longer 

 than wide, just attaining apex of abdomen. 



Propleuron: Polished, impunctate, prosternal carinae low, rather 

 sharp. Mesopleuron: Evaporatorium extending uninterrupted into 

 posterolateral angle of segment. Metapleuron: Evaporatorium oc- 

 cupying mesal two-thirds of segment, lateral margin concave; lateral 

 area impunctate; peritreme reaching almost to middle of segment, 

 apex fused with cuticle. 



Venter: Shining, impunctate, with a few weak, usually short rugae 

 laterally. 



Terminalia: Subgenital plate not reflexed marginally, apex feebly 

 convex with the faintest trace of a median emargination; gonostyli 

 as illustrated (fig. 249). 



Length of body: 5.55(5.24-5.87). 



Female: Generally similar to male. 



Head: Length-width ratio, 0.98:1.40; interocular width, 0.96. An- 

 tennal segments: I, 0.30; II, 0.33; III, 0.30; IV, 0.36; V, ??. Labial 

 segments: I, 0.55; II, 0.70; III, 0.50; IV, 0.36.
