Pronotiim: Length more than half width, 1.90(1.75-2.02) :3. 35 

 (3.06-3.55); anterior margin shallowly, doubly emarginate; lateral 

 margins straight to very slightly sinuate opposite ends of transverse 

 impression, with six setigerous submarginal punctures; transverse 

 impression weak, obsolete at middle, marked by medially interrupted, 

 irregular row of coarse punctures; surface elsewhere impunctate 

 except for prominent punctures laterally on anterior lobe and a few 

 medially on posterior lobe. 



Scutellum; Length equal to, longer, or shorter than width, 2.10 

 (1.92-2.22) :2.09(1.89-2.28); surface polished, basal third to fourth 

 impunctate, disc with several widely scattered, coarse punctures and 

 numerous interspersed minute punctures, latter extending to apex. 



Hemelytron: Clavus and corium shining, very weakly alutaceous; 

 clavus with a partial row of punctures; mesocorium with two complete 

 rows paralleling claval suture, discally with numerous scattered small 

 punctures becoming more abundant and stronger apically; exocorium 

 with few weak punctures scattered over most of its length ; costa with 

 two or three setigerous punctures; membranal suture slightly bisinuate, 

 lateral angle vaguely produced; membrane longer than basal width, 

 distinctly surpassing apex of abdomen. 



Propleuron: Vaguely alutaceous, with no distinct punctures; pro- 

 sternal carinae less than half as high as labial II, sharp. 



Mesopleuron : Lateral area finely alutaceous, impunctate. 



Metapleuron: Evaporatorium moderately concave laterally; lateral 

 area weakly alutaceous, impunctate. 



Legs: Posterior femora not tuberculate veutrally; posterior tibiae 

 not angulate ventrally near base. 



Sternites: Shining, vaguely alutaceous, impunctate but with fine 

 longitudinal rugae in spiracular area. 



Terminalia: Genital capsule rugopunctate laterally, finely punc- 

 tured elsewhere, apical margin weakly sinuate medially; gonostylus 

 as illustrated (fig. 221). 



Length of body: 6.11(5.60-6.71). 



Female : Very similar to male. 



Head: Length-width ratio, 1.23(1.10-1.36): 1.69(1.56-1.84); inter- 

 ocular width, 1.05(0.96-1.16). Antennals: I, 0.30(0.27-0.33); 11, 

 0.30(0.28-0.33); III, 0.41(0.36-0.46); IV, 0.44(0.40-0.50); V, 0.46 

 (0.43-0.50). Labials: I, 0.53(0.50-0.60); II, 0.95(0.86-1.03); III, 0.79 

 (0.63-1.16); IV, 0.56(0.49-0.73). 



Pronotum: Length-width ratio, 2.07(1.89-2.34) :3.61 (3.16-4.11). 



Scutellum: Length-width ratio, 2.19(1.82-2.60) 12.25(1.95-2.53). 



Length of body: 6.53(5.93-7.22). 



Type data.— Signoret misapplied the name rugifrons of Herrick- 

 Schaeffer (now shown to be a synon3rm of Pangaeus hilineatus (Say))
