5. (Female) Hind femora with large irregular pale spots on anterior 



face, spots connected by a longitudinal pale bar although not 



attaining the subapical pale band; large, length 7.3-7.6 mm 



(p. 638) onustus 

 (Female) Hind femora with small spots, without distinct longi- 

 tudinal pale bar on anterior face 6 



6. Membrane with infuscation on central area tending to separate 



into small specks; front of head transversely striate with black 



lines each side of median line (p. 634) neglectus 



Membrane more uniformly infuscated, infuscation not separating 

 into small specks; front of head not distinctly striate with 

 black even when the hemelytra are very dark, although reddish 

 lines usually evident (p. 638) spicatus 



7. (3) Hind femora with distinct white band placed at slightly beyond 



middle of apical half, usually with large pale spots near middle 8 

 Hind femora without distinct white band on apical half, pale spots 

 usually rather small 9 



8. Antennal segment ii distinctly pale or yellowish on dorsal aspect, 



but darker on apex and next to pale annulus at base ; scutellum 

 and clavus clothed with yellowish hairs and intermixed with 

 shorter sericeous white pubescence; membrane somewhat fuscous 



on middle (p. 632) eximius 



Antennal segment ii black except at base, dorsal aspect not dis- 

 tinctly paler; scutellum and clavus clothed with black hairs and 

 intermixed with prominent white sericeous pubescence (p. 640) buenoi 



9. Corium with very heavy triangular black mark set obliquely across 



apex of corium; cuneus usually reddish (p. 640) erectus 



Corium with light, almost interrupted fuscous mark set obliquely 



across apex of corium ; cuneus rarely if ever reddish 



(p. 634) brevifurcatus 



10. ( I ) Corium not distinctly green 11 



Corium distinctly greenish on apical half ; antennal segment ii black 



but with pale annulus at base (p. 640) penipecten 



11. Hemelytra more brownish than black, dark color on apical area 



of corium and on middle of clavus broken into small spots, pubes- 

 cence chiefly golden brown (p. 639) salicis 



Hemelytra sometimes brownish but the dark color not distinctly 

 broken into small spots 12 



12. Front and vertex transversely marked with blackish lines 13 



Front and vertex pale to yellowish, not distinctly marked with 



blackish, rarely with short red lines indicated near each eye; 

 scutellum pale to yellowish, a small rounded brown to fuscous 

 spot each side by margin at middle of apical half (p. 635) angustulus 



13. Scutellum chiefly pale to grayish, but with black mark at each side 



on apical half 14 



Scutellum chiefly brownish black, irregularly maculated with paler, 

 median line slenderly pale but irregularly invaded with darker 

 color (p. 641 ) obtectus 



14. Corium with a longitudinal pale area which extends upon base of 



cuneus without interruption by an oblique infuscation; a black 

 line formed along radius but curving outward apically to the 



fracture (p. 638) lacunosus 



Corium rather distinctly darkened with fuscous on apical half, 

 scarcely showing paler by contrast with dark marks along radius 



(p. 638) cortitectus
