turn with discoidal margins pale, calli and posteriorly on disk 

 black, forming a ray behind each callus and thus leaving the 



median line pale alnicola 



Second antennal segment without prominent exserted hairs, or if 

 present, not equal to more than twice the thickness of the seg- 

 ment; pronotal disk without distinct rays, sometimes black but 

 the lateral margins not distinctly paler aphidiphagus 



7. (i) Hind femora with two brown or fuscous bands near the apex; 



apical half of membrane with a distinctly rounded fuscous spot, 

 usually connected at base by a fuscous streak which extends up 



between the large areoles 8 



Hind femora with but one fuscous band; apical half of membrane 

 pale or clouded with fuscous but the fuscous area not forming 

 a rounded spot on the apical half 9 



8. Calli solid black, a broad piceous ray behind each, in pale specimens 



the calli may be somewhat brownish but in such case the median 

 line and margins of disk are distinctly pale, leaving a dark brown 

 ray behind each callus, hemelytra with piceous on clavus and 



corium, embolium pale borealis 



Calli more or less invaded with brownish or pale, distinct rays not 

 apparent behind calli ; hemelytra and pronotum more uniformly 

 colored, f ulvo-testaceous to dark brownish f asciolus var. castas 



9. Dorsum uniformly brownish black; calli and scutellum blackish 



similar to the whole dorsum davisi 



Dorsum pale to testaceous and brownish, frequently becoming 

 fuscous or blackish but always with some pale; calli margined 

 with black or entirely black 10 



10, Calli black only around the margin, dorsum rich brownish to fusco- 



brownish, shining , nitenatus 



Calli entirely black, or if not, then the dorsum pallid testaceous 

 and with three pustulate fuscous spots, one at apex, middle, and 

 base of each hemelytron 11 



11. Dorsum fuscous to blackish, usually with a pale median line running 



over the disk and scutellum, hemelytra darkened to such an extent 



that three pustulate fuscous spots are not apparent quercicola 



Dorsum pallid testaceous with three pustulate fuscous spots, one 

 at base, middle, and apex of each hemelytron; calli usually black 



but in pale specimens only margined with black . ,

Length 6-7 mm., width 2.85-3 t^^^- I elongate, largely pale and 

 marked with piceous ; calli deep black, a broad piceous ray behind 

 each, thus leaving the median line and margins of the disk pale or 

 testaceous ; embolium pale translucent, membrane with a distinctly 

 rounded fuscous spot on the apical half, usually connected at base 

 by a fuscous streak extending down from between the areoles.
