General aspect very similar to quercicola but differs as follows : more 

 highly polished, calli black around the margins only, dorsum rich brownish 

 to dark brownish and piceous, frequently brownish on scutellum but rarely 

 blackish each side of median line; brachium and apices of the areoles dark 

 fuscous while the apical half of membrane is practically clear; male genital 

 claspers very distinctive. 



$. Length 5.7 mm. Head: width 1.01 mm., vertex .45 mm., length .57 

 mm. ; tylus slightly more prominent but the infuscations are nearly identical 

 with quercicola. Rostrum, length 1.94 mm., nearly attaining posterior mar- 

 gins of middle coxae, pale yellowish, piceous at apex. 



Antennae: segment I, length .48 mm., yellowish, irregularly infuscated on 

 basal half: II, 1.45 mm., yellowish, darkened at apex; III, .68 mm.; IV, .56 

 mm., comparatively longer than in quercicola; last two segments yellowish to 

 fuscous. 



Pronotum: length 1.28 mm., width at base 2.2 mm., anterior angles .88 

 mm., collar .71 mm. ; disk more coarsely punctate on the basal half, dark 

 brownish to piceous. darker on the basal half either side of the median line; 

 calli slightly convex, piceous on the front and hind margins, the disk of each 

 paler and connected at the latero-anterior angles with the pale color just in 

 front; propleura closely punctate, yellowish brown, blackish and opaque sur- 

 rounding the coxal cleft; xyphus pale to brownish. Scutellum strongly con- 

 vex, polished, pale, frequently becoming reddish or brownish each side of the 

 median line, very rarely with blackish. Sternum and pleura brownish black, 

 opaque ; ostiolar pcritreme white. 



Honelxtra : width 2.04 mm., structurally as in quercicola; apical half of 

 corium and invading the cmliolium piceous. the clavus and a spot each side of 

 apex on the corium, basal half of embolium, spot near base of corium, pale to 

 brownish translucent. C uncus pale translucent, punctures black, yellowish 

 brown at apex and becoming fuscous at the inner margin where the brachium 

 joins. Membrane clear or practically so, brachium and apices of the areoles 

 dark fuscous; apical half of membrane distinctly clearer than in quercicola. 



Leys: pale, hind femora with a brownish black mark on the anterior face 

 of apical half, sometimes indicated on the middle pair; tips of tarsi fuscous, 

 claws brownish translucent, arolia typical of the group. 



Venter: brownish to reddish 

 brown and piceous, shining, 

 finely pale yellowish pubescent ; 

 genital claspers (fig. 17) dis-
