General color black, shining; elytra pale straw-yellow with a com- 

 mon broad postmedian blackish bar; legs and joints 1 and 2 of antennae 

 reddish-yellow, remainder of antenna? and tips of tarsi fuscous. Joint 

 1 of antennae stout, feebly curved, slightly longer than head; 2 — 4 much 

 more slender, 3 one-fourth shorter than 2, one-half longer than 4. Thorax 

 subcylindrical, its subapical constriction deeper than the one at basal 

 third, the space between them smooth, convex, the apical and basal areas 

 finely rugose. Elytra, brachypterous form, reaching sixth dorsal, their 

 tips broadly separately rounded. Length, 4 — 4.5 mm. 



Argo, 111., July 31 — Aug. 7 (Gerhard). Ranges from On- 

 tatrio and northern New York west to Wisconsin and Utah.

X. Pithanus Fieber, 1858, 303. 



Elongate, opaque, glabrous species having the head trian- 

 gular, almost vertical, rather wide, apex not compressed ; eyes 

 subspherical, rather prominent, contiguous to pronotum ; an- 

 tennae finely pubescent, joint 1 short, stout, curved, not reach- 

 ing tip of tylus ; beak reaching hind coxae ; pronotum feebly 

 constricted near apex, its median area strongly swollen to form 

 two prominent calli, the area behind these very short, finely 

 transversely rugose, the hind margin subtruncate ; scutellum 

 convex, wholly visible, minutely strigose ; elytra dimorphic, 

 in macropterous forms surpassing abdomen, cuneus ill-defined, 

 membrane with but one distinct cell; in brachypterous form 

 strongly abbreviated, subequal in length to pro- and mesonota 

 united ; abdomen elongate or elongate-oval, base not constrict- 

 ed, margins strongly reflexed ; first joint of hind tarsi twice 

 the length of second. One species occurs in the eastern states. 



659 (918). Pithanus m^erkelii (Herrich-Schaeffer), 1839, 78. 



Brachypterous Female — Subcylindrical, rather robust. Black, sub-

 verse spots on vertex, entire corium, reflexed margin of dorsum, beak 

 except tip and middle of ventrals 1 — 3, yellowish-white; legs reddish- 

 yellow, a row of dots on under side of hind femora, tarsi in part and 

 antennae, except basal joint, fuscous. Joint 2 of antennae about four times 

 the length of 1, 3 and 4 filiform, united slightly longer than 2, 3 twice 

 as long as 4. Elytra very short, barely covering first dorsal, their tips 

 truncate. Clavus scarcely distinct from corium, finely transversely ru-
