BraohyjRerous form (fig. .58(1.2). Pronotum nmoh reducf'd, about half 
a.s long as head, flat; the cariuae obsolescent. Scutellum shorter than head 
(23 to 2.5), the sides slightly and obtusely elevated, the disc concave. Ilemi- 
el,vtra (d' 9) n little longer than scntelhnn; corial veins (jbsolescent ; mem- 
brane absent. 
d (fig- oSb). Fifth ventral segment a little shorter than sixth; genital 
segment rather short, stronglj' convex. Length, 5 mm. 
9 (fig. 5Sa). Posterior margin of dorsal genital segment sinuate, con- 
cavely curved at middle; genital lobes irregularly eroded, the tooth and 
sinus very variable in form. Length, .5. .5 to G..5 mm. 
Tyjie specimens (South Carolina) in the Stockholm IMuseum. 
This widely distributed and locally common species is readily 
recojiuized b}' the structure of the antennae, the straight pro- 
notal margins in the macropterous form, and the genital char- 
acters. Heidemann (1901) was the first to locate it, subseciuently 
to the original discovery, and later (1904) had specimens from 
the National Aluseum collection compared with Stabs types.

Description . — Dark grayish brown; antennae black; apical angles of con- 
nexival segments obscurely pale; ventral surface dark reddish brown. 
Head slightly broader than long (2() to 2.5), longer than ]n-onotum (25 to 
20); tylus short, distinctly narrowed from base to apex; impressions of ver- 
tex broad, moderately deej), divergent, indistinctly connected posteriorly; 
lireocular and jiostocular tubercles obsolete; antenniferous sjnnes extremely 
short, acute, scarcely divergent, the lateral tooth obsolescent; antennae 
(fig. 59c) cylindrical, moderately stout, about as long as head and jn'onotum 
together, the first segment elongate, reaching anterior fourth of tylus, length 
of second somewhat less than distance between eyes (15 to IS); rostrum 
extending a little beyond level of posterior margin of eyes. Pronotum (fig. 
59(1) moderately convex, lateral margins slightly curved, a little expanded 
and reflexed, granulate; cariuae indistinct, the median pair conjointly ele- 
vated and obsolescent in posterior fourth, intermediate i^air scarcely devel- 
oped, lateral pair distinct. Scutellum much longer than head (84 to 25), 
shaped as in niger (fig. .5Sd.l); .sides distinctly elevated; discal elevation 
low, rounded. Hemielytra ( 9 ) moderately narrowed, exposing most of 
connexivum at sides, not reaching dorsal genital segment, corium to middle 
of third segment; exocorium moderately and unevenly exi)an(led at base; 
mesocorium with one, endocorium without distinct transverse veins; veins 
of membrane reticidate toward aj^ex. 
Unknown. 
9 (fig. 59a). Posterior margin of dor.sal genital segment slightly sinuate, 
almost straight at middle; abdomen rather broadlj’ oval, one-half wider 
than pronotum (75 to 50). Length, 7. 6 mm.
