KryY TO GENERA OF SALDIN4Z—Concluded: 
EE. At least the inner vein of the corium de- 
stroyed toward apex. First area or interior 
apex of membrane distinctly placed above the 
apex of the second, very rarely almost touch- 
ing this. In this case two veins of corium ob- 
solete. Hemelytra entirely or nearly opaque 
or sericeo-opaque. Micrdacanthia. 
AA. Apex of pronotum always distinctly narrower than the head with 
the eyes. Apical stricture distinct. Callus strongly convex, termi- 
nated by anterior and posterior deep sulci. Marked with punctures 
and little longitudinal wrinkles. 
B. Toward apex of pronotum quite strongly narrowed, sides 
straight, callus by no means touching lateral margins, leaving 
a rather broad margin extended a little behind the middle. 
Hemelytra opaque, only the costal area of corium and em- 
bolium being shiny. Ocelli slightly distant. Toscytus. 
BB. Toward apex of pronotum strongly narrowed, sides more or 
less sinuate. Callus occupying all or nearly all of the width 
of the pronotum, leaving only a narrow or very narrow mar-. 
gin. Ocelli very little separated. Lampracanthia. 
Genus PENTACORA Reuter 1912. 
“Body oblong. Eyes slightly converging anteriorly. Ocelli slightly 
distant or subcontiguous. Tip of rostrum reaching apex of intermediate 
coxe. Second segment of antennez as long as width of head, or distinctly 
longer. Pronotum toward the apex moderately narrow, broadly emargi- 
nate at base. Sides, flattened, lateral margins toward apex strongly 
rounded or forming distinct angles. Callosity by no means touching 
lateral margins, transverse impression placed behind the middle of the 
disk, the scutellum, longer than broad, impressions far remote from base. 
Hemelytra often densely and usually distinctly punctulate. Interior vein 
of corium furcate toward tip, branches touching suture of the membrane. 
Membrane marked by five oblong areas, first or interior area moderately 
produced beyond the base of second. Apex almost attaining apex of 
second. Third segment of posterior tarsi a little shorter than second, 
or subequal to it in length. Last ventral segment of female slightly pro- 
duced, genital segment by no means totally hidden. Type Acanthia 
signoreti Guer. Three Nearctic species, signoreti Guer., ligata, Say, and 
hirta Say.” y

Acanthia signoretii Stal, num. Hemipt., III, 148, No. 1. 
“Oval, sand-yellow with black markings, or black with sand-yellow 
markings, all over minutely sericeous pubescent. Head more or less 
marked with black between the eyes and behind, omitting the amber 
ocelli and two spots on the vertex, or with only two small black spots on 
the vertex; gula with a broad black spot; the emarginated inner side of 
the eyes generally black. Antenne yellow or pale piceous, the basal joint 
black beneath and at base; second joint blackish or dusky beneath; third 
and fourth sometimes blackish beneath, the latter almost as short as the 
basal one, the third longer. Rostrum reaching to behind the middle coxe, 
piceous or black, with the basal joint pale. Face with a longitudiral 
groove, and the cranium with a few wrinkles and ridges. Pronotum' wide, 
deeply concave behind, with the humeral angles drawn out obliquely into
