Ilnacora viridis Uhler n. sp. 
■‘Bright grass green, narrow, not highly polished. Head flat as usual, set with black 
stiff pubescence, with the vertex mure or less broadly impressed before the sharp occipi¬ 
tal carina; iront prominently convex, wider than long, grooved each side near the eyes; 
tylus short, inferior, placed much below the lower end of the eyes; rostrum dull green, 
broad and compressed at base with the basal joint protracted upon the anterior coxae, 
the tip black, reaching to the middle coxae; antennae dusky greenish, long, growing 
slender towards the tip, the basal joint thick, black at base and apex, much longer than 
the head, the second joint very long, black at base and tip, about equal to the corium in 
length, the third darker, more slender, less than half as long as the second, the fourth 
about equally slender, also dark, much shorter than the third. Pronotum trapeziform, 
almost flat, very gently sloping, set with erect blackish pubescence anteiiorly and on the 
sides; the anterior margin reaching to about the middle of the eyes, with the collum 
raised in the middle; the callosities large, transverse, separated by a deep excavation, 
the anterior angles broadly rounded; the lateral margins oblique, reflexed and sinuated 
posteriorly; the humeral angles a little protracted, forming lobes a little recurved with 
the tip cut obliquely, surface wrinkled, hardly punctate. Scutellum feebly convex, 
acute at tip, sometimes a little whiiish at base. Legs long, the femora green, somewhat 
spotted with white; the tibiae dull yellowish, armed with black spines; tip of tarsi 
piceous. Hemelytra long and ample with the costal border very slightly curved; surface 
of clavus and corium flat, obsoletely scabrous; numbrane smoke brown. Coxae and 
base of venter whitish. 
Length to end of abdomen 4.5 mm. To tip of membrane 5.5 mm. Width of pronotum 
1.38 mm. I have examined four specimens of both sexes, from Colorado. They approach 
I. (Sthenarops) malina Uhler, but differ in the absence of the indented black dots on ihe 
pronotum, and of the black markings of face, in less convex front, and in the color of the 
antennae and scutellum. The form is somewhat variable, as is also the length of the 
hemelytra.”

Sthenarus rubidus Uhler n. sp. 
“Ovate, thick set, dark piceous, polished, covered above with silky yellow, caducous 
scales and fine pubescence. Head broad, feebly convex, a little fulvo-piceous around the 
borders and at base and tip, vertex with a feebly impressed line on the middle, occipital 
posterior ridge distinct; face polished, covered with yellowish prostrate scales; cheeks 
and inner underside of eyes pale yeilowi-h; rostrum piceous, paler rufous at base, reach¬ 
ing to the posterior coxae; antennae, basal joint piceous, thick, scarcely as long as the 
width of the eye, second joint fulvous or piceous, thick, about as long as the pronotum, 
the third and fourth abruptly more slender, pale piceous, together scarcely longer than 
the second. Pronotum convex on the middle and strongly curving down anteriorly, dark 
piceous. or black, polished, covered with yellow scales and fine pubescence, nearly twice 
as wide as long, with the callous humeri subacute, the posterior margin sinuated, with the 
lateral margins curving down; the surface minutely wrinkled, and the pleural flaps trian¬ 
gular, sunken, densely covered with scales and the margins raised in relief. Anterior coxae 
and a spot at tip of mesopleural segment whitish; femora pale rufous, piceous on the 
middle, tibiae paler, the spines black and placed on black dots, tip of the tibiae and of 
the tarsi black. Scutellum unevenly wrinkled, piceous, rufous towards the tip, invested 
with ihe yellow scales. Hemelytra dark brown, fulvous at base, on the suture of clavus 
and on the embolium, apex of Ihe costal border and the cuneus red; surface roughly, 
shallow punctate, covered with jellow scales and finely pubescent; membrane fuliginous, 
white along the border and around the looped vein. Venter fulvous brown, minutely 
pubescent and spiead with bronze-yellow scales. 
Length to tip of abdomen 2.75-3 mm. To tip of membrane 3-3.25 mm. Width of 
pronotum 1.25 mm. One specimen from Colorado Springs, taken in August by Mr. E. S. 
Tucker, is darker and less rufous than the others that I have examined; it has also more 
white at the base of membrane. Other specimens have been collected in Illinois by Mr. 
Bolter and Mr. Stroml erg; at Lancaster, N. Y. in August by Mr. VanDuzee; in Cuba by 
Dr. Gundlach, in San Domingo by myself, as also in Texas and Florida. A form appearing 
be a variety of this species is also found in Mexico.”
