Iluacora viridis Uliler n. sp. 



• "Bright grass green, narrow, not highly polit-hecl. Head flat as usual, set with black 

 stiff pubescence, with the vertex more or less broadly impressed before the sharp occipi- 

 tal carina; front 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 tliird. Pronotum trapeziform, 

 almost flat, very gently sloping, set with erect blackish pubescence anteriorly 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 obliciue, refiexed 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; membrane 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 

 1.33 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 the 

 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."

Length to tip of abdomen a.75-3 mm. To tip of membrane 3-3.25 mm. Width of 

 pronotum 1.25 mm. One specimen from Colorado h^prings. taken in August by Mr. E. S. 

 Tucker, is darker and less rufous than the others that 1 liave examined; it has also more 

 white at the base of membrane. Other specimens have been collected in Illinois by Mr. 

 Bolter and Mr. Stromterg; at Lancaster. N. Y. in August by Mr. VanDuzee: in C:.i,a by 

 Dr. Gundlach, in .San Domingo by myself, as also in Texas and Florida. A ft.; m appearing
