Orthotyhis viridicatiis Uhler n. sp. 



"Oblong-ovate, grass green, opaque, minutely pubescent, pale green beneath. Hear! slightly 

 convex, irapuuctate, broad between the eyes, the vertex transversely sulcate before the carina; 

 the eyes brownish, moderately prominent, well rounded, placed nearly vertical; front convex, 

 contracting below, the tylus narrow, prominent, separated above by a deep groove ; rostrum 

 stout, reaching to the middle coxae, pale green at base, black on apical third ; antennae stout, 

 the basal joint pale green, the second dusky, about equal to the clavus in length, the third and 

 fourth joints dusky, more slender than the second, filiform, and together not as long as that 

 joint. Pronotum wider than long, almost flat, with the lateral margins oblique, and tho 

 anterior angles a very little rounded, the callosities large and tumid, separated by a deep 

 depression, the collam narrow, and confined to a narrow space of the anterior margin, the 

 transverse impressed line behind the callosities slender, but distinct on the outer margin, 

 behind it the margin of the posterior lobe is distinctly reflexed, tlie margin before this callous; 

 posterior margin nearly straight, with the humeral angles oblique and a little curved ; the 

 pleural flap is deep and nearly triangular. Scutellum little longer than wide, feebly convex, 

 faintly carinate at tip. Clavus faintly scabrous, with a few obsolete punctures next the coarse 

 vein, corium minutely and obsoletely scabrous, the cuneus pale yellowish, smooth ; membrane 

 black, with the veins pale yellowish. Abdomen short, minutely pubescent. 



Length to end of abdomen 3 mm. To tip of membrane 4 mm. Width of pronotum 1.85 mm. 

 A few specimens of both sexes have been sent to me for examination. They have been mostly 

 shriveled from immaturity at time of collecting. Three specimens are in the collection from 

 Colorado. Others were obtained in the vicinity of Denver, and in New Mexico. The pale color 

 of head, thorax, sides of corium and cuneus, is owing to fading of color after death of the 

 insect."
