downward, rounded transversely; the caringe generally slight and o1)(hsc, bnt 

 sometimes slightly prominent; frontal costa slightly prominent between the 

 antennae, but not prominent below, gradually expanding below, more or less sul- 

 cate ; lateral carinae more or less distinct, nearly straight, reaching the corners 

 of the face. Antennse about as long as the head and pronotum, enlarged and 

 flattened at the base, acuminate at the apex, triquetrous. Eyes oblong ovate, 

 oblique, and placed w^ell forward near the antennse. Pi'onotum a little longer 

 than the head, truncate in front; hind border very obtusely angled; sides flat, 

 perpendicular, straight and very near or quite parallel; tricarinate, the three car- 

 inse about equal, distinct, but not pi-ominent, straight, paj-allel ; posterior trans- 

 verse incision situated a little behind the middle, bends forward in the middle, 

 and cuts the median carina; the two anterior incisions sub-obsolete; the poste- 

 rior margin of the side somewhat regularly though slightly curved inward, tlie 

 lower posterior angle being sub-acute. Elytra and wings pass the posterior 

 femora, and are about as long as the abdomen ; the former are narrow and 

 obliquely truncate at the apex. Abdomen sub-cylindrical, elongate, slightly 

 enlarged at the apex ; the upper valves of the ovipositor unusually long and 

 exserted. Posterior femora shorter than the abdomen, not reaching the ex- 

 tremity of the elytra, slender, being but slightly enlarged at the base. 



Color (after immersion in alcohol). — Some specimens pale greenish-yel- 

 low, evidently green when living ; others with a rufous tinge or shade per- 

 vading the whole surface and almost obliterating the green ; the latter variety 

 is generally a little smaller and the head and vertex slightly more ascending 

 than in the other variety. The lateral carinse of the pronotum and a narrow 

 stripe immediately below them brown. Antennse, anterior legs (sometimes 

 the middle ones also), the inside and upper portion of the posterior femora, 

 and posterior tibiae rufous. The face, sides of the thorax, and posterior legs 

 are all bright rufous. Elytra semi-transparent, with fuscous dots along the 

 disk, forming a single row along the basal third, but scattered over the apical 

 portion. Wings pellucid, tinged with yellowish at the base; nerves of the 

 anterior portion roseate in the green variety, somewhat dusky in red variety. 



Dimensions. — Length, l.T.'i inches; elytra, 1.25 inches; hind femora, 

 0.75 inch ; hind tibiae 0.7 inch. East Tennessee (Thomas). 



Remark. — This appears to be a distinct species, although it approaches 

 some of the descriptions of P. hrevicornis, especially the Tr. mridulus, Pal.
