 188, 1900, 72. 



A small but comparatively heavy-bodied species, having the cone 

 of the vertex devoid of black markings and without a basal tooth; 

 ovipositor very short and more than usually broad; posterior femora 

 armed beneath on both carinae. Cone of vertex short and stout, the 

 tip round, the deflexcd front with a dull median carina. Pronotum

carinae well defined, the entire surface thickly and rather deeply 

 punctate. Tcgmina long and rather narrow, regularly rounded tci 

 the apex; of a more delicate texture than, in either C. ensiger Harris 

 or C. robusius Scudder. Fore and middle femora with two short 

 spines on the apical third of the lower outer carina. Hind legs short, 

 the tibias but little more than half as long as the closed tegmina; 

 the femora with plainly visible spines on both of the inferior carinae, 

 eight on the outer and six on the inner. Ovipositor a little shorter 

 than the hind tibiae, broadest at a point about two-thirds the distance 

 from the base, thence tapering regularly to a sharp apex. 



General color a very bright grass green. Fastigium tipped with 

 dull yellow, which extends half way down the sides. Labrum and 

 apical segments of all the palpi a rose red tinged with violet. Tarsi 

 somewhat infuscated. Antennae and apical third of ovipositor red- 

 dish-brown. 



Measurements: Female — Length of body, 27 mm.; cone of vertex, 

 2.75 mm.; of pronotum, 7 mm.; of tegmina, 37 mm.; of hind femora, 

 20 mm.; of hind tibiae, 19.5 mm;, of ovipositor, 19 mm. 



This handsome species of C onoceplialus belongs to the same group 

 as C. robustus and C. crepitans Scudder, but is smaller and of a more 

 uniform and brighter green than either of those species, besides hav- 

 ing shorter legs, ovipositor, etc. It is described from a single female
