c. Lateral carina- of pronotum without trace of yellow ; wing cov- 

 ers a bright, grass green, immaculate; ovipositor less than 20 

 mm. in length. 

 13. Conocepiialus palusteis, Blatchley. 



Conocepiialus palustris, Blatchley, Canad. Ent. XXV., 1893, 89. 



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 broad; posterior femora armed beneath on both carin.i . 



Cone of the vertex short and stout, the tip round, the dellexed front 

 with a dull median carina. Pronotum short, broad, the posterior margin 

 regularly rounded, the lateral carina- well defined, the entire surface 

 thickly and rather deeply punctate. Tegmina long and rather narrow, 

 regularly rounded to the apex ; of a more delicate texture than in either 

 C. ensiger, Harris, or C. robustus, Scudder. Fore and middle femora with 

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

 short, the tibia? but little more than half as long as the closed tegmina ; 

 the femora with plainly visible spines on both of the inferior carina, eight 

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

 hind tibia', 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 tin- sides. Labrum and apical seg- 

 ments of all the palpi a rose red tiDged with violet. Tarsi somewhat 

 infuscated. Antenna' and apical third of ovipositor reddish-brown. 



Measurements : Female— Length of body, 27 mm.; of fastigium in front 

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

 20 mm.; of hind tibia', 19.5 mm.; of ovipositor, 19 mm. 



This handsome species of Conocepiialus belongs to the same group as < '. 

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

 and brighter green than either of those species, besides having shorter 

 legs, ovipositor, etc. It is described from a single female taken October 

 21, from the fallen grasses on the margins of a large low-land pond in Vigo 

 county. This pond is surrounded on all sides by heavy timber, and its 

 margins have yielded a number of interesting Orthoptera found nowhere 

 else in the county. Among them are Leptysma marginicollis, Serv., Paroxya 

 atlantica, Scudder, Anaxiphus pulicarius, Sauss., Ph)/Hoscirtes pulchellus, Uhler, 

 and Xiphidium nigropleurum, Bruner. The first four mentioned are insects 

 of a southern range, and perhaps C. palustris will in time be found to be 

 more common southward.
