170 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERa) 



Lateral lobes of pronotum decidedly broad, cephalic margin 

 moderately oblique and nearly straight to the broadly obtuse-an- 

 gulate ventro-cephalic angle, thence nearly straight and decidedly 

 more horizontal than is usual to the rather sharply rounded ven- 

 tro-caudal angle which is rectangulate, caudal margin weakly sin- 

 uate but nearly straight, humeral sinus obsolete, convex callosity 

 very broad. Tegmina broadly rounded at apex. Genicular 

 lobes of caudal femora normally unispinose, sometimes supplied 

 with a small supplementary spine; genicular areas of same dark- 

 ened; ventral margins of caudal femora unarmed. 



In addition to the type series (the type and allotype in the 

 United States National Museum and a paratypic pair in the 

 Hebard Collection), we have examined but two unrecorded speci- 

 mens. The species is further known only from specimens taken 

 by Allard at Indian Grave Gap, Towns County, Georgia.

 1841. Orchelimum gracile Harris, Ins. Inj. Veget., p. 131. [Ma.ssachusetts.] 



Harris' description of his gracile, giving a nearly straight ovi- 

 positor and other characters, shows unquestionably the present 

 synonymy; the figure of a female accompanying the same 

 description in the Flint edition ^* belongs, however, to an Orcheli- 

 vium, probably concinnum Scudder, the curved ovipositor show- 

 ing at once that the specimen selected for the figure by Dr. 

 Agassiz was not the species described by Harris. 



The present species is not, as has been generally supposed, 

 found far south of the borders of the United States, and the only 

 exotic material of the species now before us is from Bermuda.
