190 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



Scudder has properlj' synonyniized Eedtenbacher's curtipenne 

 with the present species. ^^ 



The present insect is veiy striking in form, coloration and 

 ovipositor, which latter, though not strongly, is more decid- 

 edly curved than in any other North American species of the 

 genus. The species is dark brown in general coloration, often 

 stronglj^ tinged with burnt lake and sometimes with green; the 

 dorsum of the pronotum, particularly in paler individuals, is 

 bordered bj^ very narrow lateral lines of the same pale color which 

 make the tegminal veins and veinlets so conspicuous in the pres- 

 ent species, these lateral hues are continued on the head, con- 

 verging to the vertex which they border. 



Lateral lobes of pronotum with cephalic margin moderatel}^ 

 convex to the ventro-caudal angle with the ventro-cephalic angle 

 weakly indicated, ventro-caudal angle rather broadly rounded, 

 rectangulate, caudal margin exceedingly weakly convex to the 

 subobsolete humeral sinus, convex callosity moderately broad. 



Macropterism is very rare, we have but two examples of this 

 condition before us, females from Plummer's Island, Maryland, 

 and Asheville, North Carolina. 



The genicular areas of the caudal femora are alwaj^s iiifuscated; 

 the genicular lobes of the same are each furnished with a single 

 rather heavy spine or very occasional^ bispinose; the ventral 

 margins of the caudal femora are unarmed. 



The ovipositor length is as follows: Beatt^-, Pennsylvania, 

 9.2; Asheville, North Carolina, 8.6-9.5; Marion County, Indiana, 

 8.8-9; Mohne, IlHnois, 8.6; West Point, Nebraska,^" 7.8-8.7 

 mm. Though normally distinctly but not very strongly curved, 

 the ovipositor is found to vary occasionally in the degree of this 

 curvature as well as in length and heaviness. 



The present species is widely distributed over the upper Miss- 

 issippi valley region as far north as West Spring Green, Wiscon- 

 sin, and is known eastward as far as the Hudson Palisades in 

 New Jerscj^; Harrisburg, Pennsylvania; Washington, D. C, and 

 Asheville, North Carolina, and westward as far as West Point 

 and Lincoln, Nebraska, and Wichita, Kansas.

*" One female from West Point, Nel)raska, lias the ovipositor only 6.7 mm. 

 in length, but the whole organ appears to be somewhat abnormal and we have 

 consequently omitted reference to this individual elsewhere.
