"General colour bright grass green (rarely a yellowish brown or tan) 

 with narrow, yellowish lines along the lateral carina? of the pronotum. 

 Posterior tibia? together with all the feet more or less infuscated."— Bru- 

 ner. 



Measurements : Male— Length of body, 28 mm.; of tegmina, 37 mm.; o f 

 pronotum, 8 mm.; of cone of vertex, 3.5 mm.; of posterior femora, 21 mm. 

 Female— Length of body, 33 mm.; of tegmina, 42 mm.; of posterior femora, 

 23 mm.; of ovipositor, 29 mm. 



The above measurements are very nearly the same as those given by 

 Mr. Bruner in the original description of the species, and are the average 

 of a half dozen specimens in my collection. I have one female, however, 

 which is so much larger that at first I was inclined to think it a different 

 species, but the color and structure, except the measurements, agree in 

 every particular with those given above of nebrascensis. The following are 

 the measurements of the specimen in question : 



Length of body, 36 mm.; of cone, 4.5 mm.; of tegmina, 49 mm.; of poste- 

 rior femora, 30 mm.; of ovipositor, 39 mm. 



This species has not before been recorded east of Illinois, but in Central 

 Indiana it is the most common of the three species occurring there. A 

 number of specimens have been taken in Putnam county by Mr. Riley and 

 in Vigo and Fulton counties by myself. When approached it often at- 

 tempts to escape by burrowing beneath the fallen grass. It frequents 

 the same localities as C. ensiger and is very liable to be mistaken for that 

 species by the casual observer, but may at once be distinguished by the 

 characters given above. 



aa. Cone of vertex rather stout, less than 3 mm. in length, devoid of 

 black markings, 

 c. Lateral carina? of pronotum with a yellow line ; wing covers with 

 irregularly distributed black dots ; ovipositor exceeding 2"> 

 mm. in length. 

 12. Coxocepii Airs robustus, Scudder.
