tegmina in length. Yore and middle femora short and stout, un- 

 armed beneath, the former one-third the length of hind femora, the 

 latter a little longer. Hind femora short but slender, armed on both 

 margins of lower carina^ with about nine small but sharp teeth, those 

 on inner carina a little longer and more distant, one from another, 

 than those on outer. Hind tibia^ a little shorter than the femora. 

 Ovipositor slender, of more than average length, of equal width to 

 within 5 mm. of the apex, from whence it tapers gradually to a rather 

 dull point. 



Measurements: Female — Length of body, 44 mm.; of pronotum, 

 9.5 mm.; of tegmina, 50 mm.; of fore femora, 9.5 mm.; of hind 

 femora, 30 mm.; of hind tibiae, 29 mm.; of ovipositor, 45 mm. 



This large and odd ap))earing Tiocustid is represented in my collec- 

 tion by a single female, taken in September, 1900, by Mr. Arthur 

 Dransfield in the campus of the "Working Men's Institute," at New 

 Harmony, Posey County, and kindly presented to me. It is quite 

 distinct from any other species in this country, approaching most 

 closely the Brazilian species C. truncatirostris described by Redten- 

 bacher. The fastigium of the vertex is, however, even longer than 

 in that species. Professor Lawrence Bruner, to w^hom the specimen 

 was sent for examination, writes that he has a single female of the 

 same insect taken from the Potomac bottoms, D. C, some years ago. 

 The male is, as yet, unknown. The species is evidently southern in 

 its range, and should be looked for throughout southern Indiana. 



I take pleasure in naming tliis large Locustid in honor of Prof. 

 Lawrence Bruner, of Lincoln, Nebraska, an authority on North 

 American Orthoptera, who has shown me many courtesies during 

 the preparation of this paper.

General color bright green or pale brown; sometimes a mixture of 

 both; the wing covers usually speckled witli black. Cone of vertex 

 much like that of C. ciisigrr but shorter, with the apex more obtuse; 

 rarely with a black spot at apex, its sides often with a narrow yel- 

 lowish line; the frontal basal tooth distinct but blunt. Posterior 

 femora armed beneath on both carina> with a number of rather weak 

 spines. Wings of mak' equaling tlie tegmina in length, in the fe- 

 male a little shorter. ()vi))ositor shorter than in any of the preced- 

 ing species.
