FAMILY VI.— LOCUSTID/E. 233 



The tribe Xiphidiini contains two genera with numerous 

 species, 

 a. Larger and stouter species. Ovipositor short, falcate. 



Orchelimum. 

 aa. Smaller and slenderer species. Ovipositor straight and 



scarcely curved Xiphidium. 



The insects belonging here are usually called "Meadow 

 Grasshoppers." 



GENUS Orchelimum* Serville (1831). 



Size medium, body short and stout; face oblique; vertex 

 with a blunt tubercle at the apex, and meeting a small and 

 similar projection from beneath; antennas very long, thread- 

 like; first joint very stout and cylindrical; second joint con- 

 siderabU^ smaller; pronotum flat on top, lateral carina well 

 rounded, lobes of sides almost parallel, then forming more 

 or less of a triangle at the bottom. Wing-cases of the male 

 narrow, broad to about the middle, then suddenly but grad- 

 uall}^ narrowing; stridulating organ well developed. In 

 the female the wing-cases are of about equal width ; cerci 

 with a sharp tooth-like hook inside, directed inward ; ovi- 

 positor slightly curved, and terminating in a sharp point; 

 anterior pairs of tibiae with a number of spines. 



Man^^ specimens of Meadow Grasshoppers are found in 

 Minnesota, and three at least are common, or fairly so, viz., 

 vulgare, glaberrimum and nigripes. Our species have an 

 ovipositor with a verj' evident curve, not straight or nearly 

 so, and the face without a median brown stripe, 

 a. Posterior femora unarmed beneath. 



b. Tegmina broader at base; the apical third narrower; 

 body robust, 

 c. Tegmina and wings sub-equal in length ; size 



medium vulgare. 



cc. Tegmina distinctly shorter than wings ; size 

 large glaberrimum.
