Hesperotettix pratensis Scudder. 



Head yellowish-green, flecked with fuscous in front, lower portion of 

 face more or less purplish to dark green; a blackish or fuscous stripe on 

 vertex of head usually extending back over the entire pronotum, a lighter- 

 colored median stripe is sometimes present. Pronotum of both male and 

 female increasing slightly from the front backward. All specimens have 

 a pallid line along the position of the lateral carina of the prozona, ex- 

 tending in some cases across the head and following the upper hinder 

 margin of the eye to the vertex, in a few specimens the pallid line also 

 extends backward across the metazona. The white dashes on the lateral 

 aspect of the pronotum usually fade out entirely upon drying. Tegmina 

 rarely as short as the length of the abdomen, in length from 2 to 4 mm. ; 

 the anal vein is usually marked by a distinct pinkish stripe, varying more 

 or less in width. Male cerci straight to feebly downcurved.

JEolo'plus Scudder. 



Body relatively short and stout, considerably enlarged at the meta- 

 thorax, even in the male. Head normal, the eyes moderately distant, not 

 very prominent except sometimes in the male, the summit well arched, 

 the fastigium slightly sulcate between the eyes, the frontal costa mod- 

 erately broad, subequal, plane or nearly plane; antennae moderately stout, 

 cylindrical, equal, slightly longer (male) or slightly shorter (female) 

 than the head and pronotum together. Pronotum stout, regularly in- 

 creasing in size from in front backward, the disk gently convex trans- 

 versely, the prozona slightly and independently tumid, with no or an 

 exceedingly feeble median carina, distinguishing it from the flat 

 carinulate metazona; posterior margin of pronotum very obtusely angu- 

 late, the angle more or less rounded; prozona about half again as long as 

 the metazona, generally slightly broader than long or quadrate. Proster- 

 nal spine conical, erect; interval between mesosternal lobes of male about 

 twice as long as broad, often clepsydral from the convexity of the inner 

 margins of the lobes; of female varying from the same to quadrate; the 

 metasternal lobes attingent or subattingent in the male, a little distant in 

 the female. Fore and middle femora considerably tumid in the male, the
