\ The largest of our species of Melanopli and heavy bodied; excepting 

 the hind legs and the lateral lobes of the proiiotum, the general color 

 is a nearly uniform brownish testaceous, becoming paler testaceous in 

 specimens from arid regions; in those from Nebraska, Kansas, and 

 Colorado it is sometimes a blackish green, while in those from Illinois 

 and Indiana it is often of a dark brownish green. The head has some- 

 times a pair of dusky, divergent stripes, passing from the posterior 

 corners of the fastigium backward across the vertex and, when these 

 are present, there are often other but irregular streaks of similar tint 

 on the genae and clouds over parts of the face; the vertex is gently 

 arched, more gently in the female than in the male, with a broad inter- 

 val between the eyes, the fastigium broadly and not very deeply 

 impressed; frontal costa broad but narrower than the interspace 

 between the eyes, percurrent, equal except for a slight expansion below, 

 broadly and shallowly sulcate below (and including) the ocellus, punc- 

 tate; eyes moderately prominent, short, not a great deal longer than 

 broad; antennae fulvo-testaceous, nearly twice as long (male) or fully
