behind. The 'wing-covers and wings are extremely short. 

 The hind legs are long and slender. I propose therefore to 

 separate these species from the other locusts under a sub- 

 genus by the name of Ohloealtis, derived from the Greek, 

 and signifying a grasshopper. 



13. Locusta {Ohloealtis) conspersa. Sprinkled Locust. 



Light hay, sprinkled with black spots ; a black line on the 

 head behind each eye, extending on each side of the thorax 

 on the lateral elevated line; wing-covers oblong-oval, pale 

 yellowish brown, with numerous small darker brown spots ; 

 wings about three twentieths of an inch long, transparent, 

 with dusky lines at the tip ; hind shanks pale red, with the 

 spines black at the end. Length nearly -j^ inch. 



This may be merely a variety of the following species, 

 though very differently colored. 



14. Locusta (Ohloealtis) abortiva. Abortive Locust. 



Brown ; wing-covers with dark brown veins and confluent 

 spots, covering two thirds of the abdomen ; wings three 

 twentieths of an inch long, transparent, with dusky lines at 

 the tip ; hind margin of the thorax straight ; hind shanks 

 coral-red, whitish just below the knees, the spines tipped 

 with black. Length nearly T 9 ^ inch. 



This and the preceding locust have much the appearance 

 of pupae or young insects ; nevertheless I believe that their 

 wings and wing-covers never become larger, and Mr. Leon- 

 ard informs me that they are found paired. I have captured 

 the abortive locust in pastures near the end of July. 



15. Locusta (Ohloealtis) curtipennis. Short-winged Locust.

Olive-gray above, variegated with dark gray and black; 

 legs and body beneath yellow ; a broad black line extends 

 from behind each eye on the sides of the thorax ; wing-cov-
