ORTHOPTERA. 149 



13. Locusta (Chlocaltis) conspersa. Sprinkled locust. 



Light bay, 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 y\ inch. 



This may be merely a variety of the following species, though 

 very differently colored. 



14. Locusta (Chlo'ealtis) 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 hues 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 j\ 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. Leonard informs me 

 that they are found paired. I have captured the abortive locust 

 in pastures near the end of July. 



15. Locusta (Chlo'ealtis) 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-covers, in the male, 

 as long as the abdomen, in the female, covering two thirds of the 

 abdomen ; wings rather shorter than the wing-covers, transparent, 

 and faintly tinged with yellow ; hinder knees black ; spines on 

 the hind shanks tipped with black. Length from | to more than 

 j\ inch ; exp. from -^^ to nearly 1 inch. 



The flight of the short-winged locust is noiseless and short, 



* This species closely resembles a Swedish insect which I have received under 

 the name of jiarallelus, ZetterstedL ; but is evidently distinct from it.
