THE YELLOW-WINGED LOCUST. 177 



isli border not so much narrowed behind. It cannot be 

 mistaken for the fenestralis, which M. Serville describes as 

 having the antennae nearly as long as the body, whereas in 

 this species they are not half that length. The coral-winged 

 locust is the first that makes its appearance with wings in the 

 spring, being found flying about in warm and dry pastures 

 as early as the middle of April or the first of May, and is 

 rendered very conspicuous by its bright-colored wings, and 

 the loud noise which it makes in flying. It probably passes 

 the winter in the pupa state, and undergoes its last transfor- 

 mation in the spring ; but its history is not yet fully known 

 to me, and this opinion is the result only of conjectm'e. 



3. Locusta sidphurea}' Yt'liow-winged Locust. (Plate I. Fig. 6.) 



Dusky brown ; thorax slightly keeled in the middle ; wing- 

 covers ash-colored at their extremities, more or less distinctly 

 spotted with brown ; wings deep yellow next to the body, 

 dusky at tip, the yellow portion bounded beyond the middle 

 by a broad dusky brown band, which curves and is prolonged 

 on the hind margin, but does not reach the angle next to the 

 extremity of the body ; hindmost thighs blackish at the end, 

 and with two black and two whitish bands on the inside ; 

 hindmost shanks and their spines black, with a broad whitish 

 ring just below the knees. Length -f^ to 1-^ inch ; exp. If to 

 25- inches. 



This insect agrees tolerably well with the brief description 

 given by Fabricius of his Gryllus sulphureus, except that the 

 wings are not sulphur-yellow, but of a deeper tint. It is also 

 described and figured by Palisot de Beauvois under the name 

 of Acridium suJplaireimi. It is a rare species in this vicinity. 

 I have taken it, though sparingly, in its perfect state, in ]\Iay 

 and in September. The elevated ridge on the top of the 

 thorax is higher than in any other species found in Massachu- 

 setts.
