ORTHOPTERA. 143 



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 transformation in 

 the spring ; but its history is not yet fully known to me, and this 

 opinion is the result only of conjecture. 



3. Locusta sulphurea. Yellow-winged locust. 



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 j% to l^ inch ; exp. 1| to 2^ 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 

 Jicridium sulphureum. It is a rare species in this vicinity. I 

 have taken it, though sparingly, in its perfect state, in May ^nd 

 in September. The elevated ridge on the top of the thorax is 

 higher than in any other species found in Massachusetts. 



4. Locusta maritima. Maritime locust. 



Ash-gray ; face variegated with white ; wing-covers sprinkled 

 with minute brownish spots, and semitransparent at tip ; wings 

 transparent, faintly tinted with yellow next the body, uncolored at 

 tip, with a series of irregular blackish spots forming a curved 

 band across , the middle ; hindmost shanks and feet pale yellow,
