THE YELLOW-WINGED LOCUST.

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 conjecture. 
3. Locusta sulphured. 12 Yellow-winged Locust. (Plate I. Fig. G.) 
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 -&■ to If inch ; exp. If to 
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 sulpliureum. It is a rare species in this vicinity. 
I have taken it, though sparingly, in its perfect state, in May 
and in September. The elevated ridge on the top of the 
thorax is higher than in any other species found in Massachu- 
setts.
