144 INSECTS INJURIOUS TO VEGETATION. 



with the extreme points of the spines black. Length | to l^ 

 inch ; exp. ly\ inch to 2| inches. 



This species comes very near to Mr. Kirby's description of 

 the Locusta leucostoma ; but is evidently distinct from it, and 

 does not appear to have been described before. I have received 

 it from Sandwich, and have found it in great abundance among 

 the coarse grass which grows near the edges of our sandy beach- 

 es, but have never seen it except in the immediate vicinity of the 

 sea. It comes to maturity and lays its eggs about the middle of 

 August or a little later. 



5. Locusta cequalis. Barren-ground locust. 



Ash-gray, mottled with dusky brown and white ; wing-covers 

 semitransparent at tip, with numerous dusky spots which run 

 together so as to form three transverse bands ; wings light yellow 

 on their basal half, transparent with dusky veins and a few spots 

 at the tip, with an intermediate broad black band, which, curving 

 and becoming narrower on the hind margin, is continued to the 

 inner angle of the wing ; hindmost shanks coral-red, with a broad 

 white ring below the knees, and the spines tipped with black. 

 Length 1^ inch ; exp. 2| inches. 



Mr. Say, to whom I sent a specimen of this handsome locust, 

 informed me that it was his Gryllus equalis, probably intended for 

 cequalis. It is found, during the months of July and August, on 

 dry barren hills and on sandy plains, upon the scanty herbage in- 

 termingled with the rein-deer moss. 



6. Locusta latipennis. Broad-winged locust. 



Ash-colored, mottled with black and gray ; wing-covers semi- 

 transparent beyond the middle, with numerous blackish spots which 

 run together at the base, and form a band across the middle ; 

 wings broad, light yellow on the basal half, the remainder dusky 

 but partially transparent, with black network, and deep black at 

 tip, and an intermediate irregular band, formed by a contiguous 

 series of black spots, reaching only to the hind margin, but not 

 continued towards the inner angle ; hindmost shanks pale yellow, 

 with a black ring below the knees, a broader one at the extremity, 

 and a blackish spot behind the upper part of the shank. Length 

 y\ inch ; exp. lyV inch.
