ORTIIOPTERA. 155 



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 v^^hich grows near the edges of our sandy 

 beaches, 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 lo- 

 cust, informed me that it was his Gri/Ilus eqimlis, probably 

 intended for oequalis. It is found, daring the months of July 

 and August, on dry barren hills and on sandy plains, upon the 

 scanty herbage intermingled with the reindeer moss. 



6. Locusta latipennis. Broad-winged locust. 



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

 semitransparent 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 -^^ inch; exp. 

 l^Q inch.
