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

remainder dusky but partially transparent, with black net¬

band, formed by a contiguous series of black spots, reaching 
only to the hind margin, but not continued towards the inner

the knees, a broader one at the extremity, and a blackish

wing-covers marbled with large whit¬ 
ish and black spots, and semi-transparent at the end; wings 
light yellow on the half next to the body, transparent near 
the end, with two black spots on the tip, and a broad inter¬ 
mediate black band, which, narrowed and curving inwards

most thighs pale yellow, black at the extremity, and nearly
