part of the discoidal area, leaving the triangular field hcliind it 
unspotted and often suffused with brown, rufous, or fuscous. 
Disk of wings very pale whitish yellow, bounded by a nar- 
row fuscous band about one-sixth as wide as the length of the 
wing, widest where it leaves the posterior margin, tapering ante- 
riorly and posteriorly, discontinuous behind the .subniarginal 
offshoot, and fading out posteriorly midway between the widest 
point and anal angle. Beyond this the wing is clear, with some 
of the veins dusky, especially toward the apex. Hind tibiae 
white or j-ellowish white, the spines black-tipped. Hind femora 
with fuscous markings above at approximately two-fifths, three- 
fifths, and apex, the first more or less triangular externally.

This species is easily recognized and is not likely to be mis- 
taken for any other occurring in New England. Its variation 
in color according to the soil of its habitat is striking and is often 
marked even within a small area, as I once noticed at Block 
Island, where the Locusts frequenting a dark portion of the 
beach agreed with it in tint and differed from those from other 
parts of the island. At North Haven, Ct., specimens newly 
captured showed numerous bright rufous flecks, similar to the 
reddish tint of some particles of the soil. 
Drifting gray or yellowish-white sands, dotted with pale-green 
waving tufts and masses of beach-grass (Ammophila arenaria), 
the roar of surf, the salt tang of spray-moistened winds, the 
blinding glare of summer sunshine reflected from sea and sand, — 
these are characteristic elements in the habitat of the Seaside 
or Maritime Locust on the beaches and adjoining dune areas of 
the Atlantic coast from ]\Iaine to North Carolina. I know of 
but one inland locality in New England, at North Haven, Ct., 
w^here it occurs sparingly on sandy wastes now several miles from 
the sea but at one time part of the sea-floor. A variety with 
heavier wing-markings, however, has been described from the 
shores of the Great Lakes.
