MORSE: ORTHOPTERA OF NEW ENGLAND. 47.*? 
infuscated posteriorly, with three hirgo pale patches on the 
anterior margin: — 1st, between basal fourtii and half, sejiaratcd 
from 2d by a heavy black patch; 2d, at about three-fifths, also 
succeeded by a black patch (both of these black patches are 
usually narrowed on the front margin of the tegmina). Beyond 
these lies a third smaller pale spot or maculate area which extends 
to the end of the tegraen. Disk of wings yellowish white to 
bright pale yellow, bounded by a broad black band extending 
from near anal angle to costal margin, at its broadest usually equal 
to one-fourth or two-fifths of the length of the wing; beyond this 
the apex more (cf) or less (9) infuscated. Hind femora 
obliquely banded with black. Hind tibiae gray at base, red on 
distal half, clouded at apex and at basal third with fuscous.

The Marbled Locust is one of our handsomest and most 
attractive species, varying astonishingly in color, so much so, 
indeed, that any one accustomed to distinguish 'kinds' or species 
by this character would be led hopelessly astray. 
Its preferred haunts are sandy areas, either bushy or open, and 
it is surprising how effective a protection its tints and markings 
make, notwithstanding their exceptional variety. This protective 
effect is brought about by 'camouflage,' the markings breaking up 
its outline and making it look like nothing in particular on the 
background of sand strewn with withered leaves and other frag- 
ments of vegetable debris. It is, however, conspicuous in flight, 
owing to its rattling crepitation and the contrasting tints of its 
wings. It is wary of approach, yet seldom flies far. Though 
usually numerous in its stations it is of very- local and widely 
discontinuous distribution. Miss Susy C. Fogg has taken it 
at Manchester, N. H., and I have found it not uncommon at 
Provincetown, Dennis, and West Chop, Mass., and North 
Haven, Ct., associated with the Sand, the Seaside, and Boll's 
Locusts. Adults may be looked for from the latter part of July 
till November.
