The marbled locust, which is one of our prettiest species, 
is found in the open places contiguous to or within pitch-pine 
woods, fly ing over the scanty grass and reindeer moss which 
not unfrequently grow in these situations. It is marked on 
the wings somewhat like the barren-ground locust, but is 
invariably smaller, with the thorax much more contracted 
before the middle. It appears, in the perfect state, from the 
middle of July to the middle of October.
