MORSE: ORTTIOPTERA OF NEW ENGLAND. 457 
proportions are doubtless greater than exist in the field, since 
the collector naturally retains more of the rarer form. The 
proportion appears to vary geographically, since in some districts 
green males are almost unknown. 
This, the most abundant of our springtime Locusts, is rather 
generally distributed but is found most plentifully in old, grassy 
mowing-fields and pastures, in l)Oth the drier and the moister 
portions, and though not partial to actually wet soils, seems to be 
equally at home in either. 
It takes wing readily, but its flight is short, seldom over a rod 
or two in length. The niale often flies in a circling course, and 
frequently stridulates, producing a fine, sharp crepitation; the 
female flies farther and in a more direct hne. 
The season during which adults may be found is the longest for 
any New England species of the group. They begin to appear in 
April, usually in the third week in the vicinity of Boston, are 
abundant in May and June, common in July, scarce in August, 
and occur rarely in September, October, and November. Owing 
to this fact, the species has been reported as double-brooded, but 
this is quite improbable in New England. Three females, taken 
in Massachusetts on November 8 and 17, had wings in unworn 
condition and had probably gained them that season through 
accelerated development. 
The young may be readily found in the latter part of August 
and during the remainder of the season in the haunts of the adult. 
On mild sunny days in winter when the ground is bare they may be 
met with along the edges of woodlands on southward-facing slopes 
and in sheltered nooks. Here, in company with the young of the 
Coral-winged and Spring Yellow-winged Locusts they may be 
found hopping actively about on the approach of the stroller, pat- 
tering like hailstones on the dry leaves under foot. I have found 
them thus in midwinter within a yard of a long drift of unmelted 
snow. 
This Locust doubtless inhabits the whole of New England. It 
has been recorded from every State and some of the off-shore 
islands. It is also widely distributed over the continent as a 
whole.
