18 ENTOMOLOGICAL NEWS. [Jan., ’08 
roads and bare fields from June (Dissosteira) or July (Trim- 
erotropis) to early December. The latter species seems to 
be seldom found away from roads except in the latter part of 
its seasonal range, and is furthermore the only Acridiid which 
I have noted as being attracted to lights. 
Subfamily AcRIDIINAE 
Leptysma marginicollis apparently overwinters as adult, and 
is confined to marshes except in late fall when I have col- 
lected it on dry ground among broom straw (Andropogon). 
Apparently ranges through nearly the whole year. 
Of the three Schistocerce found here, alutacea occurs 
chiefly on the uplands from early August to early October, 
not overwintering in the adult stage like the other two species, 
e 
while damnifica has been taken from mid-September to late | 
April, its habits in winter being similar to those of americana. 
S. americana, our third species, occurs throughout the entire 
year, the nymphs which are dimorphic in color, some being 
brown and others green, transform to the adults from the end 
of August to the middle of October. The adults leave the 
fields and take to the woods during the winter and are liable to 
be on the wing on any comparatively warm day. In spring 
they leave the woods and take to the fields again, being found 
in May and June on crimson clover and grain; about this 
time the sexes are found in coitu. In July and August their 
numbers rapidly diminish, but old adults were brought me in 
September, 1907, at the same time as newly transformed speci- 
~ mens. 
Of our Melanopfli, atlanis occurs in grassy fields from June 
to December, an occasional specimen lingering on till January; 
while femur-rubrum only occurs from September to late Noy- 
ember though very abundant in grassy fields at that season. 
The other two common species, keeleri and scudderi, occur in 
or near pine woods mostly, their range being from mid-August 
to early December, though I took specimens of the latter on 
January 21 and 22, 1906. Our only other form punctulatus, 
occurs in pine woods, but we have only taken four specimens 
(on October 9 and 19, and November 5, 1907).
