ground in short blue grass and Poa compressa areas in dry fields and 
alovg the edges of woodlands. It was represented by both yellow-winged 
and vermilion-winged individuals, the two forms being present in appar- 
ently equal frequency. 
Spharagmon bolli (Scudder). Frequent in dry open woodland in scrub- 
by and grassy clearings; also along woodland borders, but never in open 
country. 
July 12, a few observed on a hillside covered with open scrub near the 
borders of woods south of West Lafayette (7); July 23, moderately fre- 
quent in an open oak woods south of West Lafayette (17); August 1. 
frequent along the borders of woods on the bluffs at the head of Happy 
Hollow (5) in sparse grass and scrub areas; August 9, a male taken in 
low, humid woods on Burnett Creek (2), probably a stray example from 
the neighboring upland; August 24, several, in open woodland on the 
bluffs at the head of the ravine between West Lafayette and the mouth of 
Indian Creek (8); September 1, several observed in clearings in the 
woods on top the bluffs at the head of Happy Hollow (5); September ¢, 
few seen in a dry grassy area, largely occupied by Andropogon furcatus, on 
a wooded slope (10) hear Wild Cat Creek. 
Dissosteira carolina (Linneus). Common everywhere on bare ground 
and in dry grassy areas, where the grass is short, with patches of bare 
earth intervening. Appeared as adults about July 7 and persisted until the 
end of October. 
Schistocerca americana (Drury). Of sporadic occurrence from late 
March until at least the middle of October, apparently most frequent in 
early fall. 
March (late), a male taken on a building lot at West Fafayette, in 
blue grass (3); July 22, a female taken in a field of soybeans on Purdue 
Experimental Farm (3); September 10, observed a female on Purdue 
Experimental Farm (3) in blue grass; September 30, a male observed on 
Purdue Experimental Farm (3); October 4, a male observed on roadside 
in West Lafayette (8); October 12, a male observed in bunch grass, An- 
dropogon furcatus, on bluff along Wabash bottoms south of Lafayette (13). 
Schistocerca alutacea (Harris). Evidently very rare and sporadic. I 
captured a female on August 5 in a field on the Purdue Experimental 
Farm (3) near the Lake Erie and Western R. R., at a point where there 
was a fence border growth of elder (Sambucus) and melilotus (1. alba).
