ground in short blue grass and Poa compre^sa areas in dry fields and 

 along 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 (Seudder). 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 6, 

 few seen in a dry grassy area, largely occupied by Andropogon fureatus, on 

 a wooded slope (10) near Wild Cat Creek. 



Dissostelra Carolina (Linnaeus). 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 amerieana (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 (3) ; October 12, a male observed in bunch grass, An- 

 dropogon fureatus, 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).
