(6) ; August 28, common in tall roadside vegetation, about ditches, etc., 

 at West Lafayette ; September 4. abundant in mixed growth of Muhlen- 

 bergia sp. and Chcetochloa viridis in a neglected field at West Lafayette; 

 September 6, common in Homalocenchrus oryzoides bog and in adjoining 

 weed areas at base of the bluffs near Wild Cat Creek (10) ; September 13, 

 small numbers observed in swamp border thickets in low woods on Bur- 

 nett Creek (2) ; October 13, rather scarce at West Lafayette (3). 



Orchelimum vulgare, long-winged phase. This is the form which has 

 coininonly been called glubcrrimum by Blatchley and the majority of re- 

 cent writers. Rehii and Hebard, however, have recently reached the con- 

 clusion that this term correctly applies to the entirely different red-faced 

 Orchelimum of the Middle and South Atlantic States which Davis has 

 called erythrocephalum and which I have so designated in my paper on 

 New Jersey Orthoptera. In the last-mentioned work the form termed 

 glaberrimum has since been recognized to be a distinct species which Rehii 

 and Hebard are about to describe. Occurs in the same situations as the 

 preceding species, but is much less frequent though by no means un- 

 common. 



July 22, a male taken in patch of Chcetochloa viridis in a waste lot 

 on the Purdue Experimental Farm (3) ; August 20, a male and female 

 taken in a Homalocenchrus oryzoides bog at the base of the bluffs on the 

 edge of the Wabash bottoms near West Lafayette (6) ; August 24, a male 

 taken in com plat at Purdue Experimental Farm (3) ; August 28, several 

 males observed at night while stridulating on young trees and tall herbs 

 on the bluff at the head of Happy Hollow (5) ; September 4, one female 

 taken in thick grass on a neglected lot at West Lafayette ; September 6, 

 a male taken in Homalocenchrus oryzoides at base of bluff near Wild Cat 

 Creek (10) ; October 4, several seen on Purdue University Farm (3). 



Orchelimum gladiator (Bruner). Only two specimens, both males, 

 taken during the season. Both were found in bottom lands in thick 

 grass. 



July 12, a male taken in a Homalocenchrus oryzoides bog at the base 

 of the bluff on the outer edge of the Wabash bottoms below West Lafay- 

 ette (6) ; July 19, a male taken in a thick growth of Elymus virginicus 

 on the east bank of the Wabash at the mouth of Wild Cat (11). Profes- 

 sor Blatchley kindly verified my determination of these specimens. 



Orchelimum agile (DeGeer). A single individual (female) was taken
