toms near West Lafayette (6); September 13, a male taken in a swamp 
border thicket in low woods on Burnett Creek (2). 
Amblycorypha oblongifolia (DeGeer). Only a single specimen, a male, 
was taken on the night of July 25 in a grove of young silver maples at a 
nursery two miles southeast of Lafayette. The species is, however, much 
more frequent than the single capture would indicate since its notes were 
frequently heard at night throughout midsummer. 
Amblycorpha rotundifolia (Scudder). A female specimen was taken 
July 12 in a patch of Elymus virginicus in a narrow fringe of woodland at 
the base of the bluff on the outer edge of the Wabash bottoms below West 
Latayette (6). 
Microcentrum laurifolium (Linneus). This, or the related species, 
retinerve, appears to be common in trees at Lafayette since its notes were 
heard continuously throughout late July and August. Only one specimen 
was actually taken and identified as belonging to laurifolium.* It flew 
into the office at the Experiment Station. 
Neoconocephalus robustus crepitans (Scudder). Late in August three 
males were heard stridulating in the corn plats on the Purdue University 
Farm (3) and on the evening of August 26 two of these were captured, 
one being taken in some crab grass (Syntherisma sanguinalis), the other 
on a corn tassel. According to Blatchley this species has hitherto been 
noted in Indiana only in Laporte County along the shore of Lake Michigan. 
Neoconocephalus palustris (Blatchley). Of regular occurrence in 
open Homalocenchrus oryzoides bogs, but not especially frequent. 
August 20, one male, two females, in Homalocenchrus oryzoides bog 
at base of bluff on Wabash bottoms near West Lafayette (6); August 30, 
a female taken in mixed Scirpus americanus and Homalocenchrus oryzoides 
on low banks of the Wabash River opposite Battle Ground (16); Sep- 
tember 6, one specimen of each sex taken in Homalocenchrus oryzoides 
bog at base of bluff near Wild Cat Creek (10). 
Orchelimum vulgare Harris. Abundant everywhere in tender succu- 
lent grasses; uncommon in woodland situations. 
July 22, males and nymphs abundant in growth of Chetochloa viridis 
on a waste lot of the Purdue Experiment Farm (3); August 9, one male 
and a female taken in woodland bog in low woods on Burnett Creek (2), 
far from common here; August 20, common in Homalocenchrus oryzoides 
at base of bluffs along margin of the Wabash bottoms near West Lafayette
