toms near West Lafayette (6) ; September 13. a male taken iu a swamp 

 border thicket in low woods on Burnett Creek (2). 



Amblycorypha oblongifolia (DeGeer). Only a single specimen, a male, 

 was taken on the niglit of July 23 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 rotmidifolia (Scudder). A female specimen was taken 

 July 12 in a patch of El am us virginicus in a narrow fringe of woodland at 

 the base of the bluff on the outer edge of the Wabash bottoms below West 

 Lafayette (6). 



Microcentrum laurifolium (Linnaeus). 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. 



Neooonocephalus rooustus 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 (Syntlwrisma sdnguinalis), 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). 



Orehelimum vulgare Harris. Abundant everywhere in tender succu- 

 lent grasses ; uncommon in woodland situations. 



July 22, males and nymphs abundant in growth of Chcetochloa 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
