low woods on Burnett Creek (2); October 15-14, frequent in herbaceous 
thickets (asters, goldenrod, ragweed, etc.) surrounding a cat-tail marsh on 
the upland northwest of West Lafayette (14). 
Melanoplus gracilis (Bruner). Apparently moderately frequent locally 
in moist or slightly humid woodland locations, frequenting grassy and 
sedgey tangles and herbaceous thickets in the vicinity of bogs. 
July 27, males moderately frequent in grassy and sedgey areas and 
surrounding thickets in humid upland woods northwest of West Lafayette 
(1); August 9, adults of both sexes found in small numbers in a bog 
occupied by Homalocenchrus oryzoides, Carer spp., Scirpus atrovirens, 
Saygittaria sp., Salix thickets, ete., in low woods on Burnett Creek (2) ; 
September 13, a female taken in a bog border thicket in the same locality 
(2), associated with J/. obovatipennis. 
Melanoplus fasciatus (Walker). Probably quite rare. A single male 
specimen was taken June 2S in an exceptionally dense bit of woodland 
near the base of a steep bluff not far from the mouth of Indian Creek 
(15). The ground where it was taken was quite bare, except for a few 
scattered plants of Panicum hudchuce and a few other forms not deter- 
mined. My determination of this specimen was kindly verified by Prof. 
Blatchley. 
Melanoplus walshii Scudder (M. Blatchleyi Scud.). Only a_ single 
specimen, a female, was taken July 19 in a dense growth of Blymus vir- 
ginicus on the fiood plain of the Wabash near the mouth of Wild Cat 
Creek (11). 
Melanoplus atlanis (Riley). Abundant, though somewhat local, in 
open grassland in relatively dry situations. Most frequent in upland 
localities, but it also occurs in small numbers in the bottoms wherever the 
conditions allow the formation of dry grassland. The species reaches 
maturity the latter part of June and persists through the summer and well 
into the fall. The adults appeared to be most abundant about July 20; 
they apparently decreased in numbers in late summer and early Septem- 
ber, but in some places they seemed to increase again in early October. At 
the latter period a number of copulating pairs were taken and the individ- 
uals were found in localized groups, facts which would perhaps indicate 
the recent maturing of the specimens and the possibility of a second or 
fall brood of adults. It is conceivable at least that some of the earlier laid 
eggs might under favorable conditions hatch out in the fall and thus pro-
