low woods on Burnett Creek (2) ; October 13-14, 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 orysoides, Garex spp., Scirpus atrovirens, 

 Sagittaria sp., Salix thickets, etc., in low woods on Burnett Creek (2) ; 

 September 13, a female taken in a bog border thicket in the same locality 

 (2), associated with M. obovatipennis. 



Melanoplus fasclatus (Walker). Probably quite rare. A single male 

 specimen was taken June 28 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 Pcmicum huachucce and a few other forms not deter- 

 mined. My determination of this specimen was kindly verified by Prof. 

 Blatchley. 



Melanoplus loalshii Scudder (M. Blatclileyi Scud.). Only a single 

 specimen, a female, was taken July 19 in a dense growth of Elymus vir- 

 glnicus on the flood 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 woidd 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-
