Melanoplus amplectens Scudd. 



This locust and nymphs doubtfully regarded as of the same 

 species were taken from the ground, mainly among leaves, in the up- 

 land forest (Sta. IV, a) Aug. i6 (No. 67) ; other collections are as 

 follows: in the glade in the lowland forest (Sta. IV, c) Aug. 20 (No. 

 117) ; on the open ravine slope (Sta. IV, b) Aug. 22, a male (No. 

 124a) ; and on the same date, in the glade of the lowland forest (Sta. 

 IV, c), a nymph and an adult female (No. 143). 



This is the largest of the short-winged locusts in the forest, and 

 an abundant species. Morse ('04, pp. 19, 50, PI. 7) described its 

 haunts as in thickets, forest margins, open forests, and occasionally 

 in grassy clearings and fields. 



Melanoplus gracilis Bruner. 



Two males were found Aug. 20 in a glade in the lowland forest 

 (Sta. IV, c) where there was a luxuriant cover of vegetation, and 

 nettles and Bupatorium ccolestinum abounded; and Aug. 22, in the 

 same location, one female was found (No. 143). 



The wings are very rudimentary in this species. Hart ('06, p. 

 82) describes its habitat as follows: "On tall grasses and weeds in 

 ravines and about marshes, masses of wild vines along railroads, 

 weedy growths in the beds of small streams, and in like situations." 

 These conditions are found in open areas with an abundance of vege- 

 tation. 



Melanoplus ohovatipennis Blatch. 



This small species, similar to scudderi, was found in the upland 

 forest (Sta. IV, a) Aug. 17 (No. 93). A nymph taken Aug. 22 

 from the forest (Sta. IV) is doubtfully regarded as of this species 

 (No. 124). 



Hart ('06, p. 81) gives the habitat of this species as "High 

 wooded hillsides throughout Illinois." Blatchley ('03, p. 308) states 

 that it frequents '"for the most part, high, dry, open woods, espe- 

 cially those in which beech and oak trees predominate." He further 

 states that in a dry season it may be found associated with Dichro- 

 morpha viridis and TruxaUs hrevicornis "among the reeds and tall 

 rank grasses near the borders of marshes." 



Melanoplus scudderi Uhl. Scudder's Grasshopper. 



A single female was found in the open glade in the lowland for- 

 est (Sta. IV, c) Aug. 20 (No. 117) ; and a nymph taken Aug. 22 

 from the open ravine slope ( Sta. IV, & ) is doubtfully referred to this 

 species (No. 124).
