This species is so distinctly arboreal and nocturnal that I was sur- 

 prised to find it stridulating during the day, and so near the ground. 

 I have camped for days in a grove where these insects made a great 

 din at night, but found none on the low vegetation or on the ground 

 (as at Kappa, 111). Years ago a large colony flourished in Franklin 

 Park at Bloomington, 111. 



€onocephalus nehrascensis Bruner. Nebraska Cone-nose. 



A female was taken in the glade in the damp lowland forest ( Sta. 

 R^ c) Aug. 20 (No. 117). 



The female of this species has been observed to oviposit "between 

 the stem and root-leaves of Andropogon" , a typical prairie plant, but 

 little appears to be recorded of its habitat. A large nymph of this genus, 

 and probably of this species (No. 159), was taken on the prairie 

 grass Andropogon (Sta. I, g) Aug. 24. It had been captured by the 

 crab-spider il!fmfm<?wa a/<?afona Hentz (No. 159). 



Orchelimum cnticidare Redt. 



A specimen was taken in the upland forest (Sta. IV, a) Aug. 16 

 (No. 67) ; another, from the open areas of the upland forest (Sta. 

 IV, a) Aug. 17 (No. 93) ; and a third, from the glade in the damp 

 lowland forest (Sta. IV, c) Aug. 22 (No. 143). All of these were 

 males. 



OrcJicUjunin glaherriimnn Burm. 



This insect was found in abundance in the glade in the lowland 

 forest (Sta. IV, c) Aug. 20 (No. 117), and a nymph was taken in 

 the same place Aug. 22 (No. 143). 



The abundance of this species in this damp area, with its pro- 

 fusion of low vegetation, indicates that the conditions were fav- 

 orable. 



Xipliidium nemoralc Scudd. 



Nymphs and adults were found in the glade in the lowland for- 

 est (Sta. IV, c) Aug. 20 (No. 117) and Aug. 22 (No. 143) ; in the 

 openings in the upland forest (Sta. IV, a) Aug. 17 (No. 93), and 

 Aug. 20 (No. 103). 



Blatchley ('03, p. 374) states that it abounds along the "borders 

 of dry, upland woods, fence rows, and roadsides, where it delights to 

 rest on the low shrubs, blackberry bushes, or coarse weeds usually 

 growing in such localities."
