are the areas of second growth scrub to be found in the vicinity 

 of the Warren Woods and elsewhere in the region. In the 

 cleared areas on and about the Warren Woods Preserve small 

 trees and brush have grown up to form thickets and open scrub 

 in many places along the edges of the ravines and in the 

 cleared flood-plain and ravine bottoms. The trees are chiefly 

 young oaks, maples, and hawthorns ; the shrubbery is com- 

 posed of a large number of species differing with each indi- 

 vidual locality. Conspicuous among these are blackberry and 

 raspberry (in many places the dominant forms), rose, spice 

 bush {Benzo'm acstivalc (L.) Xees.), dogwood (Cornus sp.), 

 witch-hazel {Hainainclis virgimana L.), and bladder nut 

 (Staphylca trifolia L.). Among the trees and shrubs the 

 ground is usually covered by tall grass and weeds, dry during 

 the greater part of the season. 



It will be seen that a rather wide variety of environmental 

 conditions has been grouped under this head ; they seem, how- 

 ever, to be essentially similar when regarded as Orthopteran 

 habitats. Though nearly equalled by that of the sedge marsh, 

 the number of species of Orthoptera found in the upland 

 thicket and scrub habitat exceeds that of any of the other 

 habitats of the region. The following is the list of the species 

 taken here :
