male, just before copulating, was heard to stridulate briefly 

 and jerkih', with a very rapid vibration of the hind femora, 

 as if intensely excited by the final acts of courtship. 



Though not uncommon, specimens of this species were not 

 easy to secure. Their form and coloration make them very 

 inconspicuous objects among the brown grass and sedge stems, 

 and their habit of dropping to the ground and hiding among 

 the bases of the grass and sedge clumps when alarmed much 

 increases the difficulty of finding them. The adults were 

 apparently just becoming numerous on July 16, as two last 

 stage nymphs were taken on this date, and several of the 

 adults were teneral. By September 7 the species had l>ecome 

 scarce. 



Orphiilella spcciosa (Scudder).^^ 



Warren Woods, July 4, 1919, 5 immature specimens; September 7 



1920, 13 males, 6 females. 

 Sawyer Dunes, July 18 and 25, 1920, 2 macropterous females. 

 Three Oaks, September 4, 1920, i male. 



Abundant on the dry, grassy upland fields on the Warren 

 Woods Preserve. One male was taken in a similar habitat 

 near Three Oaks, and two females, with tegmina and wings 

 of exceptional length, were taken by Hussey in the beach drift. 

 This series exhibits a striking amount of diversity in colora- 

 tion and pattern.

New Buffalo, September 2, 1919, 8 males, 6 females ; September g, 

 1920, I male, i female. 



Rather common in the drier margins of the lizard's tail
