ACRYDIIDAE 

 ACRYDIINAE 



Nomotcttix cyistatns, probably subspecies cristatus (Scudder).* 

 Warren Woods, September 7, 1920, 2 immature specimens. 



Swept- from low, dn^ grass on the cleared upland of the 

 Warren Woods Preserve, in an area where much bare ground 

 and small patches of dry moss are exposed among the scant 

 vegetation. No adults could be found. 



Acrydium granulatum Kirby. 



Warren Woods, September 3, 1919, i female. 



Sawyer Dunes, June 24 to August 31, 1919, 2 males, 4 females; July 

 II, 1920, I male, i immature specimen. 



This species was taken in a moist meadow pasture near the 

 Warren Woods Preserve ; also from the borders of some of 

 the dune ponds, on the bare sandy and muddy margins, among 

 the herbage covering the higher parts of the shores, and among 

 the low ground herbage under the surrounding thickets. It 

 does not seem to be common in the county, though in other 

 parts of the state it appears to be the most abundant species 

 in the genus. 



Acrydium ornatum Say. 



Warren Woods, June 25 to July 2, 1919, 5 males. 



Taken on a sandy clay road at the edge of a patch of second 

 growth forest, in company with A. hancocki (see below) ; 

 also found on nearly bare, trampled areas of dried mud about 

 the margins of the water-holes frequented by the cattle, on 

 the banks of the Galien River. Specimens were taken on the 

 river's moist sandy margins, among the herbage of the mud- 

 bars, and by sweeping the grass on a wet, springy hillside
