tall weeds and bushes, in tall grass in fields and pastures, in 

 corn and wheat fields, and in lizard's tail and sedge marshes.. 

 The stridulation of this species is a rapid zzik-zzik-zzik-zzik 

 repeated with monotonous regularity, except for an occasional 

 break, as if it had missed fire, and immediate recovery with- 

 out change of rhythm. On one occasion a specimen was heard 

 to utter a series of fifty-four notes in succession ; and others 

 were heard to stridulate for much longer periods. The song 

 is rather loud, and when heard close at hand has a distinct 

 metallic ringing quality. Early in the evening the insects are 

 quite wary, stopping their song when approached within six 

 or eight feet ; but after dark it is pos3*lble to come within a 

 foot or two of a stridulating individual without disturbing it. 



One specimen of a light straw color was taken near Three 

 Oaks ; all of the others were of the green phase. Immature 

 specimens, perhaps of this species, were taken between July 

 3 and lo at the Warren Woods, Lakeside, and in the Sawyer 

 Dunes. Hancock has recorded finding this species at Lakeside.

One male was taken among a growth of tall, dry grass and 

 dewberry vines on the sides of a railroad embankment just 

 behind the dunes at New Buffalo; and a female was found 

 among the low undergrowth of grass and small herbaceous 

 plants in an open oak forest on a sandy ridge half a mile from 

 the lake. One other specimen was seen in a small collection 

 made in the dune region in the vicini'ty of Harbert by Mr. 

 W. R. Hibbs. Several nymphs which may belong to this spe- 

 cies were taken in the Sawyer Dunes during July among the
