and cultivated fields and meadows. It also occurs on sunny slop- 

 ing hillsides and railway embankments. In fact, mature individ- 

 uals may occur anywhere in dry grassy places from mid-April till 

 November 1st. In such localities the young, in company with 

 those of ArjtJiid xulirtmrcii. may be seen on all sunny winter days 

 when the mercury is above the freezing point. At such times they 

 often climb or lea]) upon the lower rails of fences or sides of 

 stumps, there resting in and apparently enjoying the sunshine. 

 The species is said to be double brooded in some localities, but in 

 Indiana, as far as known, it is single brooded, the young hatching 

 in August and September and undergoing three or four moults be- 

 fore winter. 



In .Minnesota Somes ( 1!>14, 40) says of it: "Excluding the 

 Tctt if/id a\ C. riri<lif<i>-i<it<i may be considered our Orthopteron 

 'harbinger of spring,' being normally the first locust to appear as 

 adult. We have noted it in some numbers near Minneapolis as 

 early as April 1, while in Iowa we have taken it a month earlier. 

 It is apparently double-brooded, as we have found the young 

 swarming in lowland meadows as early as June 2(> and again in 

 September." 



Of the egg-laying habits of riridifdwidtft Hancock (1911, 410) 

 writes: "At Millers, Ind., June 5, I found a female laying her 

 eggs in dam]) sand at the border of a pond. When I approached 

 she had her abdomen buried quite deeply. After 15 minutes she 

 moved away from the place. I carefully unearthed the burrow, 

 finding it to be 27 mm. deep, and at the bottom, the eggs, 25 in 

 number, were laid in a compact mass. They were bound together 

 with a white mucous, and there was quite an amount of this sub- 

 stance lying above the eggs in the burrow." 



This green-striped or dusky locust is one of the most widely 

 distributed of North American Oedipods, its known range includ- 

 ing the New England states and southern Ontario and extending 

 west to Moose Jaw, Sask., Minnesota and northern Colorado, and 

 south and southwest to Georgia, Oklahoma and Texas. Morse 

 (1!)OT, :>4) calls it ''one of the most ubiquitous locusts of the east- 

 ern half of the continent, inhabiting a great variety of environ- 

 ments, chiefly campestral and on soil containing a moderate 

 amount of moisture. It is one of the few species which has ap- 

 parently extended its range down the Mississippi River along the 

 levees, being common on the higher ground near the river and on 

 embankments along canals." 



In Indiana, as elsewhere throughout its range, green females 

 and brown males are the predominating forms, not more than 20
