ORTHOPTEKA OF INDIANA. 



439 



In Indiana pennsylv aniens, for the most part, survives the winter 

 in the nymph stage, the yonng, on the approach of cokl weather, 

 making for themselves cone-shaped cavities an inch or two across 

 the top and about as deep, iu the mold beneath decaying logs and 

 rubbish. Sometimes the margins of these burrows are surrounded 

 by fragments of grass stems and pieces of decaying leaves. In warm, 

 sheltered localities, some individuals evidently reach maturity in late 

 autumn or early winter; a full grown, freshly moulted female having 

 been taken in a greenhouse in Marion County, on December 14Lh. 

 The males begin to pass their final moult in central Indiana about 

 May 15th, and from then on through June and July the open woods 

 pastures and the angles of old rail fences echo with the music of 

 their song. The young hatch in July and August, and after the 

 second or third moult form their winter abiding places, while the 

 adults perish with the coming of the hoar frost. 



Pennsylvanicus occurs throughout the State and is said by Scudder 

 to range across the continent. The long winged form is much less 

 common than- the short winged and is seldom met with in the field; 

 but may often be found about electric and other lights during the 

 summer nights. However, on two occasions in June, I have taken a 

 long winged male in company with two short winged females be- 

 neath logs.
