Iii Indiana this modest brown bush cricket has been taken 

 only in the southwestern counties from Terre Haute to the Ohio 

 River, the adults occurring from August to November. In Yigo 

 Co. the first ones discovered were on the slender twigs of some 

 prickly-ash shrubs which grew in a damp upland woods. The 

 place was visited a number of times and the crickets were always 

 found, perfectly motionless, and immediately above or below one 

 of the thorns or prickles jutting forth from the twigs. The tips of 

 the hind femora were raised so as to project above the body, thus 

 causing them to resemble the thorns ; and the color of the insect, 

 corresponding closely to that of the bark, made them very diffi- 

 cult to discover even when in especial search of them. On every 

 clump of prickly-ash in the woods mentioned a number of speci- 

 mens were secured, but they could be found nowhere else there- 

 abouts. A second locality was about the roots of a scarlet oak, 

 (Juerrus coccinea Wang, which grew on a sandy hillside. Here 

 they were plentiful, and resting motionless in the depressions of 

 the bark or beneath the leaves in the cavities formed by the roots 

 of the tree. A pair were also noted in another place on the 

 .flowers of golden-rod. 



Of all the males taken in Indiana but one or two had the teg- 

 mina entire, and usually both tegmina as well as the rudimentary 

 wings were wholly absent, while every female had both pairs un- 

 harmed. I at first ascribed this wing mutilation to the males 

 fighting among themselves, but finally discovered a female in the 

 act of devouring the wings of a male. Why this curious habit on 

 the part of one sex? Possibly the females require a wing diet to 

 requite them for their bestowed affections, or, perchance, they are 

 a jealous set, and, having once gained the affections of a male,
