In Indiana this cricket has as yet ])cen taken only in Vigo County, 

 and during the montli of September. 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 nnmber of times and 

 the crickets were always found, perfectly motionless, and immediate- 

 ly above or below one of the thorns or prickles jutting forth from the 

 twigs. The ti])s of the hind femora were raised so as to project above 

 the body, thus causing Ihcm to resend)le the thorns; and the color 

 (>f the insect, corresponding closely to that of the bark, made them 

 very difficult to discover even when in especial search of them. On 

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

 gppf.ii-.ioiic wor(> secured, but they could be found nowhere else there- 

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

 (Jueiriis nicriiira Wang, which grew on a sandy hillside. Here they 

 were plentiful, and resting motionless in the depressions of the bark 

 or ])eneath the heaves 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 nuiles taken, over thirty in number, there was not one 

 M'ith i)erfect wing covers, and, in almost every instance, the wing pov- 

 ers as well as the rudimentary wings were wliolly absent; while every 

 female had holli pairs unarnu'd. 1 at first ascribed this wing mu- 

 tilation lo the nuiles fighting among themselves, but finally discov- 

 ered a female in the act of devouring the wings of a nuile. 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, per- 

 chance, they are a jealous set, and, having once gained the affections 

 of a male, devour his wing covers to keep him from calling other 

 females about him. Quien sahe? 



It is more than probable, howc'ver, thai tlu' mating of the sexes 

 takes place in a similar manner to that of the striped tree cricket 

 (Ecanthus fasciulus Fitch, described above; the females gnawing away 

 the tegmina of thy males in order to more readily reach some seminal 

 glands which lie beneath. The openings of these glands, located on 

 the dorsum of the mesothora.v, are visil)le in dried specimens at hand.
