Furcata occurs in all portions of the State, having been taken in 

 every county where collections have been made. Its general range 

 includes the United States and southern Canada east of the Great 

 Plains. In central and southern Indiana the first mature specimens 

 appear about July 15th, but they do not become plentiful before the 

 first of August, and I have seen the nymphs in Vigo County as 

 late as September 18th. It is most frequently seen on the low 

 bushes and trees about the margin of thickets and along fence rows, 

 but in the prairie country north it frequents coarse grasses and weeds 

 in company with the preceding species. Its flight is noiseless and 

 seemingly without direction, and is not so prolonged as that of S. 

 texensis. I have seen the adult of this species captured and borne 

 away by the sand wasp. 



Dr. C. V. Eiley (loc. cit.), gives the following account of the egg 

 laying habits of furcata; "The female stations herself firmly by the 

 middle and hind legs on twigs or leaves contiguous to the one selected 

 to receive the eggs. This leaf is then grasped by the front feet and 

 held in a vertical position, while the edge is slightly gnawed or pared 

 off by the jaws to facilitate the entrance of the point of the oviposi- 

 tor. When this is done the abdomen is ctirved under and brought 

 forward, and the ovipositor is seized on its convex edge by the mandi- 

 bles and maxillae, which, with the aid of the palpi, guide the point to 

 that portion of the leaf prepared to receive it. After gentle, but 

 repeated efforts, the point of the instrument is finally inserted be- 

 tween the tissues of the leaf, and gradually pushed in to more than 

 half its length. As soon as the cavity is formed, the egg is extruded, 

 and passed slowly between the semi-transparent blades of the ovi- 

 positor. As the egg leaves the. ovipositor the latter is gradually with- 

 drawn, while the egg remains in the leaf, retained in place, probably, 

 by a viscid fluid that is exuded with it. As many as flve of the eggs 

 are sometimes deposited in one row in the same leaf, but more often 

 they are single. 



Of the call note of furcata Riley also states: "The shrill of the 

 male is by no means so loud as that of the oblong-winged katydid, 

 AmUycorypha oblongifolia DeGeer, in which its sound is always 

 drowned in the woods. It consists of a softer zeep, zeep, sometimes 

 uttered singly, but generally thrice in succession. The call is occa- 

 sionally responded to by a faint chirp from the females, produced by 

 stretching out their wings as if for flight, and is as often heard in 

 the day as at night."
