obtained one specimen, secured in this way on August 12, that lived 

 till the 18th of October and furnished the following notes : 



The physical characters of the captive and some of his attitudes 

 are shown in Figures 10 and 11. His length is 1% inches from the 

 forehead to the tips of the folded wings, the front legs are longer 

 and thicker than in most other members of the family, while the 

 hind legs are unusually short. The antennae, though, are extremely 

 long, slender and very delicate filaments, 2^| inches in length. 

 Between the bases of the antennas on the forehead ther is a small 

 conical projection, a physical character which separates the true 

 katydid from the round-headed katydids and assigns him to the sub- 

 family called the Pseudophyllinae, which includes, besides our species, 

 many others that live. mostly in the Tropics. The rear margins of 

 the wings are evenly rounded and their sides strongly bulged out- 

 ward as if to cover a very plump body, but the space between them 

 is mostly empty and probably forms a resonance chamber to give 

 tone and volume to the sound produced by the stridulating parts. 

 What might be the katydid's waistcoat, the part of the body ex- 

 posed beneath the wings, has a row of prominent buttonlike swell- 

 ings along the middle which rhythmically heave and sink with each 

 respiratory movement. All the katydids are deep, abdominal 

 breathers. 



The color of the katydid is plain green, with a conspicuous dark- 

 brown triangle on the back covering the stridulating area of the 

 wings. The tips of the mouth parts are yellowish. The eyes are of 

 a pale transparent green, but each has a dark center that, like the 

 pupil of a painting, is always fixed upon you from whatever angle 

 you retreat. 



The movements of the captive individual are slow, though in the 

 open he can run rather rapidly, and when he is in a hurry he often 

 takes the rather absurd attitude shown at B of Figure 11, with the 

 head down and the wings and body elevated. He never flies and was 

 never seen to spread his wings, but when making short leaps the 

 wings are slightly fluttered. In preparing for a leap, if only one of 

 a few inches or a foot, he makes very careful preparations, scrutiniz- 

 ing the proposed landing place long and closely, though perhaps 

 he sees better in the dark and acts then with more agility. If the 

 leap is to be made from a horizontal surface he slowly crouches 

 with the legs drawn together, assuming an attitude more familiar 

 in a cat; but if the jump is to be from a vertical support he raises 

 on his long front legs as at C of Figure 11, suggesting a camel 

 browsing on the leaves of a tree. He sparingly eats leaves of oak 

 and maple supplied to him in his cage, but appears to prefer fresh 

 fruit and grapes and relishes bread soaked in water. He drinks 

 rather less than most Orthopterans.
