KATYDIDS AND THEIR KIN. 453 



scribed from specimens taken at Dallas, and the Gulf Coast of 

 Texas and in Arizona. It has since been taken east of the Mis- 

 sissippi at Lake Drmnmoiid, Dismal Swam]), Va., Southern Pines, 

 N. Car., Stone Mountain. Ga., and in Walton Co., Fla. These 

 records are given by K. & H. (11G, 1247) who state that the 

 Florida specimen was "taken from the stomach of a turkey killed 

 in a pine forest," while the single Georgia specimen was "found 

 in a dusty road bordered on each side by heavy pine woods."

KATYDIDS AND THEIR KIN. 



"I sit among the leaves here, when evening's zephyrs sigh, 

 And those that listen to my voice I love to mystify; 

 I never tell them all I know, altho' I'm often bid, 

 I laugh at curiosity, and chirrup, 'Katy did.' ' 



The family Tettigouiidie comprises those insects commonly 

 called katydids, green or long-horned grasshoppers, cone-headed 

 grasshoppers and stone or camel crickets, the name "grasshopper'' 

 rightfully belonging to its winged members and not to the short- 

 horned locusts or Acrididre. The principal distinguishing char- 

 acters of the members of the family Tettigoniidre, as given in the 

 key, j). 149, are the long, slender, tapering, many-jointed antenna 1 

 which, when turned back, usually extend far beyond the tip of 

 abdomen; almost universal absence of ocelli or simple eyes; the 

 four-jointed 62 tarsi or feet; and the sword-shaped or falcate ovi- 

 positor of the females, which is made of four flattened plates 

 with the edges near its tip often horny and serrate. The head 

 in many of the species is wedge-shaped and the mouth-parts are 

 well developed, the maxillary palpi being very long and the man- 

 dibles especially long and sharp-pointed. This enables the insect 

 to dig into plant tissue or to eat the seeds of grasses, as many of 

 them do. The teguiina, when present, are usually leaf-like and of 

 a delicate structure, having no stiff chitinous anterior veins. 

 When closed the left one usually overlaps the right, and, in the 

 larger forms, they slope obliquely downwards instead of being 

 bent abruptly, as in the Gryllidne or true crickets, while in most 

 cases, the wings are slightly longer than the tegmina. The meso- 

 and hietathorax are less closely united than in the Acrididse, 



6I This family of the suborder Saltaloria was for many years known as Locustid"e. 

 but the genus Locnsta of Linnreus was founded for a true locust and not for a katydid, 

 hence recent American writers have used the name Tettigoniidre, which is based upon the 

 Linnasan genus Tettigonia, given to a European katydid and meaning "grasshopper" and 

 "angle," on account of the shape of the tegmina. In Europe Kirby and some of the other 

 writers use the family name Phasgonurid;t for the same insects, while Karney and others 

 still retain "Locustidre." 



62 The members of the genus Daihinia, no one of which occurs in our territory, have 

 the fore and hind tarsi three-jointed.
