Only a few species are found in our fauna, 

 three genera: Orocharis, in which both tym- 

 pana of the fore tibiae are present ; Hdpithus, with 

 a tympanum on the inner face only of the fore 

 tibiae; and Tajalisca, with no tympana and no 

 stridulating organs. 



The most common species is Orocharis saltdtor 

 (Fig. 262). This is usually pale reddish brown, 

 but some individuals are grayish. The length 

 of the body is 14-16 mm. It is found from New 

 Jersey west to Nebraska and south to Florida 

 and Texas. 



The only common species of Hapithus is H. 

 agitator, which is found from Long Island west to 

 Nebraska and south to Florida and Texas. 



Our only species of Tafalisca is T. lurida, 

 which is found in southern Florida.

 These are delicate crickets, many of which are Lugger.) 

 of a light green color, with the body and legs 

 sometimes dusky. Figure 263 represents a male; in the females the 

 front wings are miore closely wrapped about the body, giving the insect 

 a narrower appearance. They live in more or less elevated positions, 

 varying, according to the species, from among herbaceous plants to 

 the higher parts of fruit and forest trees, hence the name tree-crickets 

 commonly applied to them. Their frequent occurrence among flowers 

 suggested the name of the principal genus, CEcdnthus, implying / 

 dwell in flowers. Two genera of tree-crickets are represented in our 

 fauna, Neoxabea and CEcanthus; these can be distinguished by differ- 

 ences in the armature of the hind tibiae. 



Neoxdbea. — In this genus the hind tibi« bear 

 neither teeth nor spines except the apical spurs, 

 and the first segment of the antennas is armed in 

 front with a stout, blunt tooth (Fig. 264, h). 

 Neoxdbea bipunctdta is the only species known. 

 In this species the hind wings are almost twice as 

 long as the fore wings; the fore wings of the fe- 

 male are each marked with two rather large 

 blackish spots; the wings of the male are un- 

 marked. The general color is pale pinkish brown. 

 The length of the body is about 16 mm. 



QLcdnthus. — In this genus the hind tibiee bear 

 both spines and teeth. Several species occur in 

 the United States and Canada ; these differ in the 

 color of the body, in the markings on the first two 

 segments of the antennae, in their song, and in the
