102 AN INTRODUCTION TO ENTOMOLOGY.

This spi llcnt illustration of protective form and 



coloring. I found it quite common in Florida upon the " wire- 

 grass" which grows in the sand among the saw-palmettos : and so 

 ly did their brown linear bodies resemble dry grass, that it was 

 very difficult to perceive them. 



I have also collected this species near the coast as far north as 

 Maryland, but have no other information as to its distribution. 



Among the more common representatives of this sub-family in 

 the Eastern United are two species of the genu- ,>///- 



rns. In each of these there is on each side on the margin of the 

 vertex in front of the eye a little oblong pit, the lateral Fo 

 and the lateral carinae of the pronotum are incurved. The more 

 common of the two is the Short-winged Locust, .V. iiirtipi-nnis. In 

 this species the lateral foveolae are linear; the tegmina are unspotted 

 and of a pale reddish brown. In some specimens the tegmina and 

 wings are shorter than the abdomen ; in others they arc Ion 

 The males measure about 16 mm. (0.63 inch) in length ; the females, 

 21 mm. (0.82 inch). 



The next species of this genus in abundance is the spottcd-wi: 

 locust, 5. maculipcnnis. In this species the lateral foveolae are shal- 

 low, and broader towards the eye than at the apex; the tegmina 

 green, with a median band of equidistant square black spots along 

 whole extent; sometimes the inner halves of the tegmina are 

 entirely of a rust-red color. Both the tegmina and wings extend 

 nd the tip of the abdomen. This species is about the same 

 si/.e as the preceding. 



In the genus Chrysochraon the vertex is without foveolae; and 

 the lateral carinae of the pronotum are nearly parallel. One of the 

 the Sprinkled Locust, C. conspfrsum* is very abundant. It 

 N brown, with the sides of the prono- 

 tum and the first two or three abdo- 

 minal segments shining black in the 

 male , and with the body and 

 mina of the female sprinkled or mot-

and win a little shorter than 



the abdomen in the males, and much shorter in the females. The 

 female is represented by Fig. 92. The malo measure 17 mm. (0.67 

 inch) in length; the females, 23 mm. (0.91 inch).
