102 AN INTRODUCTION TO ENTOMOLOGY. 



abdominal segment. The color of these insects is brown, sometimes 

 marked with minute dark specks. 



This species is an excellent 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-palmettoes ; and so 

 closely 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 States are two species of the genus St enobot Ji- 

 ms. 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 foveolae ; 

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

 common of the two is the Short-winged Locust, 5. curtipennis. 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 are longer. 

 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 spotted-winged 

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

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

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

 its whole extent ; sometimes the inner halves of the tegmina are 

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

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

 size as the preceding. 



In the genus Clirysochraon the vertex is without foveolae; and 

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

 species, the Sprinkled Locust, C. conspcrsiim, is very abundant. It 



is 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 teg- 

 mina of the female sprinkled or mot- 

 Fig. yi.—chrysochraon conspersum. tied with darker brown . The tegm ina 



and wings are a little shorter than 

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

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

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