"clacking." The species of Hippiscus are heavy, broad-bodied forms 



with wings reddish or yellow- 

 ish at base, then a broad black- 

 ish band, and the apex and 

 margin clear. The fore wings 

 and body are yellowish to 

 brown, with darker blotches 

 and speckles. H. discoideus, 

 with wings red on basal half, 

 is common in the East. H. 

 tuberculatus (Figs. 179 and 180), 

 the coral-winged locust, or king 

 grasshopper, also with red 

 wing-disks, is common in the 

 Mississippi Valley ; it makes 

 a very loud rattling while in 

 the air. The genus Arphia, 

 also characterized by wings 

 with bright red or yellowish 

 disks but having the fore wings 

 without large spots or blotches, 

 usually not even speckled, and 

 with the body slenderer than 

 in Hippiscus, comprises about 

 twenty species scattered over 

 the whole country. A. xan- 

 thoptera, with plain smoky 

 brown fore wings and upper 

 body, and hind wings with 

 bright yellow disk, broad smoky 

 outer band and clearer apex, 

 is common in the East; A. 

 tenebrosa (Fig. 183), with brown 

 and clayey-speckled fore wings 

 and upper body and hind 

 wings with coral-red disk and 

 smoky broad outer band fad- 

 ing out in apex, is common 

 in the West. The green- 

 striped locust, Chortophaga
