Il8 AN INTRODUCTION TO 



8. Scudderia. The Narrow-winded Katydid, Scuddcria cum- 



union species of tin's genus. It is quite abundant in 



many parts of the country. The tegmina are long ami narrow, 



hence the common name. The cies "are laid singly 



in the i :>etween the upper ami lower cuticles, ami 



'.iin that they are not noticeable except when the leaf is held 



between one's self and the light. They swell very considerably, 



however, in the spr: re hatching." i RiK

9. Thyrconotus. These are windless, dull-cilored grasshoppers 

 which offer a striking appearance, owing to the great sixe of the pro- 

 notum. This segment is so enlarged as to extend back over the 

 other two thoracic segments. The ovipositor of the female is also 

 greatly developed, and is nearly straight. \Ve have in the eastern 

 half of the United States two widely-spread species. T. dorsalis has

the pronotum well rounded behind. In T. pacliv merits (Fig. 106) 

 it is nearly square. The hind legs and ovipositor are longer in /'. 

 dorsalis than in the other species. 



In the region west of the Mississippi River are found wingless 

 -hoppers which are known as " Western crickets." These be', 

 to the genus Anabrns. This genus resembles Thyrconotus in the 

 shield-like pronotum and the large sixe of the ovipositor, but dii 

 in having the prosternum unarmed, while in the former genus there 



two spines between the base of the front legs. Thn 

 Anabrus have been described. " . /. eoloradns is the smallest, and 

 ha-, the abdomen distinctly marked by transverse bands; A. purpu- 

 dark purplish brown, mottled with yellow; A. simplex, dark- 

 shining brown. This species varies considerably in color, being 

 found of every shade from light brownish yellow to almost entirely 

 black; specimens are sometimes found that are partly yellow and 

 partly black or dark purple." A. simplex is sometimes very destruc- 

 tive to crops.
