ORTHOPTERA

cies, the Carolina leaf-roller, Camptondtus carolinensis (Fig. 256), 

 occurs in our fauna. This species is wingless; it measures from 

 13 mm. to 15 mm. in length. Its known range extends from New- 

 Jersey west to Indiana and south to Florida. 



This insect is very remarkable in its habits,which have been de- 

 scribed by Caudell ('04) and McAfee ('08). It makes a nest by 

 rolling a leaf and fastening the roll with silken threads which it 

 spins from its mouth. It remains in its nest during the day and 

 emerges at night to capture aphids upon which it feeds. 



Subfamily RHAPHIDOPHORIN^ 



The Cave-Crickets or Camel-Crickets 



Many common names have been applied to members of this sub- 

 family; SLxnong these are cave-crickets, because they abound in caves 



and are found in other 

 dark places; camel-crick- 

 ets, because of the high, 

 arched back of some 

 species (Fig. 257); and 

 stone-crickets, from their 

 habit of hiding beneath 

 stones. This last name 

 is not at all distinctive. 

 These are wingless 

 long-horned grass- 

 hoppers that bear some 

 resemblance to the true 

 crickets (Fig. 258). They have a short, thick body and remark- 

 ably stout hind femora, like a cricket, but are entirely destitute 

 of tegmina and wings, and the females, like other Tettigoniidse, have 

 a sword-shaped ovipositor. The more common species are either of 

 a pale brown or a dirty white color and more or less mottled with 

 either lighter or darker shades.

These insects live in dark and moist places, under stones and 

 rubbish, especially in woods, in cellars, in the walls of wells, and 

 in caves. On one occasion I saw many thousands of them on the 

 :oof of a cave in Texas. 



Caudell ('16) in his monograph of this subfamily lists twelve gen- 

 era including many species that occur in the United States. Most of
