III. The Circkct-likc Grass/toppers. These are wingless, 

 and resemble crickets in form. The most common members of 



this group belong to the genus 

 ^..^^ Ceuthophilus (Ceu-thoph'i-lus) 

 (Fig. 130). These insects are 

 found under stones and rub- 

 bish, especially in woods.

Very closely allied to them are 



the colorless and blind Cave-crickets, Hadcnceais (Had-e- 

 nce'cus), found in caves.
