order have large, conspicuous pedipalps (Kt). They . are 

 nocturnal in habit and live under stones and in crevices during 

 the day. They inhabit the warm countries and feed chiefly on 

 insects. 



Order 6. Palpigradi (Fig. 324). One family and two genera 

 belong to this order. They are small (about i mm. long) and

widely distributed. Several species have been recorded from 

 Texas. 



Order 7. Solifugae. The SOLIFUG^E . (Fig. 325) are fair 

 sized, hairy arachnids living in warm parts of the globe. About 

 one hundred and seventy species are known. 



Order 8. Chernetidia (Pseudoscorpionida, Fig. 326.) - 

 These are brownish arachnids from one eighth to one fourth of 

 an inch in length. They possess comparatively large pedipalps 

 with which they capture their insect food. Large insects to 

 which they cling often carry them about a fact that probably 

 accounts for their wide distribution. There is only one family.
