Order SCORPIONIDA. 

 Family Centrurid^. 

 Centrurus carolinianus Beauvois. 



This seems to be the only species in the state. It is common under 

 loose stones in limestone regions, and is less frequently met with 

 under sandstone or loose bark in other localities. Specimens were 

 taken at various times of the year in the following counties : Doug- 

 las, Pottawatomie, Riley, Ottawa, Russell, Smith, Clark, Barber, 

 and Morton. 



Order PSEUDOSCORPIONIDA. 

 Family Cheliferid^. 

 Chelifer cancroides Linnseus. 



This species is found in almost any part of the United States. We 

 have, in the college collection, specimens from Lawrence, Manhat- 

 tan, and Sun. Most of them were taken under bark. 



Order SOLPUGIDA. 

 Family Solpugid^. 

 Eremobates pallipes Say. 



These curious arachnids are not uncommon in the western and south- 

 western parts of the state. They are nocturnal in habit, and during 

 the day are usually found under stones or cattle chips. Specimens 

 have been secured in Wallace, Seward, Clark and Morton counties. 

 But one Kansas species is known. 



Order PHALANGIDA. 



Family Phalangid^. 

 Liobunum vittatum Say. 



Phalangium vittatum Say. Am. Ent., Lee. ed., vol. II, p. 13. 



This is the common "daddy-long-legs" found in most parts of the 

 United States. It includes Say's L. dorsatum, the more northerly 

 type of the species. Abundant in the central and eastern portions 

 of the state, but only occasionally met with in western and south- 

 western Kansas. Specimens from Delphos, Manhattan, and Law- 

 rence, August to October.
