The value of the different genera and subgenera in which the old genus 

 Chelifer Geof. have been divided will be discussed later on (cf. pp. 130—134).

'1 Simon's genus Lophochenies is according to my opinion quite a natural one, luit its name must 

 necessarily be altered, because it includes Ch. cancroidcs L., which Is the type of the whole genus 

 Chelifer Geof. 



-) Daday (11. p. IGS) lays in the characteristic of Chernes Menge the stress on the clumsy palps 

 and divides it into two subgenera: Chernes Menge without ocular spots and Ectoceras Steck, with 

 ocular spots.
