Recent researches by C. J. With and other zoologists have proved 

 that the genus Chelifer will certainly in the future have to In- 

 divided into several new genera, based on the different shape of the 

 sexual apparatus of the males, and With has already formed several 

 groups from this point of view : the birmanicus group, the 

 cimicoides group, the subritbcr group, and the cancroidcs group. 

 I shall therefore try to bring the species of Chelifer, enumerated 

 above, into these different groups, as far as it is possible at present ; 

 in some cases this cannot yet with certainty be done. I place 

 beside the groups the names which may ultimately perhaps be used 

 as generic titles. The name Withius has been proposed by 

 H. W T allis Kew, ::: the other names have been used before as generic 

 or subgeneric names, but based on other characters.
