The first group is characterized by a long, narrow rudiment of 

 a dorsal shield quite anteriorly, by the absense of a villous sub- 

 tarsal scale, and by its tarsi provided ventrally with 3 sinall hairy 

 hairs. It contains : 



1 (2) Glycyphagus domesticus (de Geer), 1778. 



2 (13) * ornatus Kramer, 1878. 



3 (24) » privatus Oudemans, 1903. 



The second one by the absense of a rudimental dorsal shield, 

 the absence of small hairy hairs ventrally of the tarsi, and the 

 presence of a villous subtarsal scale. It contains: 



1 (1) Glycyphagus cadaverum (Schrank), 1781, ex 1776. 



2 (7) » setosus (C. L. Koch), 1841. 



3 (21) » michaeli Oudemans, 1903, ex Michael, 1888. 



4 (25) » fustifer Oudemans, 1903. 



5 (26) » burchanensis Oudemans, 1903. 



With the most certainty we may presage that if Glyc. cubicula- 

 rius and troupeaui are found again, these species will proove to 

 belong either to the domesticus- group, or to the cadaverum-gr ou\). 



I have not denominated the smaller groups in the genus Gly- 

 cyphagus sensu stricto Oudemansi, but I think that we will soon 

 are in want of it.
