162 (DR. A. C. OtlDEMANS). NEW LIST OF DUTCH ACARI, I. 



iDors. of Abd. slightly curved S. COrrugatus. 

 Dors, of Abd. will) arched centre and broad, 

 flat , peripheral band S. maculatus. 



In the « key » of Tegeocranus on page 33 of « Das Tierreich , 

 Oribatidae», we have only to cross the first three lines. 



Carabodes marginatus (Michael). 



My specimen has the pseudostigmatic organs not so curved and 

 not so sharply pointed as Michael describes and figures, and the 

 hairs on the abdomen and on its margin are somewhat feathered 

 distally. Yet I don't believe it a new species, but a simple variety. 



Liacarus lativentris (Nie). 



Nicolet's figure is quite exact. I have only one remark : the 

 pseudostigmatic organs end in a hair; this is in my specimen 

 shorter than in Nicolet's figure. 



Eremaeus ex ills Nie 



On the dorsum of the abdomen there are 10 marginal moon- 

 crater-shaped organs, as I described in Eremaeus schieiderl OuDyis, 

 and other species, arranged as follows: two stand near the anterior 

 corners and are large ^ each side one, and the eight others , smaller 

 in size, stand close to the posterior margin. Only one of my specimens 

 has distinct cusps , the other have no cusps and the pseudostig- 

 matic organs vary from short-clavate with rounded top to moderate- 

 long-clavate with distal point. 



Therefore the « key » on page 43 of « Das Tierreich , Oribatidae » 



is to be changed as follows :
