curved bars; one of them does not start from the pseudostigma, 

 but from a Httle distance in front of it, then bending inward and 

 forward ; tlie other forming a bow with its convexity outward , 

 just as in the two above mentioned species, with this difference, 

 however, that they reach in the present species nearly the tip of 

 the rostrum. No lamellar hair nor interlamellar hair present. 

 Between the pseudostigmata, or, as Michael expresses himself, 

 between the lamellae, there are two short bars, springing from 

 the anterior margin of the abdomen; these bars are not joined by 

 a transverse bar, and are directed obliquely outward. 



The abdomen is smooth, finely punctured, and bears as far as 

 I could observe , two transversal rows of four hairs each , and 

 eight on, or quite near the posterior margin. All the hairs are 

 exceedingly fine. 



The legs are of the common type; the femora and tibia davate, 

 the tarsi pyriform, the claws monodactyle. 



I propose to change the «key» on page 44 of «Das Tierreich, 

 Oribatidae » as follows : 



Rost, truncated , three-pointed — 23a. » 



Rost, not truncated — 24. 

 I Bars joined anteriorly by a transverse bar . E. trigonus.

E^emaeus longilamellatus (Michael) 

 var. neerlandica Oudms. 



This variety (fig. 4) differs from its type by having no long 

 lamellae , but short ones. The long lamellae viz. are broken up 

 into three pieces, and these three pieces together don't reach 

 farther than the middle of the céphalothorax. Moreover outwaixl of 

 the concavity of the lamellae there are tliree chitinous eminences 

 placed in a triangle. The céphalothorax is broader than in the 

 type, and posterior to the pseudostigmata there are two T-shaped 

 chitinous bars , running from the anterior margin of the abdomen 

 toward the pseudostigma, as in Eremaeus splendens (G. L. Koch).
