Indeed the present'- variety seems to be intermediate between the 

 two mentioned species.

Oribata verticillipes (Nie.) (non Michael). 



Michael in « Das Tierreich , Oribatidae » p. 59 describes under 

 the name Damaeus verticillipes Nic. his own species. He is 

 wrong in doing so. The species of Nicolet is quite another one, 

 at least two times longer, broader, higher. Nicolet has figured 

 his species pretty well, only the legs are drawn too slender, and 

 the hairs on the legs too fine , both are thicker. The two species 

 are immediately distinguished by the following characters : 



Orlhata verticillipes (Nic.) is about 0,7 to 0,75 mm. in length. 

 Its pseudostigmatic organs are rod-like, straight, long. Its inter- 

 lamellar hairs are rod-like, longer than the pseudostigmatic organs , 

 they stand upward and somewhat curved backward. Its nympha 

 = Damaeus torvus C. L. Kocii , C. M. A. fase. 3, f. 14 and Tijd- 

 schrift voor Entomologie v. 39, tab. 10, f. 20, has enormous long 

 curved hairs on its abdomen. Whilst : 



Oribata michaeli Oudms. 



whicli name I give to Orilata verticillipes (Michael) (non Nie), 

 is about 0,360 mm. long; its pseudostigmatic organs are vei'y 

 long, setiform, with undulated distal end; its inlerlamellar hairs 

 are setiform, curved, much shorter than the pseudostigmatic organs. 

 Its nympha, probably = Noihrtis pollinosus G. L. Koch, CM. A. 

 fase. 29, nr. 12, has short, curled hairs on its abdomen.
