His mite materiais, originating DOm Variolis collecting localities,are in the collection of the Mugeum ; they were unWorked Out for Some decades, for Iack of a specialist On the staff.

hut never publighed their respective figures. I also found a very interestingori balid which, having described ii as a Hungarian species in 1943, I have now to reconsider as heing actualty an Eastern African one, having listed itin advertently as a IIungarian Oribatid. In the followings, Ι present the descriptions and figures of these tenspecies. For the salie of brevity, Ι designate the collecting localities merelyas Κihostia and Αrustia. Concerning the Order of sequence of the species, Ι followthe book of BARER & WΗΛΗΤΟΝ : An Introduction to Acarology I9503. Though the systematios as given in this Work had, in the meantime, sufferedseverat modifications , I found it advis able, in a paper of a purely descriptive Character, to adhere to the system of this handbook, is only for practica1

Ι have the Ι1onour to dedicate this species to Pros. L. VARGA, the Nestor of Hungarian soli Zoologisis, of egregarious meriis in the biological research on the solis of the Sahara.
