Native name Mhuwe."-A. W. 3. O n a new Genus and Species of Acaridea. By Bev. O. P I C K A R D C A M B R I D G E , M.A., F.B.S., &c. [Received October 26, 1897.] (Plate LV.) The singular Acarid of the family Trombidiidae now described was kindly sent to me by the Bev. A. E. Eaton, who found it, along with another, running on sandy ground amongst tamarisk bordering the river-bed near Biskra in Algeria. Mr. Eaton writes that " in running it elevates the hindermost legs, which being quickly agitated, the tufts of hairs on the metatarsi look like a pair of minute Diptera dancing attendance on the mite." Gen. nov. EATONIA (nom. propr.). Form obtuse-oval, tolerably and uniformly convex above. Caput and thorax coalescing with scarcely a trace of junction. A pointed nasiform process issues from near the middle of the anterior margin, and from this process to the hinder extremity of the caput is a deepish longitudinal furrow or indentation bisecting the caput. Eues 4, in two groups of two eyes each, seated on either side of the caput on geminated tubercles. Leas slender, 1, 2, 3 short, 4 long. Two on each side issue - 62* |
