1905. ] BRITISH MITES OF THE FAMILY ORIBATID#. 567 
The appearance of the living mite strongly recalled Serrariws 
microcephalus, but its chelate mandibles remove it from that 
genus. It also bears some superficial resemblance to Votaspis 
biprlis. 
Gen. Noraspis Warren. 
NorasPIs MACULOSA, sp. nov. (Plate XX. fig. 1.) 
Adult. Length 520 p. Colour light brown. Surface spotted, 
the spots being in the epiostracum and easily rubbed off. Cephalo- 
thorax very long and pointed, nearly } the length of the abdomen. 
Lamelle, long ridges, arising near the pseudostigmata, converging 
at first, and then extending parallel for 2? the length of the 
rostrum. Pseudostigmatic organs long and slender, very coarsely 
pectinated on their anterior border. Claws monodactyle. Ab- 
domen long oval, somewhat truncated at each end. Legs long 
and slender, with globular joints. 
Nymph and larva unknown. 
Three specimens were taken in moss from Nine Wells, Cambridge, 
in May 1905. 
The nearest allies of this fine species are among the minute 
forms of which WV. splendens is the type. Like them, it has a 
peculiar habit of shaking its beaded legs asitruns. Its large size, 
spotted surface, and pectinate pseudostigmatic organs render its 
identification easy. 
NorasPIS SCULPTILIS, sp. nov. (Plate XX. fig. 2.) 
Adult. Length 330». This mite has a close general resemblance 
to WV. splendens, but, on careful examination, may easily be 
distinguished from that species by the peculiar design of the ridges 
on the vertex and notogaster. These are best understood from 
the figure, but may be described thus :— 
The lamelle arise from the pseudostigmata, converge sharply, 
and then continue forward and parallel. Atthe extreme point of 
convergence there is a faint translamella, and from its extremities 
ridges proceed backwards. On the notogaster there is a well- 
marked transverse ridge close to its anterior border; the ends of 
this ridge curve abruptly backwards, approach slightly, and then 
separate again. 
Pseudostigmatic organs long, rough and hairy. 
Nymph and larva unknown. 
Ten or twelve specimens were found in wet Sphagnum sent by 
Miss Heath, of Crayford, from the Devil’s Punchbowl, Hindhead, 
in June 1905. 
This species seems to be allied to Hremaeus novus Oudemans. 
Subfam. NotHRINz. 
Gen. Notrurus C. L. Koch. 
NovHRUS CRINITUS, sp. nov. (Plate XX. fig. 3.) 
Length 900 ». Colour dark brown. Integument more fully 
chitinised than is usual in this genus.
