216 British Oribatidce : Xotcs on New and Critical Species. 
The pseudostigmatic organs arc rod-like, evenly but 
very slightly enlarged towards the extremity which is blunt 
and rounded. 
A few specimens only were sent to me by Mr. R. S. 
Bagnall from Holywell Dene, near the Northumbrian coast. 
PELOPTULUS Berlese. 
A genus (type phceonotns) established for the section of 
Pelops in which the quadrate median prodorsal projection 
is lacking and the interlamellar set as are of the ordinary 
Oribatine type. 
P. montaxus, sp. n. (Plate C, fig. 3). 
Length about 530 /x. 
Cephalothorax similar to that of phceonotns, but the 
lamellae are tridentate on the fore margin. The lamellar 
setae are short, stout and divergent, crossed by similar (but 
longer) convergent setae of the first tectopedia. 
The pteromorphae also resemble those of phceonotns, 
but they are visibly connected in front of the dorsum by a 
narrow extension, as in Pelops, but of course without the 
quadrate projection in the middle. 
Dorsum of the abdomen coated with dark brown secretion 
except a pear-shaped ‘ clear spot ’. It bears four rows 
(3.2 — 2.3) of fine hairs, and one pair of convergent thickened 
hairs on the posterior margin. 
Ninebanks, West Allendale, in sphagnum ; at 1,200 feet. 
Also at Holywell Dene (sub-maritime) in moss. Plate C, fig. 
13, represents a Peloptine nymph which is most probably 
of this species. 
ORIBATES Latr. (emend. Koch). 
O. sp., nymph. (Plate C, fig. 14). 
This is a nymph which I have twice taken in West Allen- 
dale — once in sphagnum, once in ground moss — but have not 
succeeded in rearing. It seems to be of the O. sphagni type, 
but is twice as as large. There are two spines on each side 
of the middle line of the dorsum— not a median row of two. 
as shown in the figure. For reference, this nymph may bear 
the provisional name of 0 . invitus. 
O. stag x at 1 Lis, sp. n. (Plate A [Plate XX.], figs. 8, 9, 11). 
Length about 720 /x. 
Lamellae upright behind, oblique and concave in front : 
terminal seta springing from an angular notch just below 
the acute cusp, short and serrate. Translamella nearly 
horizontal. Interlamellar setae upright below, slightly 
curving forward above, serrate. Pseudostigmatic setae long, 
slender, recurved, flattened distally, and widening evenly 
to the truncate extremity. Tectopedia large, the second 
unusually prominent.
