O. rastratus sp. n. (Plate A [Plate XX.], fig. 5). 
Length about 450 fi. 
This belongs to the group of which alatus is the type, 
but the pteromorphae fall short of the middle of the cephalo- 
thorax. General colour dark vinous brown, paler near the 
fore margin of the dorsum ; very smooth and glossy. 
Cephalothorax wide at the base. Lamellae low ridges, 
doubly curved, converging rapidly, nearly parallel to the 
sides of the cephalothorax. Lamellar setae serrate, just 
reaching the tip of the rostrum, convergent and nearly 
horizontal. Pseudostigmatic organs long, slender, with long 
fusiform heads. Slightly leaning backwards. Inter- 
lamellar setae nearly upright, serrate. 
Outline of dorsum circular. Pteromorphae projecting 
forward about a third of the length of the cephalothorax, 
striate with divergent lines which reach well up the shoulder. 
Legs normal, tarsal claws 3. 
Among moss and dead hawthorn leaves, Ninebanks. 
O. dominae sp. n. (Plate B [Plate XX.], fig. 1). 
Length about 520 /z. 
Red brown. Dorsum closely and finely punctured but 
glossy ; broad oval, bordered in front. Pteromorphae 
transparent. No dorsal hairs. 
Cephalothorax broadly triangular ; rostrum rather 
pointed. Lamellae mere ridges, short, very convergent. 
Lamellar hair long and very strong, almost spinous. Inter- 
lamellar setae also unusually stout, upright below, then 
reflexed. Pseudostigmatic organ erect, rather long, with 
a roughened fusiform head. First tectopedia reaching far 
forward, bristle-tipped. 
Tarsal claws 3. 
Originally sent to me by Mr. Bagnall from the coast near 
Whitley Bay, and later from the Derwent Valley (Durham). 
Since found in West Allendale on the piers of a bridge in 
tufts of Bryum. 
O. lucifer sp. n. (Plate A, fig. 7). 
Length about 330 /z. 
Colour a rosy yellow, legs yellow brown. Pteromorphae 
yellow, transparent. 
Abdomen a broad oval ; dorsum rather flat, without any 
hairs ; median projection of fore margin straight.
