Bryobia humekalis, sp. nov. (PI. 21. figs. 25 a-c.) 
A small species, length about 330 /u,, breadth 270 /u.. Colour red. Body 
strongly and suddenly narrowed at both extremities^ shoulders very promi- 
nent. Frontal tubercles oi: ce|)halothorax comparatively short, c^irrying 
strongly-curved spatulate hairs (PL 21. fig. 25 6). End margin of abdomen 
with five pairs of similar hairs, the three inner pairs being very conspicuous; 
there is also a double row of three or four hairs near the middle line of the 
body and a pair at the shoulders. Palps very short, appendage of fourth 
segment large and stout, terminal claw strongly curved. Legs shorter and 
stouter than in B. prcetiosa and of more uniform breadth, the second seg- 
ment of the first pair being noticeably shorter ; the two end segments are 
of nearly equal length (PI. 21. fig. 25 <•)■ 
Apart from the difference in the legs, this species may be known from 
B. prcetiosa by the smaller size, the shorter frontal tubercles, the more 
stronoly narrowed body, the more prominent shoulders, and the longer body 
hairs. 
Localities. Found at Clontarf, near Dublin, in March 1907. The corre- 
spondent who sent me the specimens had his attention drawn to them by 
the patches of red colour on a garden wall caused by the presence of large 
numbers of this mite. North shore of Lough Neagh, in wet moss, August 
1922. Mr. Evans has found the species amongst moss collected near 
Edinburgh. 
Rhaphignathus patrius, Berl., var. tkuncatus, nov. (PL 22. figs. 26a-c.) 
A robust form evidently allied to R. patrius, Berl., and in ail probability 
a variety of this species. Differs notably in the narrower body ; of the type 
Dr. Berlese remarks : " fere seque longium ac latum humeratum"; the end 
margin is very distinctly truncated, and the areolations of the epidermis are 
fewer and larger. 
Length 420 /a, breadth 320 fi. Colour blood-red, with a central dark area in 
front and four dark blotches on each side of the body, much as in Berlese's 
drawing of B. clavatus (1, Fasc. xxii. n. 2). Cephalothorax bluntly pointed 
in front, the sides slightly sinuate behind this, and they merge evenly with 
the shoulders of the abdomen ; the margins of the latter narrow gradually to 
the truncated end margin, at each angle of which there is a hair somewhat 
longer than the body hairs. Tliere are nine pairs of hairs in all, including 
the frontal hairs, and the latter are the only ones which have a trace of 
secondary' hairs. Epidermis very coarsely punctured, and there are paired 
circular pits close to the shoulders ; the end of the dorsum is slightly 
depressed. On the ventral side the anal plate and the areas surrounding the 
epimera are strongly areoLited, and on the hinder margins of the formei- are 
two spine-like hairs. Palps (Pi. 22. fig. 26 b) very stout ; second segment with 
a long, bent hair, which may, apparently^ be either simple or trifid at the 
extremity ; third segment with a similar dorsal hair ; length of palp about
