middle to the pseudostigmata. The latter are circular and strongly chitinized. 
Sensory organs with a stout slightly curved stem and a large club-shaped 
extremity wliich is minutely spiculate. Abdomen elongate, pointed at both 
extremities, hairs very weak. Epimera well defined. Legs normal, mono- 
dactyle. Length 240 /a, breadth 110 /a. 
Locality. Found under dead wood at Poulanass, Glendalough, Co. Wicklow, 
in March. The typical form is widely distributed^ occurring in Italy and 
near Washington, D.iS.A. (40).

Heemanniella geanulata {Nicolet). 
1865. JSermannia granulata, Nicolet, 35, p. 469. 
In his well-known work on French Oribatids, Nicolet described and figured 
two species oF Nermannia, i. e., H. granulata and H. arrecta (which he believed 
were distinct), difl'ering from each other in the form of the cephalothorax. 
As far as I am aware the distinctness or otherwise of these species has not 
been settled. It seems likely, however, that Nicolet's specimens, which were 
found in the same localities, represent but a single species, and that the 
supposed differences in the form of the cephalothorax may be more apparent 
than real. There is a tendency among acarologists to record LI. granulata 
in preference to LI. arrecta, it is also the first mentioned of the two species 
in Nicolet's monograph, so I think it is better to refer the Irish specimens 
here until the question has been decided. 
Localities, Adults and nymphs were found in some numbers in a decayed 
birch log at Glendalougli in April, and it has also occurred in moss collected 
at Howth, Oo. Dublin, in Juiae. 
Tarsonemus laticbps, sp. nov. (PI. 21. figs. 21 a-c.) 
A species allied to 2\ culmicohis, which is recorded by Eeuter (41) as 
causing injury to meadow grasses in Finland. Differs in the form of the 
body, the broader capitulum, and in other details. 
Female. Form rather short and broad (length 195ya-210/i, breadth 110 yu.) ; 
in ovigerous females the body is more elongate, becoming long oval (leno-th 
215/^), the enclosed egg measuring about 115 yu.. Side margins sub-parallel, 
front margin truncated and half covering the head, end margin rounded. 
Division between the cephalothorax and abdomen and the one at the middle 
of the latter distinct, but the segments at end of the abdomen are ill-defined. 
Hair armature very short except for the usual long pair close to the sides of 
the ceplialothorax, and a shorter pair at the angles of the front margin. The 
sensory organs (PI. 21. fig. 21 a) arising from small circular stigmata, are large, 
they may be either globular, or leaf-like with pointed extremities, and both
