WITH DESCRIPTIONS OF NEW SPECIES. 377 
Locality. Several females were found under branches and pieces of Vvood 
lying on fhe river bank at Glendalough in April. 
Tkachytes pi, Berl., var. paupbriok, Berl. 
1915. Berlese, 9, p. 135. 
Differs from the typical form (7) in its paler colour, smaller size, and in 
the form of the epigynum which is more elongate and punctured. The 
length of the Irish specimen 'is 484 /t, breadth 286 /i. Evidently closely 
allied to T. minima, Triig. (44, p. 448), but in the present form the anterior 
part of the body is much m.ore elongate and the shoulders are less marked. 
Locality. A single female found under decayed wood at Poulanass, 
Glendalough, in April. 
Ueoseius acdminatus, C. L. Koch. 
Locality. A few specimens were found in company with numbers of Vropoda 
ohscura, C. L. Koch, in decaying potatoes, Rocky Valley, Co. Wicklow, 
September 1921. The species has been recorded from Italy, Switzerland, 
Germany, and Great Britain. Hull queries the " Cilliba vegetans " of (25) 
as the present species, but the nymph recorded as such can have no rela- 
tionship with Uroseius. The adult form of the " Cilliba vegetans " of authors 
has not been made known. 
DiNYCHUs (Peodinychus) caeinatus, Berl. 
1903. Berlese, 3, p. 247. 
This species is briefly described in the above I'eference, and it is not 
figured ; Dr. Berlese, who has kindly verified the identification, refers the 
species (mi lit.') to his subgenus Prodinychus. The size is rather small for' 
this genus (length of Irish specimens 622 yu,, breadth 333 /a) ; shape of main 
body a regular oval, anterior part rather acutely pointed. In the middle 
line of the body there are two carinse, and between these and the slightly 
raised lateral margins. the dorsum is concave. 
Locality. I have found this distinct species in two localities in Co. Dublin, 
once in decayed bulbs in January, and under bark of old moss-grown tree 
trunks at Lucan in April. 
Phaulocylliba virgata [Hull). 
1918. Cillibano virgata, Hull, 25, p. 44. 
The original description is as follows : — " Sub-circular, smooth, claret brown. 
Dorsal shield divided by a very shallow median furrow forked behind the 
middle and curved backwards on each side to the margin, leaving a transverse 
part behind which bears a pair of clavo-pectinate setse. Two similar setae 
stand in a line with these on the lateral margin. Epigyne oval, rounded at 
both ends, apiculate in front. Ventral shield reticulate."
