view, and the results of our investiga- 

 tions entirely confirm the latter opinion. 

 It is very prohable that its distribution 

 may eventually be traced all over the 

 country in hot-houses, as it is often to 

 be found in large numbers in such places. 

 There are only a few records of its 

 occurrence intheS.E. of England; but 

 it has also been taken in Scotland ; 

 while in other parts of the world it is, 

 as M. Budde-Lund says, a "cosmopolitan 

 species."

This species is very common in Kerry 

 and Cork, from which counties we have 

 respectively records from 10 and 7 

 localities. It occurs also in several of 

 the maritime counties on the west coast 

 and in the south-eastern corner, and

seems to be commonest in mountainous 

 districts. It has been taken in England 

 in Devonshire only ; while on the 

 Continent it is recorded from the south 

 of France and Spain only.

A few specimens of this very rare 

 "Woodlouse were taken on the southern 

 cliffs of the Hill of Howth, Co. Duhlin, 

 by Mr. J. N. Halbert in 1909, and were 

 recorded in the Irish Waturnlist, vol. 

 six, p. 92, by Dr. Scharff. A further 

 examination of the locality shows that 

 it exists there in some numbers, living 

 under tufts of grass and Silene maritima 

 on the face of the cliff. It has not yet 

 been taken in Great Ej-itain, nor indeed 

 anywhere nearer than the south of 

 France. The only other localities for 

 which M. Eudde-Lund i-ecords it are 

 Corsica and one or two spots in northern 

 Africa. It is another example of those 

 southern or "Lusitanian" species, so 

 many of which are found in Ireland, 

 and which add so much interest to the 

 study of the fauna and flora of this 

 country, 



We give a figure (Plate VIII., ?i\x 3) 

 of this interesting species, as none has 

 liitherto beeu published in any English 

 paper.
