A LIST OF IRISH SPIDERS. 125 
with a subsoil of chalk, which here and there comes close to the 
top, when the plants peculiar to that formation show themselves, 
the traveller's joy (Clematis) being one of these. The country 
is undulating, and in places decidedly pretty, affording some nice 
sunny slopes, on which good collecting may be expected. 
Thave notenumerated alist of the Lepidoptera taken in the Pinner 
district for the simple reason that, so far as I can find, it has been 
little worked. I am told that some years ago the following 
butterflies were taken in the woods :—Apatura Tris, Thecla quercus, 
T. betule, five species of the genus Argynnis, several V anessid@, 
Limenitis Sibylla, Arge Galathea, &c. Amongst moths, where the 
wood spurge is common, Minoa euphorbiata is sometimes abundant. 
I saw myself, on a recent visit, amongst other species, Cidaria 
silaceata, which I should expect to find, on a favourable day, in some 
numbers, for the food of its larva (Epilobium), is common over 
the whole woods. I much wonder that so fine a district, which is 
so comparatively close to London, has been so little worked; but 
I hope before long to receive, for this magazine, from some of our 
readers a good account of work done there.

A CONTRIBUTION TOWARDS A LIST OF TRISH SPIDERS. 
By 'THomas WoRKMAN. 
From the time that Dr. Templeton, in the first quarter of the 
present century, collected and described several species of Irish 
spiders, the results of which are embodied in Mr. Blackwall’s 
well-known work, ‘The Spiders of Great Britain and Treland,’ 
there seems to have been no observer until the Rev. O. P. Cam- 
bridge, to whom I owe a deep debt of gratitude, asked me to 
collect for him in the spring of 1877. 
Working as steadily as circumstances would permit from that 
time until now, I have been able to add considerably to the 
number of known species. 
Mr. Blackwall enumerates forty-three species as found in 
Ireland; and Mr. Cambridge, in his work just published, ° The 
Spiders of Dorset,’ gives three more, so that, with the sixty-five
