ZOOLOGY. 
Rhantus exoletus in County Mas^o. 
As the above Water-beetle is not included in Mr. Balfour-Browne's 
list of aquatic coleoptera from Clare Island and adjacent mainland — 
"Clare Island Survey" {Proc. R.I. A., vol. xxxi.) — the capture of a 
specimen in a small lake near Westport, which is included in the district, 
in August, 191 1, may be worth recording. I am indebted to Mr. Halbert, 
of the Dublin Museum, for kindh- naming the insect for me.

Notes on Irish Beetles. 
In a recent paper {Entom. Month. Mag. (2), xxi., p. 62), J. N. Halbert 
records many of the rarer beetles occurring at Shane's Castle, on the north- 
eastern shore of Lough Neagh. Some of the more interesting species 
such as Cryptophagus himaculatits and others, have already been noted 
in the Irish Naturalist (xix., p. yi). Amongst the species not mentioned 
in this latter reference is the black variety of Paramecosoma melano- 
cephalum, Herbst., which replaces the type form in Ireland ; a varietal 
name (var. infuscatiim) is proposed for this insect. A large brown form 
of the same species, with stronger puncturation, which would seem to be 
referable to the variety univeste, Reitter, also occurred in the same locality. 
G. C. Champion records {Entom. Month. Mag, (2), xxi., p. 70), the 
capture by F. Bullock of an example of Grammoptera ruficornis, F., var. 
paUipes, Steph., at Killarney. We are glad to hear that Mr. Bullock, 
who collected with great success in the Dublin district some years ago, 
is continuing his entomological work in the south-west of Ireland, where 
there has always been an absence of resident collectors of coleoptera. 
P. Cameron records {Entom. Month. Mag. (2) xxi., p. 280), an example 
of a rare rove -beetle, Athcta {Homolota) picipennis Mann., fromi Rathmullan, 
County Donegal. It was taken on the wing on July 4th, 1909. Apparently 
this is the second recorded occurrence of the species in these islands ; 
and it confirms Dr. Joy's previous record of Hornalota picipennis as a 
British insect. 
In the Entom Month. Mag. (2), xxii., p. 153, F. Balfour -Browne describes 
a new species of Haliplus which he calls H. nontax. It belongs to the 
difficult " riificollis " group of the genus, and occurs in canals, lakes, 
and large drains of clear water, in England, Scotland, and Ireland. 
Some useful notes on the nomenclature and habits of the British and 
Irish species of Longitarsus are supplied by Messrs. Tomlin and Sharp 
in a recent paper {Entom. Month. Mag. (2) xxii., p. 241). We may point 
out that the insect usually recorded from Ireland as Longitarsus ater, F.,
