ADDITIONx\L RECORDS OF IRISH COLEOPTKRA. 



BY REV. W. F, JOHNSON; M.A., F.E.S. 



I find a number of species in my collection which I have 

 neglected to record, and I propose now to remedy that defect. 

 I am much inde1)ted to Mr. F. Balfour Browne, F.Z.S., for 

 kind help with some of the water-beetles ; he went through 

 all my specimens and succeeded in detecting several species 

 which I had overlooked. 

 Haliplus flavicollis, Sturm. — Poyntzpass, in the canal and adjacent 



drains. 

 Hydroporus septentrionalis, Gyll. — Dean's River, Armagh. 

 H, umbrosus, Gyll. — Canal near Scarva, but in Co. Armagh. 

 H. vittula, Er.— Poyntzpass. 

 H, incog^nitus, Sharp. — Ardara, Co. Donegal. 

 H. celatus, Clark. — Poyntzpass. This species has been regarded as a 



sj'nonyra for H. longtdus, Muls, but I am informed by Mr. E. A. 



Newbery that Seidlitz, in his work on the Dytiscidas, separates 



ct'latus and longiilus as follows : — 

 A. Klytra with diffuse punctuation, without pubescence, strongly 



shining, black ; thorax more finely punctuated on middle of disc, 



1. 3 — 3.5 m.m. In the South of France and in Spain (Pyrenees, 



Pandellf). to/ii^itliis, Muls. 



A. A. Elytra densely punctured, finely pubescent, little shining; 



thorax scarcely more finely punctured on disc than margins, black ; 



legs and antennae pale red ; sometimes the elytra are reddish ; 1. 



3 m.m. In England and France. celatus, Clark. 



In the last European catalogue (1906), longiihis Rey. is given as a 



synonym oi celatus Clark. It seems doubtful that loiigiilus of Mulsant 



is a British insect. Celatus Clark, however, is, Mr. Newbery tells 



me, in his experience widely distributed in England and Wales
