I got the latter I generally expect to meet with the former ; 

 ver}' probabl}' the ensuing season will bring a record of its 

 capture. 



In connection w^ith these Ccela^nbi, can no one turn up 

 Ccelainbus versicolor, Schall. {7^eiiailat2is, F.) ? This pretty little 

 water-beetle is recorded by Halida}^ from near Belfast ; there 

 is also a specimen in the Belfast Museum, which was taken by 

 Mr. Hyndman probably near Belfast, and in M'Nab's Dublin 

 list is the record " Canal, Dublin" ; since that time it has been 

 conspicuous by its absence. I may mention that a convenient 

 point of distinction between it and C. v.-lhieatus, its close ally, 

 lies in the prosternal process, which in C. versicolor is elevated, 

 and in C. v.-lijicahis is depressed {vide Sharp, " D3^tiscid8e," 

 Sci. T?'a7is. R.D.S., 18S2). 



Mr. Buckle' speaks of not observing Hydroponis Davisii, 

 Curt., or H. scplenirio7ialis, Gyll., coming to the surface of the 

 water for air ; the fact is, that it is very difficult to see these 

 small water-beetles coming to the surface except in clear 

 water where there are no weeds, for they come up and go 

 down again so quickly that the least bit of weed ]3revents their 

 being seen. 



Mycetoportis Tianus, Hr., was recorded b}^ me from Coolmore, 



Co. Donegal {E7it. Mo. Mag., 1896, p. 156), and CeuthorrhyiicJius 



viduatus, Gyll., from Armagh {E7ito. Mo. Mag., vol. 24, p. 195.) 



Phytosus baliicus, Kraatz., is an interesting capture 



especially in view of Mr. G. C. Champion's remarks concerning 



it and P. 7iigriventris, Chevr. (E7it. Mo. Mag., 2nd series, vol. 10, 



p. i). Mr. Champion gives '* Co. Meath" as an Irish locality, 



which, with Mr. Buckle's record, are the only notices of its 



occurrence in Ireland that I know of. It seems not improbable 



that further research may produce both species from these 



localities, and possibly from others. It appears to be entirely 



a sea-coast insect. Blcdius eri'atiais, Er., is a decidedly rare 



beetle. Canon Fowler gives only four localities for it {Bfit. 



Col., ii., p. 373), nor do I know of any record of its capture 



since, except my own from Coolmore fl. Nat., vol. iv., p. 97), 



which is the only other Irish recoid except Mr. Buckle's. 



It is very gratifying to know that he met with it in large 



numbers. At Coolmore there was a large colony among the 



sandhills quite away from ihe sea-beach proper.
