Johnson and Halbert — A List of the Beetles of Ireland. 657 



Up to the present time X crilripennis has only been found in the 

 counties of Donegal and Derry. The Portrush record ('97 J. 1) is 

 to be deleted, although the insect is exceedingly likely to be found 

 in that locality, and indeed in other places in the north and west. 

 Mr. C. W. Buckle has taken it in abundance at Magilligan, on the 

 fringe of the sandhills, and in a similar situation near the golf-links 

 at Buncrana. X. crilripennis is recorded from France and Italy, and, 

 according to Eeitter, a species {X. fortepunctatus) from the Caucasus 

 is synonymous with it. It seems remarkable that the Irish records of 

 X. crilripennis should be from the extreme north, in view of its very 

 marked southern range on the Continent, but similar cases are known, 

 that of Hydroporus obsoletus, Aube, may be mentioned. We have not 

 seen any examples of the insect recorded as X. distans from many 

 northern localities in Great Britain, but it is likely that some of the 

 specimens at least may be referable to the present species. 



X. linearis, 01.

Common. 



X. longiventris, Heer. 



This species is often treated as a mere variety of the foregoing. 

 If examined under a high power it may be recognised by the fact that 

 the siuface of the thorax is quite smooth between the punctures, and 

 therefore more shining — while in X. linearis it is marked with exceed- 

 ingly fine lines running in a transverse direction. In the Irish speci- 

 mens of X. longiventris the thorax has fewer and coarser punctures,, 

 both in the dorsal series and on the sides ; the elytra are slightly 

 longer on an average, and much more finely punctured. In Ireland 

 the preceding species is apparently the prevalent form — but X. longi- 

 ventris has been found on the following localities : — Donegal (Bnickless, 

 J.), Dublin (^^orth BuU, Ht.), AYexford (Enniscorthy, Ht.), Kerry 

 (Dingle, Valentia, and Kenmare, Ht.). 



Leptaeinus parumpunctatus, GyU. 



Leenstee. 

 DubUn ('54 Hn.). 

 There are Irish examples in the Haliday collection. 



L. batychrus, Gyll. 



Leenstee. 

 Dublin ('54 Hn. ; Howth and Dundrum, Ht.).
