1896.] Hai^bert. — Clonbrock Expcditio7i, Coleopfcra. 233 



The Rhyiichophora or weevils usually come last in beetle 

 lists ; they are without exception vegetable-feeders, the greater 

 number being extremel}^ conservative in keeping to their 

 respective food-plants. The first weevil deserving of notice 

 in the Clonbrock list is Rhyiichites jjiinutus, Herbst., found on 

 two occasions by sweeping near willows. This species was 

 added to the Irish list last year by Mr. J. J. Walker, who found 

 it at Queenstown.^ Apioii Gyllcnhali, Kirby, and ^. marchicuvi, 

 Herbst., were the best species of that extensive genus ; 

 although I had previously collected the latter, generally in 

 marshy places, I have never succeeded in taking more than 

 one or two specimens on any occasion. Sweeping large 

 patches oi Eqiiisctum in drains produced Grypidius cquheti, F., 

 a queer beetle looking not unlike a seed-head of that plant, to 

 which it is exclusively attached. One of the most satisfactory 

 discoveries made on this excursion was the occurrence of 

 Erirrhinus csthiops, F. I found a single specimen of this rare 

 weevil under a stone, on the banks of the Suck. Up to the 

 present it had been found only by the Rev. W. F. Johnson 

 in Co. Armagh"^. According to Canon Fowler, the species 

 is of extreme rarity in England, but it occurs in several Scotch 

 localities ; it will probably be found commonly enough when 

 the midlands are better v/orked.^ Amongst other captures 

 I may mention the following : — Polydrusus cejvinus, L,., 

 Orchestes rusci, Herbst., and O. ilicis, F., Doiytovius maculattis, 

 Marsh., abundant ; D. pedoralis, Gyll., Cceliodes 7'iibicunduSy 

 Herbst., and Poophagus sisymbrii, F. 



The beetles occurring on the banks of the Suck afforded 

 a rather typical example of the gathering of northern and 

 southern forms, that adds such interest to collecting in Ire- 

 land. In company with Erh^himis cEthiopSy which has a 

 decidedly northern range, I found a ground-beetle {Trechus 

 discus) having for its habitat the river-valleys of the midland 

 English counties, while with both might be found a rove- 

 beetle {Philo7ith2cs qui squiliar ills), a species that has apparently 

 Cambridgeshire for its northern limit in Britain. Examples 

 of this mingling may be found in almost any part of Ireland, 

 but they are undoubtedly most characteristic of the west.

 Tempo, Enniskillen, by Mr. C. Langham.
