242 THE entomologist's kecord. 



'■'Diglotta mersa, Cilenus lateralis, and ■' Blediiis longulus were taken 

 under stones on mud below high-water mark, Byrrhus fasciatus on 

 walls, Aniara patricia under stones on the hills at the back of the town, 

 and, in a swamp near the railway, Tachyusa atra, Philonthus micans, 

 Stenus ater, Anchomenus vidnus, Homalota graminicola, Ijathrohiuni 

 quadratum, and Demetrius atricapillus were taken, and Hoplia philan- 

 thus was swept. At Llanbedr, the best things were Telephorus fuscns 

 and ''Larintis carlinae. The weather was cold and wet during the 

 whole visit, which no doubt somewhat spoiled the collecting. On the 

 26th a rush back to London was made for social duties, but the 29th 

 saw me again on the road to north Wales, this time to meet my col- 

 league, Professor Beare, and to go to Snowdon. June 30th saw us early 

 on foot from Llanberis, which we made our headquarters, to make the 

 ascent of Snowdon, and we first devoted ourselves to the capture of 

 Chrysomela cerealis, the object of the trip, of which we each took a 

 dozen specimens, and then turned our attention to other mountain 

 species. Search under stones produced Pterostichus aethiops, common, 

 P. vitrens, rare, Carahus arvensis, Nebria </yllenhali , Corymhites cnpreus 

 var. aerufiinosus, etc. Shaking moss at the top of SnoAvdon proved 

 the most productive means of obtaining beetles, and, in this way, we 

 took Anthophagus alpinns, Mycetoporus angularis, ''Oxypoda soror, 

 Geodrouricus glohulicollis, Byrrhus fasciatus, and Patrobus assimilis, all 

 not uncommon, and Acidnta crenata and -''Heterothops praevia were 

 taken sparingly. Oxytellus nitidulus and TrogopJiloeus corticinus were 

 wrung out of moss in a small waterfall. Homolota tibialis and H. 

 eremita, among other species, were common in the moss, and a few H. 

 alpestris were taken, Rhagonycha paludosa was swept in numbers off 

 rushes. The red form of Agahnsbipustulatus (var. soleri.') was common 

 in the loch. The species marked with an asterisk appear not to have 

 been recorded from north Wales before. — Horace Donisthorpe, 58,

H0M.\L0TA CUSPmATA, Er., AND ITS PREY, AnOURA MUSCORUBI, TeMPL. 



— The very distinct Homalota cuspid ata, Er., has fallen to me several 

 times this year beneath bark of oak and birch near Winlaton, and 

 that of beech in Gibside. In all cases it was found in association with 

 colonies of a peculiar apterous grub-like insect belonging to the 

 Collembola, and which I am now able to identify as Templeton's 

 Anoura (Achorutes) mnscorum, and, this evening, finding the Anourain 

 the first instance, further search revealed also the Homalota in question. 

 On three occasions I have watched H. cuspidata devouring J. muscoriun, 

 and, in the circumstances, I think there can be little doubt that it forms 

 the chief food of H. cuspidata. Lipura corticina, Bourlet, an allied 

 Podurid of sub-cortical habits also falls a prey to H. oispidata. 

 The species mentioned are all additions to the Northumberland and 

 Durham fauna. — Richard S. Bagnall, F.E.S., Winlaton-on-Tyne.
