Land's End district (Baily) PARMIDAE (continued} Parnus prolifericornis, F. auriculatus, Panz. HETEROCERIDAE Heterocerus marginatus, F. Sioan- pool obsoletus, Curt. Padstow LUCANIDAE Lucanus cervus, L. The stag beetle. Apparently only a casual in the south-east of the county, as two single specimens from Mount Edg- cumbe and one reported by Keys from Saltash are the only records Dorcus parallelopipedus, L. Sinodendron cylindricum, L. SCARABAEIDAE Onthophagus ovatus, L. coenobita, Herbst vacca, L. fracticornis, Payk. On sand- hills near Perranporth ; Pen- zance district ; St. Martin's, Stilly (Champion) nuchicornis, L. S. Aphodius erraticus, L. S. subterraneus, L. fossor, L. S. haemorrhoidalis, L. foetens, F. About Land's End in the first week of October ; St. Mary's, Stilly (Champion) fimetarius, L. S. scybalarius, F. S. - ater, De G. - constans, Duft. granarius, L. nitidulus, F. Abundant, Whit- sand Bay east ; common, S/. Mary'i, Stilly sturmi, Harold. A single ex- ample of this species new to the British Isles was taken by Keys at Whltsand Bay in 1902. It was identified by Herr Bourkill and confirm- ed by Herr Reitter (Ent. Record, 1903, p. 92) sordidus, F. rufescens, F. S. porcus, F. scrofa, F. Recorded by Steph- ens from Pentire Pt., Padstow, but has not been captured in the county since his time tristis, Panz. pusillus, Herbst. Land's End merdarius, F. S. inquinatus, F. tessulatus, Payk. sticticus, Panz. punctato-sulcatus, Stm. S. prodromus, Brahm 196 SCARABAEIDAE (continued} Aphodius contaminatus, Herbst obliteratus, Panz. Penzance district (Marquand) luridus, F. Rome (Keys) rufipes, L. depressus, Kug. Heptaulacus sus, Herbst. Altamun Oxyomus porcatus, F. Psammobius caesus, Panz. Two or three were found on Tresco, Stilly, by C. W. Dale in October, 1890. A very unexpected locality sulcicollis, 111. Padstoui porcicollis, 111. A few speci- mens of this rare and re- markably local species were found by J. J. Walker at Whltsand Bay, and it has been frequently taken there of late years by Keys, who writes ' I find it in sandy places under stones on the cliffs and at roots. It is so ex- tremely sluggish in its move- ments that it hardly seems likely to become distributed. Possibly the beetle is a root feeder, as I once took twenty several inches down in the soil' Aegialia arenaria, F. S. Geotrupes typhoeus, L. S. spiniger, Marsh. S. stercorarius, L. mutator, Marsh. S. sylvaticus, Panz. S. - vernalis, L. Land's End ; St. Mary's, Stilly Trox sabulosus, L. scaber, L. One between Per- ranporth and Netvjuay Hoplia philanthus Fuss. CtnmaB (Fowler) Serica brunnea, L. S. Rhizotrogus solstitialis, I* S. Though the larvae of this species are not usually accused of doing much injury to farm crops in England they have from time to time done a considerable >mount of local damage in Cornwall. In 1 890 and 1891 they did a great deal of harm to the crops of dredge corn about Perranporth, and in 1901 did conspicuous mischief in oats and dredge corn about Truro. They were noticed in abundance in fields about Bodmin some years ago, but as almost all injury to farm crops from soil-larvae is attri- buted to wireworm it is at present difficult to estimate the total amount of damage done by any particular species.
