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.

- vernalis, L. Land's End ; St.

 Trox sabulosus, L.

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.
