COLEOPTERA IN HEREFOEDSHIKE (IV). 



KY J. R. LE B. TOMLIN, M.A., F.E.S. 



My last series of notes oil collectiii<^- in this county appeared in the 

 " Ent. Mo. Mag-.," 1910, pp. 1 39-141 . The list that follows is the result 

 of several forays at diffei-ent times of year, and a fair amount of fresh 

 ground has been explored. I published a note in the " Entom. Record," 

 1910, p. 189, recording 13 species of myrniecophilous beetles from nests 

 of Formica rufa at Syinond's Yat. These were all new to Herefordshire. 

 The matter of political boundaries in the Symond's Yat neighbourhood 

 is rather complicated, and, without an ordnance map, bewildering. 

 You get out of the train in Gloucestershire, but cross into Herefordshire 

 to post a letter some 50 yards away ; the opposite bank of the river, 

 with the big limestone masses of the Grreat and Little Dowards (almost 

 the only limestone in Herefordshire) , is part of the latter county for 

 some two miles in the Monmouth direction, whereas the left bank 

 belongs to Gloucester from the station do^Tiwards. 



The following species are all new to the county list. I would call 

 special attention to the occurrence of Bembidium adustum, Schaum. 

 The loeaUties Cusop and Olchon are used to designate Ijriefly two small 

 valleys running up into the Black Mountains. The species recorded as 

 from River Monnow, were all collected on the bank of that river 

 between Pontrilas and a point about a mile from Pandy. The total 

 number of species now on record is well over 1,300. I am much 

 indebted to Mr. Elliman for looking over a number of Homalota.
