28 BRITISH ORTHOPTERA. 



Robertson a fine pair taken on 14 Sept. 1902, and on 19 Sept. 

 Miss Nellie Robertson sent me two males and three females, 

 taken on the shore at Pokesdown. On 6 Aug. 1903, in 

 company with Major Robertson's daughters, I made the 

 personal acquaintance of L. riparia &t Pokesdown and in 

 about 20 minutes we took between us 16 specimens. On 

 19 Aug. 1903 I found several between Pokesdown and 

 Southbourne. On 12 and 27 Aug. 1904 I again captured 

 specimens at Southbourne, as also on 1 Aug. 1907. On 

 10 Aug. 1908 I took three examples, one being a very large 

 male, near Branksome no doubt in Kemp-Welch's locality 

 and A. H. Hamm took one on 12 Aug. in the same year near 

 Boscombe. On 3 Aug. 1909 I took three specimens near 

 Southbourne, and on 10 Aug. 1910 J. J. F. X. King and 

 myself took one or two more at the same place. In 1912 

 four were obtained near Southbourne on 20 Aug., four on 

 26 Aug., and four more on 31 Aug. In the autumn of 1914 

 R. B. Good found a single female under stones at the foot 

 of the cliff near Southbourne. After a strict search in Aug. 

 1918, two small nymphs only could be found. So it seems 

 likely, as mentioned above, that, as Bournemouth extends, 

 these earwigs may become extinct in that district in the near 

 future, and at present we know of no other British locality. 

 The Rev. J. Gr. Wood in ' Insects at Home ' mentions one 

 without date taken on the beach at Folkestone, but this 

 appears to need corroboration. Burr says it has been taken 

 at Bonchurch, Isle of Wight. 1 * 



From Liverpool three casuals have been recorded by E. J. B. 

 Sopp : a male captured in an office in Castle Street, in Oct. 

 1893 ; a male (lacking the tooth in the callipers), captured in 

 S. John's Market in July 1903; and^a nymph from Williamson 

 Square, 1902.
