 INSECTS Rhyparochromus praetextatus, occurs at St. Ives, and the nearly related R. antennatus near Land's End. The cliffs near Boscastle, where it was found by the Rev. T. A. Marshall, appear to be the only known British habitat for Trapezonotus Ullrichi. Aphanus rolandri was found in July, 1901, under some blown hay near Liskeard, and A. lynceus has twice been taken at St. Ives. That elegant and beautiful insect, Beosus luscus, is widely spread, and though taken most frequently about Whitsand Bay East, occurs also at Boscastle, St. Ives, Gerrans Bay, and Land's End. The very rare Emblethis verbasci was obtained by Champion at St. Mary's, Tresco and Samson, Scilly. The first specimens of the extraordinary sub-marine hemipteron Aepophilus bonnairei, found in England, were obtained by F. Smith, near Polperro, in 1879. A second colony was discovered by E. D. Marquand in 1886 at Mousehole on the very border of the laminarian zone. The developed form of Velia current has been taken near Tintagel, and that of Nabis lativentris occurred near Marazion in 1901. The rare Lopus flavomarginatus was obtained by Marshall at Polperro, and L. sulcatus has been taken lately by Keys at Tregantle. Phytocoris reutert appeared in a small orchard near Newquay in 1900. Allodapus rufescens was found among the Isles of Scilly by Mason. Orthotylus nascatus occurs in the oak-lined coombes of the Kilkhampton district and also around Penzance. Plagiognathus saltitans has been taken sparingly all over the west of the county, and Macrocoleus tanacetus is not uncommon near Launceston.
