He was born in
Penzance, Cornwall and trained at
St. Bartholomew's Hospital, London. Appointed surgeon in the
Navy he served on Australian,
West Indian and
Mediterranean stations. He married a Miss Mary Glasson of
Cornwall and settled at
Trewhiddle near
St Austell where his wife's property produced
china clay. Widowed in 1851 he settled in London devoting himself to
natural history and
entomology in particular. The results of collecting trips to Europe, North Africa and the
Lower Amazons were poor and Pascoe worked mainly on insects collected by others. His entomological papers listed and described species collected by
Alfred Russel Wallace (in
Longicornia Malayana),
Robert Templeton and other assiduous collectors but not prolific writers on
systematic entomology. He became a Fellow of the
Entomological Society in 1854, was president from 1864 to 1865, a Member of the
Société Entomologique de France and belonged to the Belgian and
Stettin Societies. He was also a Fellow of the
Linnean Society (elected 1852) and was on the Council of the
Ray Society. His 2,500
types are in the
Natural History Museum, London. ==Evolution==
