Employed by the Comission for Overseas Pest Research in the 1970s when he was based in the Caribbean, but he seems otherwise to have been associated with North Wales and Anglesey. Max Barclay (BBI website 17.9.2006) noted that a collection of beetles made by Mitchell was acquired by the NHM in 1998, and that it was composed of about 50% British and 50% foreign, mainly Caribbean. ‘The collection is listed as having been presented by 'P. Mitchell' so I suspect the collector may be dead. It was presented to the Hymenoptera Section, but beetles filtered through to me some time later. Identification of this collection is now complete and it contains some new county records (UK) and an impressive undescribed species from among the tropical stuff.’ (MD 11/09)
