My particular A question I am often asked is “How can I get thanks to John Bratton for sending three articles and my started on beetles?” and another is “What is the best apologies to him and to other authors for the delay in field guide to beetles?”. The second question is easy publishing some articles. to answer, there are no true field guides to beetles as most species cannot be identified in the field! The In spite of the difficulty of obtaining enough material, I first is more difficult. In order to help beginners intend to continue producing Beetle News. However, I have familarise themselves with the more distinctive decided to reduce the planned number of issues from four to species, and also to recognise beetle families more three each year. easily, I have been working on a simple onscreen guide using photographs of set specimens. This will show over 2,000 species, more than half of British beetles, including all of the more distinctive species and at least one representative from each genus, except for the smallest and most difficult groups. A sample screenshot is shown opposite, though obviously the quality is much better in the actual product. This guide will be made available as a free download. I had hoped to complete it by now, but although 90% complete we have now entered the main survey season and time is at a premium. It will certainly be ready by the next issue of Beetle News, where full information will be available, but the first announcement will be made on the beetles- britishisles group : http://tech.groups.yahoo.com/group/beetles- britishisles/ 1 Beetle News Vol. 4.1 May 2012 ISSN 2040-6177 Beetle recording in Gloucestershire – an appeal for Beetle recording in Cornwall – an appeal for records records The most up-to-date review of Cornwall’s beetle fauna Coleoptera of Gloucestershire was published by David was published as part of the Victoria County History in Atty in 1983.

Andrew Duff 110 Cromer Road Used sensibly, where records are first sorted by West Runton country, the ‘Typomap’ system might have some Norfolk merit, although hardly anyone now knows what the NR27 9QA abbreviations stand for. However in an electronic age of databases and spreadsheets, where unique Balfour-Browne’s ‘Typomap’ system of two-letter codes are required, the system simply doesn’t cut it. subcounty abbreviations is briefly described in A Having recently tried to understand the late Leslie Coleopterist’s Handbook (Cooter & Barclay, 2006: Frewin’s card index of beetle records, which used 327-328). However these authors failed to point out the ‘Typomap’ abbreviations but didn’t specify a fundamental flaw of this now largely outdated which country was being referred to, I can vouch sytem: the two letter codes are only unique within for just how confusing this can be, more especially each country, not within the British Isles as a whole. as he collected widely in Britain and Ireland.

At the end of a hot afternoon's collecting with Mike Howe in the National Trust's Erddig Park, SJ3247, vice-county Denbighshire, on 16 May 1998, I picked up a 6.5 mm long (measured from the tip of the elytra to the tip of the rostrum), brown, scale-covered weevil beside a sap-run on a beech. Weevils are not a group I routinely try to identify, but I was under standing orders from my then line manager Adrian Fowles to collect all weevils I found in Wales, so this one went into the pot and was passed to Adrian a few days later. He quickly realised it was not a weevil known from Britain, nor did it appear to be a Europe- an species. The first consequence was that Mike re- ceived a late-night phone call asking whether he had actually seen me take the weevil. Once I had per- suaded Adrian it was not a practical joke, it was dis- patched to Howard Mendel in the Natural History Museum, where it was recognised as Antipodean. At the end of July 1998 Howard sent the following e- mail. “Richard Thompson had one last search of the col- lections to identify John Bratton's mystery weevil, before sending it off to Australia - and managed to identify it. It is Achopera alternata Lea. We have two specimens in the collection, from Tasmania, but John's specimen better matches the form of the spe- cies described from Eastern Australia.” I can find no information on the web about the biolo- gy of this species and cannot offer any explanation of how it arrived at Erddig. A gift shop selling peat-free plants is advertised on the Erddig web page but there doesn't appear to be an extensive garden centre. The weevil was caught in semi-natural parkland well away from buildings, and there is no reason to sup- pose the National Trust was involved in its occur- rence at Erddig. A. alternata has since been found a second time in Britain, in Hertfordshire, according to the website of the Watford Coleoptera Group (Thewcg.org.uk).
