This first post is my newest acquisition: It's undated but the text suggests written in the early 20th century (there's a brief description of the Large Blue pupae but no mention of it's association with ants and there's no mention of the Chequered Skipper's occurrence in Scotland for example). The author is written as W. E. Kirby which is almost certainly a typo, a William Forshell Kirby was a prominent entomologist of the time (1844 - 1912) who's name crops up elsewhere in my collection.
The plates are attractive and as with some other books of the time silver rather than white was used on several of the Fritillaries, making them very eye catching but difficult to photograph accurately, especially with flash. This book lists a total of 74 butterflies although many of these are already stated as being probably extinct (Purple Edged Copper, Mazerine Blue etc.) Others we now know not to be true species any more, in this book we had 3 species of Brown Argus: and there was another species of Copper too: The rutila being described is almost certainly L. dispar rutilus but it's occurence in Kent is, well

Most of the Common names are recognizable but a few could be misleading to todays eye's, the Large Heath is called the Marsh Ringlet and the Gatekeeper is referred to as the Large Heath.
Most of the natural history such as foodplants etc. is pretty accurate too, although there are expected notable holes in knowledge such as the Large Blue lifecycle. Some of the foodplants listed are however a bit.... "really?" The Duke of Burgundy is said to feed on Primrose and Docks, the Brown Hairstreak 'feeds on Blackthorn, Birch, and similar trees' (The Birch foodplant being how it came about it's species name, Betula being the genus to which Birch's belong). These errors are all part of the charm of these old books though

Along with the butterflies there are also descriptions and images of 987 moths, and almost comically at least with the images, Kirby dipped his toes into the murky world of Micro lepidoptera. I'm not sure how anyone could have Identified the smallest moths from the images which seem to be lifesize. Anyway I hope some of you find this as interesting as me and if anyone else has ald books they want to share I'd love to some 'best bits'
