James Joseph Francis Xavier King

James Joseph Francis Xavier King F.E.S. (1855–1933) was a Scottish entomologist, artist, librarian and lecturer at the Glasgow School of Art and Glasgow and West of Scotland Technical College.

Biography King was born on 28 August 1855 in Burnside Street, Glasgow, Scotland. King's father George and his mother Catherine (née Kennedy ) were both originally from Dublin, Ireland.

In 1871, fifteen-year old king was recorded on the Scotland Census as an Architectural Apprentice.

King became a member of the Glasgow Natural History Society in 1872 at the age of sixteen, and served as the Society's Librarian from 1883.

By 1880 King was teaching general classes at the Glasgow School of Art.

King exhibited two landscapes at the Glasgow Institute of Fine Arts in 1885 and is recorded as being an active artist between 1885 and 1891.

In 1892 King married Jessie Parker Barr (1864–1933).

In 1896 King's death was erroneously reported in the Dundee Evening Telegraph as having occurred in a hotel at Fochabers on 14 September; King himself wrote to the newspaper to correct them - he had been mistaken for his friend the botanist Thomas King, who had actually died in Fochabers on that date.

King died at Kelvinside, Glasgow, on 5 February 1933.

During his lifetime King had assembled a large collection of British insects (c.500,000 specimens Another oil portrait sketch of King by John Lavery is in the collection of the Glasgow Museums Resource Centre (GMRC).

Entomological work Many of King's entomological investigations were conducted in Scotland and Ireland.

In 1876 King contributed a list of western Scottish Lepidoptera to Peter Cameron's list of Insects published in On the fauna and flora of the west of Scotland.

In 1878 King collected a male example of the caddisfly species Limnophilus subcentralis at Aviemore, Inverness-shire, which was the first time that the species had been recorded in the British Isles.

On 27 July 1885 while on his summer holiday and travelling through Glen Tromie near Kingussie, King encountered a cloud of caddisflies of the species Hydropsyche instabilis which he calculated was about five miles in extent, and was dense enough with individuals for King to collect 50–60 insects with one sweep of his insect net. King returned a few days later and found none of the caddisflies remained in the area, and he attributed the phenomenon to changes in the weather.

At the beginning of 1895 King spent ten weeks at Unst, Shetland, in the company of Percy Bright and William Reid. All three men were searching for Shetland Lepidoptera, but King also collected Trichoptera specimens.
