Maps of Solar Eclipses from 1780 to 1799
The long-running series of the first eclipse maps to be included in ephemerides comes to an end with the 1781 eclipse. Eustachio Zanotti took over the publication of the ephemerides in 1750 from his teacher, Eustachio Manfredi, and continued through his third published volume spanning the years 1775 to 1786.
It would be several decades until the British Nautical Almanac began publishing eclipse maps in 1834. After a renaissance of eclipse maps in the early 18th century, the publication of new eclipse maps was temporarily decreased.
Annular Solar Eclipse of 1781 April 23
For the eclipse of April 23, 1781, Mademoiselle de St Laurent of France drafted this interesting eclipse map. It is fascinating because it combines an accurate rendering of an eclipse identical to the form of modern eclipse maps against a cartographic background of uncertain and unknown continental boundaries. This map eloquently speaks to the fact that the state of astronomical calculations in the 18th century was considerably more advanced than the geographic knowledge of the world.

Total Solar Eclipse of 1788 June 4
This page from the massive Iconographic Encyclopedia of Science, Literature, and Art by Johann Georg Heck features an eclipse map. A nice quality of this map is the progressive shading in the penumbral, simulating the darkening partial shadow.
