These are beetles, mostly from southern Asia except the last one, Dexoris, which is from Sierra Leone. These specific beetles became British (perhaps posthumously) and were recorded in Illustrations of typical specimens of Coleoptera in the collection of the British museum. Part 1. Lycidae by Charles O. Waterhouse.
The illustrations in this book are all credited to Edwin Wilson in the front material and in the Biodiversity Heritage Library entry for the book. But the last two plates have “Edw. A. Smith del et lith” underneath. I’m pretty sure “lith” is “lithographer,” but whether “Edw” is “Edward” or “Edwin” (or “Edwina” or “Edweard”) is beyond me. Maybe the “A” should be a “D” and these are by Edwin Dalton Smith? No idea.
But he did some lovely antennae. especially on that fellow in the middle, Atelius expansicornis, a well-named (and expansively horned) net-winged beetle from Sri Lanka who still inspires young scientific illustrators today.
