The genus Bomhus is widely distributed; its number of species amounting to little 
short of one hundred. Bomhi are found both in the Old and New World, a few species 
occurring in the Tropics; the genus has not been observed to penetrate Africa beyond Algeria, 
and it has not been found either in Madagascar, Australia or New Zealand. In the Old World 
it has been found in Lapland, Siberia, Kamtschatka, China, Japan, India and Java. In great 
Britain twenty species occur. In the New World, it has been found in Greenland, Boothia 
Pelix, and at the Great Bear Lake, within the Arctic Circle. Mexico has produced some 
of the most beautiful species of the genus; North America is rich in species; in South 
America several fine ones occur.
