Patronym for Hermann August Hagen (1817-1893), a German entomologist who, at the invitation of Louis Agassiz, emigrated to Cambridge, MA in 1867 to become an assistant in entomology at the Museum of Comparative Zoology at Harvard. There he developed the department of entomology at Harvard, and in 1870 was made professor of that science, being the first professor of entomology in an American university.
Grote (1874) original description is online in the print references.
