Explanation of Names
Eumenes Latreille, 1802
=from one of two etymologically related Greek names, both of which mean 'gracious one, kind one, one of soothed mind':
(A) The masculine Εὐμένης (Euménēs), derived from εὖ ('eû') 'good' + μένος (ménos) 'mind' + -ης (-es) a suffix that forms an adjective from a noun. A given name of several historical figures, including rulers, a general, a sculptor, and a bishop.
(B) The feminine Εὐμενίς (Eumenís), derived from εὖ ('eû') 'good' + μένος (ménos) 'mind' + -ις (-is) a suffix that forms a feminine noun or adjective. The singular form of Εὐμενίδες (Eumenides), one of the winged goddess of vengeance in Greek mythology also known as a Fury. The name was used euphemistically for fear of invoking their anger. While this is a commonly-given etymology for the genus, this name is feminine whereas the genus Eumenes is taken as masculine. The name was also seldom if ever used in the singular in Greek.
