Omus dejeanii Reiche, 1838

Omus dejeanii Reiche, 1838: 299. Type locality: "versant occidental des montagnes rocheuses, dans le district d’Oregon, aux États-Unis de l’Amérique du Nord" (original citation, see page 297), herein restricted to Bull Run, Clackamas County, Oregon (see Casey 1916: 8, as Omus dejeani foveatus ). Syntype(s) probably in MHNP. Etymology. The specific name was proposed in honor of Pierre François Marie Auguste Dejean [1780-1845], a French military officer who held the title of aide-de-camp to Napoleon Bonaparte from 1813 to 1815. Forced to leave his country in January 1816, he was able to come back in 1818 thanks to the relations of his father. At the death of this one in 1824, Dejean inherited his double title of count and pair-de-France. In 1844, Dejean was awarded the rank of "Grand Croix" (the highest) of the prestigious order Légion d’Honneur.

Omus dejeani robustus Casey, 1916: 7. Type locality: "Seattle [King County], Washington" (original citation). Two syntypes in USNM [# 45800]. Synonymy established by Horn (1926: 54).

Omus dejeani foveatus Casey, 1916: 8. Type locality: "Bull Run, Clackamas Co[unty], Oregon" (original citation). Two syntypes in USNM [# 45801]. Synonymy established by Horn (1926: 54).

Distribution.

This species, also known as the "Greater Night-stalking Tiger Beetle", is found from southwestern British Columbia, including Vancouver Island, to southwestern Oregon [see Pearson et al. 2006: Map 6]. The record from northern California (Leng 1902: 105) needs confirmation; that from “Montana” (Leng 1902: 105) is in error.
