This quite large bee comes from the island of O'ahu, where it lived on the leeward hill sides of the Ko'olau Mountains, somewhat above Hawai'i's capital city of Honolulu.
It was found quite commonly in the years between 1892 and 1930, but could not be found again in later searches.
It is assumable, that the vanishing of certain native plant species (Boehmeria grandis, Pipturus albidus), which were host plants for the bee's larvas, played an importand role in the species' demise.
