Distribution in Canada and Alaska.

NB (New Canadian record). This Palaearctic species was first reported in North America by Fauvel (1871) and Fauvel (1889) from MA, MI, and TX in the USA, distribution typical for an adventive species; he also included LeConte’s record of subtilis (Erichson) from the "southern and western states", which LeConte confirmed; the last record of pusillus in North America was by Ulke (1902) from DC.

Natural history.

All but one of the specimens known from NB were collected at a u.v. light in a mixed forest in July, August, and September. One specimen was collected by treading vegetation in a black spruce bog in June.
