It was sunny and the air temperature was near 5°C when the adults were collected, although the surface of the log was <b>Map 32.</b> Collection localities in New Brunswick, Canada of <i>Silusa densa</i>. considerably warmer. One adult was also collected under tight bark of a dead standing balsam fir (<i>Abies balsamea</i> (L.) Mill.) during late May. Collection method: hand searching subcortical habitat. <b>Distribution in Canada and Alaska.</b> AB, <b>NB</b> (Klimaszewski et al. 2003; Gouix and Klimaszewski 2007). Th e presence of this species in New Brunswick suggests a much wider distribution in Canada. <b>Tribe Placusini Mulsant and Rey, 1871</b> <b> <i>Placusa incompleta</i> Sjöberg, 1934</b> Fig 33, Map 33 <b>New Records.
