Notes.

Litargus tetraspilotus LeConte is newly recorded from Prince Edward Island. Klimaszewski and Majka (2007) first reported this species in Nova Scotia. There are many records from the southern mainland of Nova Scotia, Cape Breton Island, and Prince Edward Island (Fig. 1). Records from New Brunswick and the northern mainland of Nova Scotia are lacking, but it is probable that it is found throughout the region.

In the Maritime Provinces Litargus tetraspilotus has been collected in many habitats including coniferous, deciduous, and mixed forests, seashores, coastal barrens, grasslands, marshy areas, a sandy pine barren, and an old field ecosystem. Specimens have been collected on the foliage of white pine ( Pinus strobus L.), jack pine ( Pinus sylvestris L.), red spruce ( Picea rubens Sarg.), balsam fir ( Abies balsamea (L.) Mill.), on deciduous, and herbaceous vegetation, on bristly sarsaparilla ( Aralia hispida Vent.), and in a rotting mushroom. Klimaszewski and Majka (2007) reported Litargus tetraspilotus as an inquline inhabitant of oak apple galls on red oak ( Quercus rubra L.) induced by Andricus (Callirhytis) sp. ( Cynipidae ) wasps. Rauf et al. (1985) found it on jack pine, Tucker (1919) found it on American mistletoe ( Phoradendron flavescens (Pursh) Nutt., and Ulyschen and Hanula (2010) reared it from decomposing loblolly pine ( Pinus taeda L.) logs in South Carolina.
