NOVA SCOTIA: 54 specimens examined from Antigonish, Cape Breton, Halifax, Kings, Pictou, and Queens counties. The earliest record is from 1962 (Kings Co.: Berwick, 28.viii.1962, H.T. Stultz, ACNS). PRINCE EDWARD ISLAND: Queens Co.: St. Patricks, 14.vii.2002, C.G. Majka, red spruce forest, CGMC.

Newly recorded in Nova Scotia and Prince Edward Island. Scattered records from across the region (Figure 7) [Specimens of M. dislocata from NB were not available for examination; consequently they are not plotted on the distribution map.]. In Point Pleasant Park, Nova Scotia, found in association with the galleries of Scolytinae feeding on red spruce ( Picea rubens) and white pine ( Pinus strobus). The most abundant scolytines found in these galleries (75% of individuals) are Hylurgops rugipennis pinifex, Trypodendron lineatum, and Polygraphus rufipennis in spruce, and Ips pini, and Pityogenes hopkinsi in pine (C. Majka, unpublished data).

Associated with bark beetles in oak ( Quercus), juniper ( Juniperus), cedar ( Thuja) ( Cupressaceae), hickory ( Carya), pine ( Pinus), hackberry ( Celtis occidentalis L.)

( Ulmaceae), black spruce ( Picea mariana (Mill.) BSP.), butternut ( Juglans cinerea L.) ( Juglandaceae), redbud ( Cercis) ( Brassicaceae), and other hardwoods (Opitz 2002). Knull (1951) reported it as predaceous on Anelaphus villosus (Fabricius) (Cerambycidae), Bitoma carinata (LeConte) (Colydiidae), Chramesus hicoriae LeConte (Curculionidae), Hylocurus sp., Scolytus muticus Say, S. rugulosus Ratz., Pityophthorus dentifrons Blackman, P. consimilis LeConte, and Polygraphus rufipennis (Kirby) (all Scolytinae).
