Zaharia NECULISEANU Poecilus lucublandus (continued) l.In these chambers were found the larval exuviae. The total duration of the larval stage - 30-32 ds . Cannibalism was observed only for L2 and L3. 2.The first pupa was observed in Mid- June, the last in early September. The length of pupa was 8.8- 9.2mm, its width was 3.8—4.0 mm . The pupal stage lasted 6—7 ds. New adults which usually emerged from the pupae from Mid- July to early September. The adults and larvae live along the edge of bodies of water, under stones, bark, logs. Both adults and larvae are predators. This species is known from North, Northeastern, Eastern, and Western North America. Pterostichus Bonelli is a large genus, varying from moderate to large size. The beetles are black, stout, with short appendages. Of the 40 species known from northeastern North America, 10 species occur in the JBWR. 3.The Pterostichus melanarius (14-20 mm) is large carabid species, distinguished by denticulate hind pronotal angles, with sides of pronotum hardly sinuate and basal impression broad, foveate. Overwintering as larva, seldom as adult, was collected in pitfall traps in the autumn; This eurytopic, introduced (from Palearctic) predator species has a wider distribution also to North America, it well adopted to open habitat, in many agricultural field, but also occur in the forest and in the gardens. 4.The Pterostichus commutabulis (7.0-9.0 mm) was found in moist leaf-litter under moss in autumn, but usually can be found in dead wood. Adults have black body, markedly shiny, reddish appendages, pronotum rounded from apex to base, sides on basal Vi explanate, deep, linear, parallel, impunctate basal impressions; elytra iridescent with deep, impunctate elytral striae. 5.This is Pterostichus trinarius, a relatively small (11-14 mm) ground beetle, was taken under reed in dry habitat in October and November. Adults have black, shiny head and pronotum, purplish elytra, with 3 dorsal punctures. 6. Pt. patruelis (6-8 mm). Black, somewhat shiny reddish brown, appendages with tibiae and antennomere base, of same, piceous. Collected in pitfall traps installed in the reed in Mid- August and under debris. 70 5 6 4 3
