Observations on Wood-boring Insects 
75 
Family Buprestidce 
Dicer ca lurida Fabr. One specimen, July 13. This species 
breeds commonly in hickory, although the present one came 
probably from an oak log. 
Chrysobothris femorata Oliv. One specimen, July 13. This 
is a common enemy of apple, but the larvae occur in several 
other deciduous trees. 
Family Dascyllidce 
Eucinetus morio Lee. One specimen, July 20. This has 
been taken beneath oak-bark and on fungi on oak. 
Family Dermestidce 
Attagenus piceus Oliv. Two specimens, July 26-28. This is 
the well known “carpet beetle” which develops in woolen mat- 
erials, feathers and other articles of animal origin. Weiss and 
West (Proc. Biol. Soc. Washington, vol. 33, p. 6 1920) record it 
from a fungus Lenzites betulinus so that its occurrence in the 
present series is probably not accidental. In country houses the 
larvae find food in the many flies and other insects that enter 
the walls, window casings, etc. for hibernation, many of them 
to die before the advent of spring. 
Family Ostomatidce ( Trogositidce) 
Thymalus marginicollis Chev. Two specimens, July 20. 
This species breeds in the common shelf-fungus of birch, Poly- 
porus betulinus. 
Family Nitidulidce 
Epurcea sp. One specimen. The members of this genus 
feed on fungi. 
Family Mycetophagidce 
Mycetophagus flexuosus Say. One specimen, August 23. A 
common fungus-beetle.
