Insects Bred from American Larch 95 
reports it from The Palisades, N. J. Blatchley (1910, 
p- 715) records that this species “is known from Michigan 
and Wisconsin.” 
The only reference to the habits we have been able to find 
is the general statement regarding the genus by Smith (loc. 
cit.), that all the species occur under dead bark. We ob- 
tained but one specimen from larch and this was taken 
from punky wood April 28. It is believed that A. brevicornis 
breeds in decaying wood and under decaying bark, but we 
can offer no real evidence for this view. 
The insects associated in the decayed wood are Tenebrio 
tenebriodes and Dryophthorus americanus. If A. brevicornis 
breeds in such surroundings it would also often be associated 
with Stenoscelis brevis. The recently killed part of the same 
tree contained Phymatodes dimidiatus, Asemum moestum 
and Serropalpus barbatus. 
Phyllobenus dislocatus Say. 
Phyllobenus dislocatus has been reported from various 
parts of the United States: Hopkins (1893, p. 187), West 
Virginia; Hamilton (1895, p. 335), Pennsylvania; Felt 
(1906, p. 503), New York; Schaffer (1908, p. 127), Ari- 
zona; Wolcott (1909), Wisconsin and Ohio; Smith (1909, 
p- 303), New Jersey; and Blatchley (1910, p. 859), 
Indiana. 
This small clerid has been reported as associated — doubt- 
less in the capacity of a predator — with a large number of 
bark and wood-inhabiting forms derived from a variety 
of different trees. Hopkins (1893, p. 187) states that it 
“ Attacks Polygraphus rufipennis in Black Spruce and 
Pityophthorus consimilis in Sumach (Rhus glabra) and 
with Scolytus regulosus in Apple bark.” According to Felt 
(1906, p. 449), LeConte reared it from hickory twigs con- 
taining Chramesus hicoriw. Felt (1906, p. 503) reared it 
from hickory limbs infested with Chrysobothris femorata, 
and Magdalis olyra. Blackman (1915, p. 54) records having 
bred P. dislocatus from limbs of pine containing Pityogenes 
hopkinsi and no other borer, and Chapin (1917, p. 29)
