OLD HOUSE BORER ( Hylotrupes ba.julus L. )

powder-post beetles practically completely destroyed the 
timbers of a barn 40 by 60 feet* 
ANTS (Formicidae) 
T. H. Parks (May 21): Complaints of damage by ants to 
lawn grass have been received regularly during the month. 
We have had very dry weather during the past eight weeks, 
which may be responsible. 
R. H. Pet tit (May 16): Ants are very plentiful in lawns 
and in dwellings this year. 
I'.. H. Swenk (May 13): Complaints of injury in lawns and 
gardens, and annoyance in' houses by ants, have continued 
to come in abundantly during the period here covered. As 
during the early part of April, these have mostly related 
to Formica fuse a L. doing injury out of doors. Ants 
reported as annoying in houses included the little red ant 
( .ionomorium pharaonis- L.), the common large carpenter ant 
( Camponotus herculeanus pennsylvanicus DeG. ), and one case 
each of the field ant' ( Lasius niger neoniger Emery) and 
Prenolepis imparis Say, the two last mentioned species 
from Holt. County and Colfax County, respectively. 
R. L. Parker (May 22): Ants were reported on peony at 
Kansas City. Carpenter ants were reported in a house at 
Manhattan and in' lawns and strawberry beds in Kansas City, 
Kans. and Mo. Red ants were reported in lawns and a base- 
ment at Kansas City, Mo. 
IT. L. Douglas (May 15): Quite a few of the native ants, 
such as the honey ant, fire ant, tiny black ant, etc., are 
shoeing up now in Yalobusha, Grenala, and Montgomery Counties. 
ARGENTINE ANT ( Iridomyrmex humilis Mayr) 
E. N. Cory (May 27): The Argentine ant was found in the 
Clifton Park greenhouses on February 6, and subsequently in 
the Carroll Park and Druid Hill Park greenhouses in Baltimore, 
but not in any commercial greenhouse establishment. 
(Identification by M. R. Smith.) 
N. D. Peets (May 21): The poisoning campaign against the 
Argentine ant conducted in March, 1930, seems, so far, to be 
giving excellent results. Numbers have reported as not being 
bothered with ants, while no one has reported any complaint 
in Copiah, Simpson, Lincoln, Lawrence, and Jefferson Davis 
Counties.
