far as adjacent trees are concerned, are those which show little 
pr no discoloration of the foliage and very few exit or “shot 
holes,” since these are the trees which contain the largest number 
of destructive borers. Pines which died the preceding year or 
earlier, while infested more or less by other borers, are not a 
menace to living trees. Furthermore, if satisfactory results are to 
be obtained by cutting out and destroying infested pines, it is es- 
sential that there should be cooperaticn on the part of all, since 
the bark borers fly: readily for considerable distances. 
Platypus punctulatus Chap. Numbers of this Central 
American borer were taken last August on Panama logs which had 
been shipped around the Horn and were then in the lumber yard at 
Astoria. The beetles were coming out in large numbers and attack- 
ing freshly sawn sappy mahogany in the 
yards, running longitudinal and, in some 
instances, vertical galleries into the wood. 
It was estimated that the injury in early 
August was as high as $200 a day. An- 
other Ambrosia beetle, namely, X yle- 
borus torquatus Eich., was also 
taken in some numbers on the mahogany 
logs. With the above were associated 
species Of Atilonium bidenta- 
Pimms Babee “Xuthia brevipes 
Sharp. and ~Palorus melinus 
Herbst. The Scolytids were kindly iden- 
tified by Doctor Hopkins through the 
courtesy of Doctor Howard, while the 
other Coleoptera were determined by 


Doctor Schwarz, both of Washington. Fig. 13 Dorsal view of

our attention was called to some eight or nine large pine. trees 
in the western end of Albany. These pines were very badly 
infested by this bark louse, the upper portion of the trunk and 
the under side of the larger limbs being nearly covered with the 
white cottony excretion. One tree was dead, probably having suc- 
cumbed to earlier attacks, while a second was in a dying condition. 
An examination of the latter showed that various borers had begun 
work under the thicker bark, and that in all probability the tree 
would die before the end of the season. It is possible that these 
trees, as in the case of park trees observed in earlier years, may
