REPORT OF STATE ENTOMOLOGIST 1899 539 
Locust borer (Cyllene robiniae Foerst.) Some half dozen 
of the pretty beetles belonging to this species were received September 
20 from J. H. West of Poughkeepsie N. Y., with the information that 
they had practically destroyed a very handsome young locust tree, 
which to within two years had been in excellent condition. The attack 
was first observed in the early fall of 1897. ‘The trunk, about 6 inches 
in diameter, was full of holes to within r5 or 20 feet from the ground 
and “the outside was covered with these bugs to the top.” The tree 
was treated with benzine and washed several times with a stream from a 
hose. ' Last year no insects were noticed, but for the past few weeks the 
beetles have been very abundant. Several limbs and one of the two 
main trunks were so badly riddled with burrows that they broke with 
their own weight. A portion of the infested tree, which came to hand 
later, showed that the above account was not an exaggerated one. The 
interior of the branch, one of the best on the tree, was badly honey- 
combed with burrows and here and there, where the beetles had emerged, 
the bark was badly undermined and perforated. The tree had evidently 
been oviposited on freely, as irregular clusters of ovoid white eggs, 
about + inch long and 51, inch in diameter, were found in cavities beside 
some burrows, and single eggs, tucked in longitudinal crevices of the 
young bark, were numerous. 
Elm leaf beetle. In Albany, Troy and vicinity this pest, Galeru- 
cella luteola Mill. has been as injurious as in preceding years, 
except where it has been controlled by spraying with arsenites. As it 
has established itself in force at Worcester Mass. and in a number of towns 
in the same county, all of which are probably within the transition life zone, 
it is very likely that in the course of time this beetle will make its way over 
a much larger portion of the state of New York than it has hitherto been 
supposed the insect could occupy. But I have yet to learn of its establish- 
ing itself in territory in this state outside the upper austral life zone, 
though it probably will, if it can exist in the places named in Massachu- 
setts. In both Albany and Troy large amounts of arsenate of lead have 
been used with most excellent results, when the applications have been 
timely and thorough. W. H. Swift & Co.’s prepared paste was used at 
the rate of 4 pounds to 200 gallons of water. In Troy over 1500 pounds 
of this insecticide was applied to the trees, and the person using it was 
highly pleased with the results, specially as the poison was found in the 
autumn on fallen leaves last sprayed May 22. Probably an 
equal amount was used in Albany. ‘Troy furhishes an interesting exam- 
ple of what the elmleaf beetle can do. Its ravages there have been
