have not been determined. Anomala lucicola Faby. was present in 
considerable numbers, mostly on pine, though not uncommon on oak, 
from June 26 to July 19, and a few were taken as late as the 27th. One 
or more species of Dichelonycha occurred rather abundantly during 
the latter half of June and the first week of July. Monohammus scu- 
tellatus Say and M. titillator Fabr. were taken in very small numbers, 
though larvee which must belong to these species and to M. confusor 
Kirby appeared to be common enough in this locality. Glyptoscelis 
hirtus Oliv. was captured on hard pine in rather small numbers from 
June 4 to 26. The common pine weevil (Pissodes strobi Peck.) was 
obtained in large numbers on hard pine, it being specially abundant 
in June, but occurring in small numbers throughout July and in early 
August. Two other weevils (Magdalis lecontec Horn and M. alutacea 
Lec.) were also taken throughout June and during the first week in 
July in association with the white pine weevil. The former of these 
two was even more abundant than the Pissodes. 
Bark-borers.—The hard pines at Manor, Long Island, the white 
pines in the vicinity of Albany, and the balsam or fir trees of the 
Adirondacks have all suffered more or less from the attacks of various 
species of bark-borers. Investigations in all of these localities failed 
to reveal adequate cause for the great mortality among these trees 
unless it be due to the work of species of Tomicus. I am well aware 
that Dr. Hopkins, who has made a special study of bark-borers and 
is a well recognized authority on the group, inclines to lay blame on 
forms belonging in some other genus. The work of Dendroctonus 
terebrans Oliv. was very common at the bases of the hard pines on 
Long Island, and I found it in smaller numbers in white pines about 
Albany, but never in large enough numbers to cause very serious 
injury. In both of these localities, however, Tomicus calligraphus 
Germ. and 7. cacographus Lee. and, in some instances, other species 
were uniformly present and many of the trees bore many pitch tubes, 
the work in most instances of the first-named form. Tomicus callig- 
raphus was found by me last fall working in enormous numbers in 
dying white pines, the beetles not hesitating to run galleries into liv- 
ing, apparently healthy tissues, and so abundant was the insect that 
I eould not help thinking it responsible in part, at least, for the death 
of the tree. This month I have found undoubted evidence of Tomz- 
cus calligraphus’ entering what to every appearance were healthy 
trees. It is true there were not quite so many branches at the top of 
the tree closely inspected as there frequently is, but the needles 
were all green and gave no evidence of injury, and the bark from the 
base of the trees to the top was nice and green so faras the eye could 
discern, and yet such a one had been entered in large nuinbers by 
Tomicus calligraphus, and the beetles are even now running primary 
galleries and depositing eggs. The trunk of this tree was well spotted 
with pitch tubes, and small masses of pitch had dropped on the leaves
