have not been determined. Anomala lucicola Fabr. 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. Monoliammus scu- 

 teUatus Say and 21. titillator Fabr. were taken in very small numbers, 

 though larvae which must belong to these species and to Jf. confusor 

 Kirby appeared to be common enough in this locality. Glyptoscelis 

 liirtus 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 earl}" 

 August. Two other weevils {Magdalis lecontei Horn and J/, cdutacea 

 Lee.) 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. 



Baric-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 T. cacograplius Lee. and, in some instances, other species 

 Avere uniformly present and many of the trees bore man}' pitch tubes, 

 the work in most instances of the first-named form. Tomicus callig- 

 raplius w^as found by me last fall working in enormous numbers in 

 dying white pines, the beetles not hesitating to run galleries into liv- 

 ing, apparentl}" health}^ 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 Tomi- 

 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 far as the ej^e could 

 discern, and yet such a one had been entered in large numbers by 

 Tomicus calligraplms, and the beetles are even now running primary 

 galleries and depositing eggs. The trunk of this tree was Avell spotted 

 with pitch tubes, and small masses of pitch had dropped on the leaves
