NOTES FOR THE YEAR 



The forest tent caterpillar occasioned no complaint and the elm 

 leaf beetle caused very little damage, this latter being due in all 

 probability to the frequent and rather heavy rains of the spring 

 and early summer. 



Incidental investigations in connection with the codling moth 

 work showed that the leaf roller was not nearly so abundant in 

 western New York as in 191 5. The red-humped apple tree cater- 

 pillar, Schizura concihnaSm. & Abb., was unusually 

 abundant on young apple trees in southern Rensselaer county. 

 The gregarious habit of the caterpillars makes the work of this pest 

 unusually conspicuous and is apt to excite apprehension out of 

 proportion to the actual injury caused, particularly as most of the 

 feeding comes so late in the season that the trees are rarely badly 

 injured by the loss of foliage. 



The reception of a horn-tail larva, possibly that of Adirus 

 trimaculatus Say, boring in rose shoots at Woodhaven, was 

 unusual and may mean the introduction of a new rose pest. The 

 material was so scanty that positive identification was impossible. 



The recently introduced European hornet, Vespa crabro 

 Linn., has evidently become well established in the vicinity of New 

 York City, and observations in midsummer on lilacs at Rye showed 

 that a number of smaller twigs were partially girdled and that one 

 or two bushes had lost leaders with a diameter of over one-half of 

 an inch through the activities of this hornet. A somewhat extended 

 account of this insect may be found in Museum Bulletin 180, pages 

 71-72. 



The reception during the past season of tips infested by the pine 

 twig moth, Evetria buoliana Schiff ., from Buffalo and New 

 York City, indicates the continued existence of this pernicious borer 

 in widely separated localities. A detailed account of this species 

 is given in Museum Bulletin 180, pages 39-42. 



FRUIT TREE INSECTS 



Apple tent caterpillar (M alacosoma americana Fabr.) . 

 Continued abundance of this common pest was noted in many 

 localities though the injury was greatly lessened by the copious 

 spring and early summer rains producing such a vigorous growth as 

 to keep the trees in partial leafage in spite of the caterpillars. The
