tice though there was no evidence here of serious injury to liv- 

 ing- trees. Injury was also reported from Garden City. 



The work of this insect is easily recognized by the irregular, 

 anastomosing galleries traversing the inner bark and fre- 

 quently girdling the tree. Many of these galleries are only 

 about one-sixteenth of an inch in diameter, though the mature 

 grubs cut a channel nearly a quarter of an inch wide. The 

 beetle is nearly three-eighths of an inch long, black, and with 

 the wing covers marked with two golden yellow stripes as illus- 

 trated in the figure. The borer or larva is long, slender, flattened, 

 the part just behind the head considerably swollen, and a milk 

 white or yellowish color except the mouth parts and the pe- 

 culiar minutely serrate anal processes, which are dark brown. 

 This borer winters in its gallery, usually with the slender body 

 abruptly bent near the middle. The pupa is white like the 

 larva. 



This borer is a well-known enemy of chestnut and oak, there 

 being several records of serious injury in various parts of the 

 country. It would not be surprising if this outbreak was an in- 

 direct result of the chestnut blight. Most of the chestnuts 

 near Old Westbury, L. I. have been killed by the disease, 

 though there are still hundreds dead or dying and therefore 

 presenting favorable conditions for borer infestation. Beetles 

 issuing from the chestnut, in the absence of this food plant, 

 must necessarily concentrate their attack upon adjacent oaks 

 or perish. Since these borers winter in the affected trees, the 

 cutting out and removal or burning of the wood before growth 

 begins in the spring will do much to check the trouble and 

 thus destroy many borers which normally would mature and 

 attack other trees the following season. 



MISCELLANEOUS 

 Abia inflata Nort. The false caterpillars of this species were 

 transmitted by Leonard Barron from Garden City, N. Y., under 

 date of June 8, 191 1 accompanied by the statement that they 

 were destroying Lonicera in that section. 



Larva. Length when extended 2.2 cm. Head brownish, the 

 ventral third fuscous whitish. Body mostly yellowish and sooty 

 yellowish. There is down the middle of the back a broad, vari- 

 ably yellowish stripe broken by a series of median, quadrate or
