eastern United States, since it has been listed from Ohio, southwestern 

 Pennsylvania, New Jersey, and it occurs in the edge of the Adirondacks in 

 New York. 



Centrodera decolorata Harr. 



A slender, light brown beetle about an inch long, bores in butternut and beech. 



A single sQecimen of this uniformly light browm beetle was sent to us 



by George S. Graves of Newport N. Y., Jan. 5, 1903. It was cut out from 



a butternut tree, and Mr Wickham states that 



it has been found by Mr Harrington on beech. 



This beetle is a rather slender insect almost 



an inch in length. The antennae are rather 



stout, not quite equal to the body in length, and 



both they and the legs are a little darker than 



th*; wing covers. Head dark reddish with 



coarsely granulated black eyes ; thorax sub- 



cylindric, longer than wide, and armed with 



stout, lateral spines. Wing covers long, slender, 



closely punctured, and with two indistinct ridges. 



This species has been listed from New Jersey, District of Columbia and 



southwestern Pennsylvania, being somewhat rare in the latter two localities. 



Sesia corni Hy. Edw. 



A purplish black, yellow-marked, red-tailed clearwing moth, witli a wing expanse of 

 about ^4 in<"h, bores in the larval stage in maple. 



This interesting form infests the branches and twigs of maple which 

 are often enlarged at several points by rough bark or gnarled excrescences. 

 These are often nearly globular, more frequently, however, oblong and not 

 unusually there are openings into the center of the stem. An examination 

 of the wood shows that it may be mined in various directions and in a 

 decaying condition. The attack often causes branches to die or so weakens 

 them that they are broken by winds. One or more larvae may be found in 

 a single enlargement. Adults are abroad from about the middle of May to 

 the middle of June.
