Centrodera decolorata Harr. 

 A sieiultr, light brown beetle ;ib()ut an in( li long, bores in butternut and beech. 

 A sino-le specimen of this uniforml)- light Ijrown 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 lengtli. The antennae are rather 

 stout, not (|uite ecpial 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 sui)- 

 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 H). Kdw. 



A |nir])lish black, yellow-marked, red-tailed clearwing moth, with a wing e-vpanse of 

 about i{^ inch, bores in the larval stage in maple. 



This interesting form infests the branches and twigs of maple which 

 are often enlarged at sevt-ral points by rough bark or gnarled excrescence.s. 

 These an- often nearly globular, more frequentl)-, however, oblong and not 

 unusually there are openings into the center of the stem. An e.xamination 

 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 inore larvae may be found in 

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

 the iniddle of June.
