also sometimes found in Pennsylvania; but he does not 
appear to have known anything of its histoiy. It is also 
found in Massachusetts, but has been rarely seen until 
within a few years. One of my specimens was taken in 
i\Iilton about twenty years ago, and several others were 
taken in Cambridge, during the summers of 1843 and 1844, 
upon the European lindens, from the tmnks and branches 
of which they had just come forth. A knoAvledge of the 
habits of this insect might have led to its more frequent 
discoverv. One of the lindens above named Avas a noble 
and A’enerable tree, Avith a trunk measurino; eiMit feet and 
' o o 
fiA^e inches in circumference, three feet from the gi'ound. 
A strip of the bark, tAvo feet Avide at the bottom, and 
extending to the top of the trunk, had been destroyed, and 
the exposed surface of the Avood Avas pierced and grooA^d 
Avith countless numbers of holes, AAdierein the borers had 
been bred, and AAdience SAA^aims of the beetles must haA’e 
issued in past times. Some of the large limbs and a portion 
of the top of the tree had fallen, apparently in consequence 
of the raA^ages of these insects ; and it is a matter of suiq^rise 
that this fine linden should haA^e Avithstood and outliA^ed the 
attacks of such a host of miners and sappers. 
The lindens of Philadelphia haA^e suffered much more 
seA^erelv from these borers. Dr. Paul SAAnft, in a letter 
AATitten in iNIay, 1844, gaA’e to me the folloAAung interesting 
account of them. “ The trees in AVashington and Inde¬ 
pendence Squares Avere first obseiwed to haA^e been attacked 
about seA^en years ago. Within tAvo years, it has been found 
necessary to cut doAvn forty-seA^en European lindens in the 
former square alone, AAdiere there noAV remain only a feAV 
American lindens, and these a good deal eaten.” “ Many 
of the beetles Avere found upon the small branches and leaA^es 
on the 28th day of iMay, and it is said that they come out 
as early as the first of the month, and continue to make 
their Avay through the bark of the tnink and large branches 
during the AAdiole of the Avarm season. They immediately fly
