Observed during 1885-86 [at Chapel Hill, North Carolina]- 
ufests peach, plum, and cherry trees, and has recently done 
onsiderable damage in this country, notably in the South. The 
'eight of opinion indicates that only diseased trees are injured, 
^hen attack on healthy trees is attempted, the insect is driven 
ut by exudation of gum. Has seen sound limbs of healthy 
•each-trees punctured in this way, but no evidence of eggs be- 
ng deposited nor of the larvae at work. This bleeding may lead 
oa diseased condition of the tree, and thus later afford mate- 
ial for the beetle to work upon. 
Number of generations in this latitude is probably two. In 
ate spring (May) and early autumn (September) beetles exca- 
ate galleries to deposit eggs. These galleries are from half to 
hree fourths of an inch in length, the opening being just the 
liameter of the beetle but the gallery a little larger. When the 
ggs are deposited the female retreats to the entrance, where 
he remains to guard her young, even in death blocking the en¬ 
hance. Quotes Eichoff on this habit. 
From specimens in the laboratory two parasites were bred; 
Jhiropachys colon , Linn., and Eupelmus sp. The adult parasites 
•scape by cutting cylindrical holes through the bark. Eupelmus 
s quite likely a secondary parasite, preying upon Chiropachys. 
tn examination of infested peach-trees shows the parasite to be 
juite abundant.

Reports finding plum twigs in Edwards county, Illinois, dry 
md shriveled and mostly defoliated, as if affected by blight. 
Vlinute holes at bases of several buds, formed by beetles discov¬ 
ered in burrows and identified as Xyleborus pyri. Brief descrip¬ 
tion and biography of this species. Suggests cutting off and 
eurning these twigs before the beetles escape.

Gives brief sketch of history of insect in America. First de¬

ing the twigs of cherry-trees; and next received from Villa 
Ridge, Pulaski county, where Mr. Geo. W. Endicott had noticed 
it in the trunks and larger branches of the Chickasaw plum. 
Bark of plum branch profusely perforated with holes scarcely
