[In the accompanyingfigure, the larvse and the beetles arerepresented in their natural sizes,feeding upon a twig of grapevine.]Mr. George C. Snow, of Penn Yan,N. Y., has sent me an insect whichhe detected preying upon the larvaby sucking its juices. They wereHemipterous, belonging to the plantbugs, of which so many are knownto be valuable aids to us in thedestruction of our insect foes. AsI could not recognize it in its pupalstage in which it was received (June 26tb), it was submitted toMr. Uhler, and was referred by him to the genus Fodisus, and prob-ably of the species modestus (Dallas)..

A destructive borer of the tips of rose bushes has made its appear-ance at Ausable Forks, N. Y., during the past summer, which hasonly been observed in its larval stage, and therefore can not benamed at present. It apparently belongs to the Tenthredinidae, orsaw-flies. Its form of injury is to commence at the extreme tip andburrow downward several inches, consuming the entire interior ofthe stem. Some of the infested tips were sent to me during themonth of June, and were inserted in damp sand for maturing thelarvse which they might contain.
