Descriptions of the Larvae of Some Ruteline Beetles with Keys to Tribes and Species (Scarabaeidae)1

Abstract

The subfamily Rutelinae reaches its greatest development in the neotropical region where the group is represented by 5 of the 6 known tribes (Blackwelder, 1944). In the United States and Canada only the two tribes Anomalini and Rutelini are represented but there is always the possibility that larvae of some species belonging to another tribe may be introduced as were larvae of the Japanese beetle, Popilliu japonica Newman, and the oriental beetle, Anomala orientalis (Waterhouse), both belonging to the tribe Anomalini. The injurious Chinese rose beetle, Adoretus sinicus Burmeister, is now well established in the Hawaiian Islands and from there might be carried to our west coast.
