Another Philippine species considerably larger than Anomala sulcatitla Burmeister. It is probably the species whose grubs were found at pineapple roots by Fullaway in 1911, and mentioned as Lachnosterna species by Vandenberg in the 1930 report of the Guam Agricultural Experiment Station . At present they are injurious to corn roots in some places. The beetles are nocturnal, and feed sometimes destructively on banana leaves. Determined by F. X. Williams.
