Determined by H. S. Barber by comparison with specimens in the Baker Philippine collection determined by Weise and marked with a (?). Guam specimens have previously been determined as P. ping11is and P. puncticollis , but do not have the strong spine of front femora as in pinguis, nor the distinct puncturation of thorax as in puncticolris. An abundant chrysomelid, which sometimes defoliates mango trees. Many other kinds of trees are also fed on by this beetle. The larvae are unknown and nothing has been learned of the life history of the species. The species was described from the Philippines.
