The Serricornia^ orsaw-horned series,begins with the familyDascyllidcE, containing mostly small formsfound on dead or dy-ing trees or branches,in which the larvae probably live. None are of economic importance, a fact which is also true of the next family, latter, indeed, contains only five species, all accountedrarities in collections, and believed to breed in cedars. The family Elateridce, spring beetles, click-beetles, or snapping-beetles, contains numerous troublesome forms, andis easily distinguishable in all its stages. The beetles have theprothorax very loosely jointed to the rest of the body, and on the under side a curved^^ ^ ^ process fits into a cavity of the a specimen isplaced on its back itbends the extremities soas to raise the middle of
