The Cleridæ are a rather small family of beetles, but make up for their comparatice scarcity by the beauty of form and colour shown by many of them. As a rule, they may be easily recognized by their resemblance to a few common types such as are found in all cabinets, and agree in possessing the followiong family characteristics: The antennæ are usually serrate, with the outer joints enlarged, forming an open or more rarely a compact club; the tarsi are five-jointed, the first or fourth joint often very small and indistinct, all but the fifth furnished with membranous appendages.
