Throughout the State but scarce. April ^* after FoS^' J—August 26. Often found in the washup along the beach of Lake ^Michigan. One specimen from Putnam County presents a curious color a ariation. The top of head and thorax is dark green. One of the elytra is almost wholly fuscous, only a small space in the outer apical fourth being yellow; the other one has a broad, fu>seous sutural stripe extending from apex to base and along the latter to the humerus, where it is recurved. Otherwise it agrees with the common forms of the species and is therefore to be recorded only as a sport. XX^^II. PoLTMCECHUS Lee.
