NATURAL SCIENCES OF PHILADELPHIA. 321 SYNONYMICAL REMARKS UPON NORTH AMERICAN COLEOPTERA. BY JOHN L. LE CONTE, M.D. In the Annals and Magazine of Natural History, November, 18t0, I published some notes made during a rapid examination of various collections in London and Paris ; subsequent opportuni-ties enabled me to make some additional notes, and more careful studies of the species which I had not time to investigate on my first visits. These are contained in the present paper, with such corrections of my former notes as seem to be necessary at the pre-sent time. 1. CiciNDELA LONGiLABRis Say. A Specimen jabelled Bermuda in the Oxford Museum. 2. C JNIagdalen^. Marked like cinctipennis Lee, but the pro-thorax is more rugose, the elytra more strongly punctured, and distinctly serrate at tip ; in addition to the usual markings, dilated and connected at the margin, there is a basal white spot (as in macra), and a subsutural white vitta. Oxford Museum; found in turpentine barrels brought to London, supposed to be from North Carolina. I have named this species in friendly recollection of Magdalen College, Oxford, the genial influence of which has been experi-enced by man}' scientific nilgrims to the Universit3^ 3. C. lacerata Chaud. n-om Louisiana, scarcely differs from the Mexican C. hamata. 4. C. PAMPHiLA Chaud. An undescribed species from Texas, of stout form, allied to pallifera. Elytra with the dark spaces strongl}' punctured, tip very finely almost obso-letely serrate ; last ventral segment 9 longitudinall}' im-pressed and marked with white spots. 5. Elaphrus americanus Dej. The type in the col-lection of Baron Chaudoir is evidently the common species afterwards described by me as punctatissimus. There are many other synonyms for the various races which occur in its wide distribution from the Atlantic to the Pacific, and northwards nearly to the Arctic circle. 6. NoTioPHiLUS aquaticusX Kirb}'. The type in the British Museum does not resemble the European species ; it is more brassy
