Enaphalodes simpiicicollis. Dark brown, elytra somewhat 

 paler from a short pubescence; prothorax subglobular, minutely 

 granulate ; dorsal line slightly impressed posteriorly, a lateral ob- 

 solete impression before the middle towards the exterior margin ; 

 elytra sparsely and deeply punctured, bi-spinose at tip. 11 1. long. 

 Georgia. Distinguished from E. lecontei, Dejean, (pulverulentum, 

 Fabr., hitherto considered an Elaphidion by me) in having a smaller 

 prothorax, a darker color, and in being less. For the opportunity 

 to describe this and the next species of Longicornia, I am indebted 

 to the kindness of my friend Dr. J. L. Le Conte, in whose cabinet 

 they are. 



Stentjra? cyanea. Brilliant metallic blue with greenish re- 

 flexions : front impressed, antennas, mandibles, labrum, terminal 

 joint of palpi, and scutel, black ; elytra scabrous with confluent 

 punctures ; femora rufous, apex and extreme base, with the tibiae 

 and tarsi, blackish. 6 1. long. Lake Superior. 



Ploiaria maculata. Drown, superior wings pale grey with 

 whitish reticulations, and maculate with brown, darkest towards the 

 base, where there is a long conspicuous triangle with its apex ex- 

 tending to the base ; anterior edge of the wing with a single series 

 of spots, apex with a semicircle of large ones. 2. 1. long. Penn- 

 sylvania, in July. 



The only specimen of this well marked species is imperfect, and 

 although taken several years ago, a second individual has not been 

 seen.

Notice of the discovery of a Cranium of the Zeuqlodon. 

 By M. Tuomey, State Geologist of South Carolina. 



Almost every day adds something to our knowledge of those 

 remarkable forms, which in the revolutions of time have passed 

 out of existence. In 18 , Dr. Harlan described and figured in 

 the Transactions of the Geological Society of Pennsylvania, some 

 fossil bones from Alabama, consisting of portions of the upper and 

 lower maxillae of an animal under the name of " Basilosaurus," 

 from an impression that they belonged to a gigantic Saurian. An 

 examination of the teeth, however, satisfied Professor Owen that 

 these remains belonged to a Cetacean, to which he has given the 

 name " Zeuqlodon." 



The first description of an entire tooth of this animal, was given 

 by Mr. Buckley, in a concise account of the discovery of a consi- 

 derable portion of the skeleton, published in the American Journal 

 of Science in 1843. In 1845, Dr. K. W, Gibbes, of South Carolina, 

 published in the Proceedings of the Academy of Natural Sciences
