Essentially the same as the preceding. The quotation given above is found on p. 24 of the Jahrbuch, p. 72 of the Journal. “Schmetterlinge” is everywhere translated Butterflies instead of Lepidoptera. Aix in Provence is nearly always given as Aix-la-Chapelle. 1851. LEFEBVRE. Observations relatives à l’empreinte d’un Lépidoptère fossile (_Cyllo sepulta_) du docteur Boisduval. Ann. Soc. Ent. France [2], IX, 71-88, pl. 3, No. II. Criticises at length the opinion of Dr. Boisduval on the systematic position and structure of _Neorinopis sepulta_, maintaining that the fore and not the hind wing was furnished with a tail, and while confessing his inability to decide upon its relationship, inclines to the opinion that the insect was more nearly allied to Vanessa. His studies were wholly taken from the plate published by Boisduval. 1851. BOISDUVAL. Quelques mots de réponse à M. Alex. Lefebvre sur ses observations relatives à la _Cyllo sepulta_. Ann. Soc. Ent. France [2], IX, Bull. 96-98. Defends his views against the criticisms of Lefebvre. 1852. GIEBEL. Deutschland’s Petrefacten. p. 644. 8vo. Leipzig. Catalogues the three butterflies described by Heer from Radoboj. 1854. WESTWOOD. Contributions to Fossil Entomology. Quart. Journ. Geol. Soc. Lond., X, 378-96, pl. 14-18. Represents on pl. 17, fig. 17, and pl. 18, fig. 27, two fragments of wings, which he considers as belonging to butterflies, and to which, on pp. 395-6, in the explanation of the plates, he gives the names of _Cyllonium Boisduvalianum_ and _C. Hewitsonianum_. 1854. PICTET. Traite de Palæontologie, II, pp. 392-393, pl. 40. 8vo. Paris. Gives a brief account of the fossil butterflies then known, and reproduces excellently the figures of _Neorinopis sepulta_, and _Mylothrites Pluto_ given by Boisduval and Heer. 1856. GIEBEL. Fauna der Vorwelt, II. pp. 185-7. 8vo. Leipzig. Gives a similar but fuller account of the butterflies described by Heer and a brief notice of others. 1856. GIEBEL. Geologische Uebersicht der vorweltlichen Insekten. Zeitschr. gesammt. Naturw., VIII, pp. 174-188. Gives lists of Lepidoptera summarized from his previous work. 1856. HEER. Ueber die fossilen Insekten von Aix in der Provence. Vierteljahrsschr. naturf. Gesellsch. Zurich, I, 1-40. Simply mentions in his introductory remarks the occurrence of _Neorinopis sepulta_ at Aix, and says that most of the insects from this locality present a Mediterranean aspect. 1858. HEER.
