Scudder, Samuel H. Fossil Butterflies. Mem. Amer. Assoc, vol. i. 

 pp. xi, 99 ; 3 pis. 



An account of all the known remains of fossil Lepidoptera. The 

 author agrees with Mr. Butler in regarding Neorinopsis sep^dta as 

 belonging to the Satyridae. The new genus Lethites is established for 

 the reception of the L. (Satyrites) Beynesi from the Tertiaries of Aix. 

 The Vanessa atavina of Heer (the Sphinx atava of Charpentier) is re- 

 ferred to the genus Engonia. The new genus Mylothrites is founded 

 for the famous Vanessa Pluto (Heer), and the genus Coliates for a new 

 species (C. Proserpina) from the Tertiaries of Aix. Heer's Pierites 

 Freyeri is referred to Pontia ; and his MS. genus Thaites, with the 

 single species T. ruminiana, is described. The new genus Thanatites 

 is established for Yon Hey den's Vanessa vetida ; and a new butterfly 

 from the Tertiaries of Aix is described under the name of Pamphilites 

 (n. gen.) abdita. The author discusses the comparative age of fossil 

 butterflies, the probable food-plants of Tertiary caterpillars, the present 

 distribution of butterflies most nearly allied to the fossil forms, and 

 the afiinities of certain fossil insects which have been referred to butter- 

 ~ flies. The Cyllonium Boisduvalianum and C. Hewitsonianum of West- 

 wood, from the Purbeck Beds, are thought not to be Lepidopterous, but
