The species "was subsequently described and figured by Dr. 

 Boisduval. Mr. Butler has referred it to tlie Safyridce, and has 

 described and figured the insect in his " Lepidoptera Exotica." 



The second butterfly from these formations is described for 

 the first time by Mr. Scudder as Lethites Ile>jiiesii. It does not, in 

 his opinion, belong to any existing European genus, and he 

 mentions Manioln Hermione as its nearest ally among living 

 European types. This fossil was found by Mr. Scudder in the 

 Museum at Marseilles, and named by him after Dr. Reynes, 

 director of that establishment. It appears to have been previously 

 overlooked. 



The third l>utterfly from Aix is described and figured by 

 Scudder as Collates Proserpiii'i. It is in the collection of Count 

 Saporta. It appears to have been discovered in the strata 

 immediately beneath the caleareou-; marls of the gypsum quarries, 

 and is, therefore, the oldest butterfly from the Tertiary formations. 



The fourth insect of this order from the3e deposits is de- 

 scribed by Professor Heer as '•' Thaltcs Ramin'uma," who observes 

 of it, " closely allied to the genus Thaii, which belongs to the 

 Mediterranean fauna." It is in the collection of Professor Heer, 

 and has been also described and figured by Mr. Scudder. 



The remains of the fifth and last butterfly from the tertiaries 

 of Aix, or, indeed, from any tertiary formation, consists of a 

 single forewing, which Mr. Scudder refers to some species of a 

 genus belonging to the Astyci. Mr. Scudder describes the species 

 as Pamphiletes Abdiia. The remains are in the Marseilles 

 Museum. 



It will be noticed that the remains of all the fossil butterflies 

 at present described have been found at Radoboj, Eott, and Aix, 

 M belonging to the tertiary formations ; that the remains of 

 three species belong to the Mayencian, or lower portion of the 

 Middle Miocene, the remains of one species to the lignite beds of 

 Kott, belonging to the Aquitanian or upper part of the lower 

 Miocene, and the remains of the other five species from the
