408 ARACHNID A, MYRIAPODA, AND INSECTA. 



marine in origin, insects are rarely found. We meet, how- 

 ever, with remains of Orthoptera, Hemiptera, Neuroptera, and 

 Lepidoptem ; the most remarkable form of the last of these 

 orders being the Neorinopsis sepulta of the Aix-la-Chapelle 

 Sandstones (Upper Cretaceous ?), a Butterfly belonging to 

 the family of the Satyridce. 



In the early part of the Tertiary period little is yet 

 known of the Insects, but a vast number of fossil forms 

 have been preserved to us in deposits of Miocene and 

 Pliocene age. It would be quite hopeless to attempt to 

 give any detailed account of these here, but we meet during 

 these periods with representatives of all the existing orders 

 of Insects, with the exception of the Aptera, many of the 

 forms being closely allied to types now in existence. Even 

 the fragile and delicate Butterflies are fairly represented ; 

 one of the most celebrated examples being the Mylothrites 

 (Vanessa} Phdo of the Lower Miocene Marlstone of Eadaboj 

 in Croatia, which has been variously referred to the Nymph- 

 alince and the Pierince. Amber, a resin of Post-Tertiary 

 date, has, lastly, yielded a great number of insects, among 

 which are the only undoubted examples of any order of the 

 Apterous Insects (Thysanura).
