The classical deposits of Senigallia, in the north-east of 

 Italy, also belong to the Miocene period. These deposits, so 

 famous for the quantity of animal and vegetable remains 

 detected therein, contain, says Signor Mas-alongo, numerous 

 impressions of insects. It was from these strata that Signor 

 Procaccini-Ricci obtained a considerable number of species, 

 which afterwards formed part of the collection of Signor Giuseppe- 

 ScarabelU di Imola. 



Signor Massalongo describes two fossil larvae of genus 

 Libelluhx, which he states that he found by chance in splitting 

 open some slabs of stone from this locality. He has named one 

 species Lihellula Eurynome and the other species Libellula Boris. 

 With this exception I have failed to meet with the description of 

 any fossil insects from Italian strata of this period. 

 Middle Miocene. 



To this period are referred the Marls of Eadaboj in Croatia 

 which have been productive of a great quantity of insect remains. 



Professor Unger was the first author who published (in 1839)- 

 on the fossil insects of this locality a ]\Iemoir of any importance. 

 This was followed, in 1843, by a paper by Von Charpentier (in the 

 Acta. Acad. Leop. Carrol). Since then Professor Heer has 

 thoroughly studied the fossil insect fauna of Eadaboj, in which 

 he has recognised a great number of tropical forms including some 

 gigantic Termites. 



The insects from this locality comprise the following : — 



42 species.

 The Coleo2)tera are rare, but the Ants are represented by 

 fifty-seven species, of one of which (Formica Occultata) Dr. Heer ■ 

 is said to have obtained 594 examples. Sir Charles LyeU observes
