NEUEOPTEBA— TERMITINA.

and Schossnitz, as well as among modern types; while the other two prob- 

 ably fall into Eutermes, and are allied to, but considerably smaller than, 

 the species from Radoboj placed with many modern types in the same 

 genus. They are perhaps more nearly allied to, as they certainly agree 

 better in size with, the two species of Termes found living in the neighbor- 

 ing valley of the Fontaine qui Bouille. Calotermes, which has furnished 

 species from amber and the Rhenish basin, Terraopsis, which has more fos- 

 sil (amber) species than recent, and Termes proper, which is represented at 

 Oeningen and Radoboj and in amber and the Rhenish basin, all seem to be 

 wanting in the American Tertiaries. The composition of the white-ant fauna 

 of the ancient Florissant, to which locality the known American fossils are 

 confined, differs considerably from that of the localities known in the Eu- 

 ropean Tertiaries, but resembles that of Radoboj more closely than it does 

 any other, as will appear from the following table of representation:

Out of one hundred and iifty-three specimens of amber white ants ex- 

 amined by Hagen only a single larva, and no soldier, was found ; all other 

 fossil individuals have also been winged specimens; but it is worthy of 

 special remark that in the collection of twenty-six individuals from Floris- 

 sant one is a larva. The scarcity of such forms, whether in amber or 

 lacustrine deposits, is easily explained by the habit of life of these creatures. 



The very presence of so considerable a number of Termitina (twenty- 

 six specimens, six species') in the Florissant beds is indicative of a much 



' According to Hagen (Linn. Eiit., vol. Vi, p. 244) no locality in the world has yielded more than 

 nine species of living types; they so rarely number more than four, that he had formerly indicated 

 this as the limit, so far as known.
