134 PROCEEDINGS OP THE AMERICAN ACADEMY 



The additions to the tertiary Termite-fauna here made are in en- 

 tire keeping witli these statistics ; six species are described, of wliich 

 four belong to the first, and two to the second section, raising the num- 

 ber of tertiary species to twenty-two, or about one fourth the number 

 of recent species. 



Of these six species, three belong to a new extinct genus, appar- 

 ently ijeculiar to America, but possibly including some of the species 

 from the European tertiaries ; another is referred doubtfully, from 

 want of sudicient data, to Hodotermes, which has yielded species from 

 Radoboj, Oeningen, and Schossnitz, as well as among modern types ; 

 while the other two probably 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 neighboring valley of the Fontaine qui 

 Bouille. Calotermes, which has furnished species from amber and 

 the Rhenish basin, Termopsis, which has more fossil (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 European 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 fifty-three specimens of amber white ants 

 examined l\y TTagen, only a single larva and no soldier was found ; all 

 other fossil individuals have ali^o been winged specimens; but it is 

 worthy of special remark, that in the collection of twenty-six indi-
