REVISION" OF NEARCTIC TERMITES. 7 



At Florissant 26 individuals of termites have been found, repre- 

 senting six species, three in the genus Parotermes, one in the genus 

 Hodotermes, and two species of " Eutermes''; one individual is a 

 ''larva.' 



According to Hagen (1858) no locality in the world has jdelded 

 more than nine species of living types of termites; they rarely num- 

 ber more than four. Yet in Washington city, not far south of the 

 Mason-Dixon line, three species of Reticulitermes occur. In the 

 Santa Catalina Mountains, Arizona, at least 12 species of termites 

 occur. However, these insects are found more frequently in the 

 Southern States, especially the GuK and Southwestern States, where 

 all of the 10 genera found in North America are represented. 



In America, north of Mexico, 19 known and 17 new termite species 

 and one new variety have been found, representing 2 families, 4 

 subfamilies, and 10 genera. Two of these genera have not previously 

 been recorded in the United States, 



These species are distributed in the genera as follows: Termopsis, 

 3 ; Ralotermes, 9 ; Neotermes, 1 ; Cryptotermes, 3 ; Prorhinotermes, 1 ; 

 Reticulitermes, 9 and 2 varieties ; Amitermes, 6 ; Anoplotermes, 1 ; Con- 

 strictotermes, 2; Nasutitermes, 1. 



By subfamilies : Termopsinae, 3; Kalotermitinae, 13; Rhinotermi- 

 tinae, 10 and 2 varieties; Termitinae, 10. 



By families: Kalotermitidae, 16; Termitidae, 20 and 2 varieties. 



The following table will give an idea of the relative abundance of 

 termites in the various States : 



DISTRIBUTION BY STATES, 



In Texas four species and one variety of Reticulitermes, occur; 

 Virginia, Maryland, Florida, and the District of Columbia have at 

 least three species of Reticulitermes, and many States have two. 



Of the 13 species of Kalotermitinae 7 occur in Florida, 4 in Texas, 

 and 3 in Arizona. Of the 9 species of Termitinae, none occur in Flor- 

 ida, 6 occur in Texas, and 4 in Arizona, North of Georgia and east of 

 Nevada (excluding the southwest) there is but one genus — namely, 

 Reticulitermes. This genus is evidently of northern origin; several 

 occur in the Palarctic region ; a few of ours spread to northern Mexico, 

 but none in South America, Termitinae do not occur m Europe, but 

 are abundant in the Tropics of the Old and New World, The species
