THE PROTOZOA OF TERMITES 41 



classified at present. There is much overlapping, and resemblances 

 are sometimes greater between the flagellates of species in sepa- 

 rate genera than between those in the same genus. This probably 

 indicates the need of reclassification of these termites. 



5. The genus Hodotcrnics contains a fauna related on the one 

 hand to that of the kalotermitin^ and on the other to that of the 

 RHiNOTERMiTiD^. In Hodotcnucs, there are representatives of the 

 DEVESCOviNiD^, CALONYMPHiD^, and jcENiiD.^, which are well 

 developed in the kalotermitin^. Also there are species of Spiro- 

 trichonynipha, Holoniasfigofcs, and Holomastigotoides, which are 

 characteristic of the rhinotermitid^, although Spirotricho- 

 nyinpha is found also in the kalotermitin^. 



6. The rhinotermitid^ may be divided according to intestinal 

 faunas into two markedly different groups, the first containing 

 the genera Hcfcrotcnncs (-Lcucotcnncs). Coptotermes, Prorhino- 

 tcrmcs, Termitogctou and Rhinotcrmcs and the second only the 

 genus Rchculitcnncs. The flagellates Holomastigotoides, Spiro- 

 trichonympJia, and Pscudotrichonyuipha occur in the first group; 

 Holomustigotcs, Tnchonympha, S pirotrichonympha , Micro jwnia 

 and the pyrsonymphid^ in the other. 



The termites of the genera Hetcrotcrmcs and Rcticiditenncs 

 were formerly placed in one genus and until recently in subgenera 

 of one genus. However, their flagellate faunas are much more dis- 

 tinct than are those of Hctcrotcnnes, Coptotermes and the other 

 genera. 



Representative material of most of the genera of flagellates in 

 termites is obtainable within the borders of the United States. 

 Reticulitermcs occurs in most parts of the country. In the Pacific 

 Coast States the large termites of the genus Termopsis are com- 

 mon, and KALOTERMiTiN^ {Kaloternies, Cryptotermes and Neo- 

 termes) have been found in Georgia, Florida, Texas, Arizona and 

 California. A species of Prorhinotermes which occurs in the West 

 Indies has been found in southern Florida, and Heterotcrmes 

 aureus has spread from Mexico into desert parts of southern Cali- 

 fornia. The termites of the United States have been described by 

 Banks and Snyder (1919). 



Cleveland (1928) and Beckwith and Light (1927) have dis- 

 cussed the maintenance of termites in the laboratory. Filter paper 

 may be given as food, and success in keeping the colonies depends 

 on the proper amount of moisture. Some termites require very
