 fiauicollis.)

 hibition, Kalotermes flavicoUis; when

 Marcus, H., 1948, pp. 23-27. (Genetic basis 

 of polymorphism and suppression of sex- 

 uality. Polymorphy present in common 

 "Nasutus" sp. even in egg; horn soldiers 

 visible at very early stages, represents 

 a mutation. As soldiers sometimes lay 

 eggs, crossing with normal forms might 

 give hetcrozygotic spermatozoids. Origin 

 polymorphy a mating between Terries 

 and "Nasutus," resulting in a poly- 

 morphic heterozygotic termite, with re- 

 cessive horn, from which would result, 

 in Mendelian proportions, i sexual ter- 

 mite, 2 workers in which castration had 

 occurred, and i "Nasutus" soldier in 

 which castration had occurred.) 



19493, pp. 97-101. (Polymorphism of Nasu- 

 titermes chaquimayensis, Bolivia; classes 

 of Nasutitcrmes and queen of Rhino-

 crossing of this female with a hornless 

 male could produce all existent forms of 

 polymorphism, according to laws of Men- 



del in connection with arbitrary castra- 

 tion.) 



Miller, E. M., 1942, pp. 1-27. (Caste dif- 

 ferentiation Prorhinotermes simplex, Flor- 

 ida, extrinsic (inhibition theory), nymphs

 wing pads. No permanent well-defined 

 worker caste.) 



MoNTALENTi, G., 1927, pp. 529-532. (Italy, 

 Caloterjnes flavicoUis colonies kept alive 

 for comparatively long time on diet solu- 

 ble carbohydrates. After 3 to 4 days 

 notable diminution in number of Joenie, 

 Mesojoenie of caecum, after 10 days com- 

 pletely disappeared; caecum became re- 

 duced, other flagellates diminished in 

 numbers. Does not prove that starving 

 Protozoa without depriving termites of 

 food is equivalent to nutrition neoteinics 

 receive in nature.) 

 1929, pp. 108-128. (Termes htcifugus, Italy,
