 Pinto, M. P. D., 1941, pp. 73-105. (Ceylonese 

 Calotermitidae, apterous and brachypter- 

 ous neoteinics developed from undifferen- 

 tiated nymphs in absence of functioning 

 dealated adults in colony, or in groups 

 of immature forms separated from pa- 

 rental nest. Under certain conditions 

 nymph can inhibit development of wing- 

 pads even after latter have attained con- 

 siderable size. Breeding experiments have 

 shown that neoteinics can survive without 

 assistance of immature forms and that 

 they do not necessarily breed true.)

 groups of reproductive and worker-sol- 

 dier individuals as claimed by Thompson 

 (1917, 1922). Eggs contain potentialities 

 for development into specific caste but 

 extrinsic factors as presence quartz crys-

 dling or feeding of young by workers 

 may modify the direction of develop- 

 ment.)
