The second type includes those eggs which show a slow 

 development during anatrepsis, iniluenced to a certain degree 

 by rise in temperature, as in the cases of Locusta migratoria"' , 

 Tmethis pulchripennis asiaticus^ and Calliptamus palaestinensis^. 

 In Dociostaurus^ the influence of temperature at this stage is not 

 significant and this period may last up to five months. 



The eggs during this period are not affected by addition of 

 water in Calliptamus and Locusta, but are spoiled in the case of 

 Dociostaurus and Tmethis. 



The third type occurs at the end of anatrepsis and includes all 

 forms of diapause which cannot be broken by changes of 

 humidity or temperature. During this period the embryo is
