Anastatus semiflavidus 
377 
449 days and a minimum of 226 days to complete their life cycle, the 
average being 380 days. (See Tables I and II for a record of two of 
these cages.) From a series of cages started in October, 1915, a total of 
40 adults were reared. These adults required a maximum of 346 days 
and a minimum of 238 days to complete their life cycle, the average being 
266 days. From a series of stock cages started the last week in Septem¬ 
ber, 1914, adults were reared from the first week in the following May 
until March, 1917, a minimum of 7 months and a maximum of 30 months. 
It is evident that this prolonged life cycle was not due to the artificial 
cage conditions because adults emerged from 1- and 2-year-old eggs 
collected in the field.
