As there seems to have been no attempt, at least in this 

 •country, to determine the prolificacy of this insect, the following 

 may be of interest. May 31, 1898, .two heavy gravid females 

 were isolated, provided with plenty of food, and the eggs 

 removed and counted nearly every day. The results are tabu- 

 lated below.
