122 HOUSEHOLD INSECTS 



It is impossible to say whether they were fertile or not, 

 but it is reasonable to suppose that they were. We 

 obtained them by confining a dozen or more adult bugs in 

 a large vial, and on the second day we found eggs in abun- 

 dance. The eggs must have been formed in the females 

 under natural conditions in the bedsteads from which they 

 were taken, and very likely the bugs were fertilized there 

 before we collected the females.
