VERMES. 
Schneider finds (37) that queen bees infested with Sphcerularia die in 
the beginning of June, and do not found a colony. On their death, the 
Sphaerularian embryos are set free ; after two ecdyses, they develop into 
males or females; during their free life, they take no food, and do not 
propagate ; they develop further on reaching the intestine of the bee 
larvae, and the time when the ySung imagines are set free is the same at 
which the larvae of the queen appear. 
Leuckart (30) finds that the so-called Anguillula stercoralis is a stage in 
the life-history of A. intestinalis.
