male and female reproductive organs in the same individual, but 

 this point has been disputed and must be considered for the 

 present as subjudice. In the rase oi a few Braconid parasites, there 

 occurs the phenomenon of Polyembryony, in which a single egg 

 divides to give rise to several embryos. Finally, we may make a 

 brief reference to the phenomenon of Hypergamesis, found in some 

 iptera (e.g., the Bed-Bug, Clinocoris lectularius) in which the 

 greal mass of spermatozoa take no part in the actual work of 

 reproduction, which is accomplished bj relatively few ol the male 

 cells, but are stored up in the body of the female and serve as a 

 source of nutriment for the development of the eggs. But it maj 

 be added that the actual facts regarding most of these abnormal 

 methods of reproduction are still open to doubt.
