From the foregoing it will be seen that the two chief characters investigated, 

 namely, the jjresence or absence of the posterior ciliated epaulettes and the j)resence 

 or absence of the green jngment masses, are always inherited through the female 

 (text-fig. 10). It must be emphasized here that this rule was, during 1909-11, quite

uniform and invariable. In all our cultures the hybrid larvae obeyed the same law of 

 inheritance. 



With regard to the posterior ciliated epaulettes, in crosses in which E. miliaris 

 was the female parent, this character was never developed. When the eggs of 

 E. esculentiis or E. acutus were used, the posterior epaulettes were always present, 

 although their development was not so great as in the pure forms. 



Again, with regard to the green pigment masses, when E. miliaris was the female 

 parent they were always present in the hybrids, but when E. esculentus or E. acutus 

 was the female they were always absent. 



As stated above, the posterior pedicellaria is never present in E. miliaris, but is 

 usually, though not invariably, developed in E. esculentus and E. acutus. In the 

 hybrids it is not developed in crosses with E. miliaris $ , and is usually present in 

 crosses with E. esculentus $ and E. acutus $ .
