1911] Heredity in Adalia 297 



In the case of the pattern of reddish spots on the elytra of 

 a u necta ns Figure B, Plate XIX , it seemed as though there might be 

 segregation in some cases at least, and that the absence of the 

 character was dominant to its presence. In the series in Figure 

 2, Plate XX, it shows faintly in the mother (the dimness may be 

 due to fading after death as this character was not recorded 

 during life) and it was plainly evident in the mother and a 

 brother of this beetle, in fact in all of the individuals of this strain 

 that have been preserved. It shows in none of the 30 progeny 

 of this beetle, but this absence may be explained as due to 

 the males, which being lost, can not be examined as to their 

 possession of the character. 



In the series in Figure 3 where the mother does not show the 

 marking but carries two strains of annectans, it appeared in 

 five-sixths of the beetles to a greater or less degree. As the 

 male in this case was humeralis both of these strains must have 

 come from the mother and its absence in her development 

 would seem to signify the dominance of the absence of the 

 character over its presence. The proportion, however, found 

 in the progeny seems rather puzzling unless the humeralis 

 character from the male could have had any influence in the 

 proportion, which seems unlikely. 



In the series in Figure 4, Plate XXI, it appeared in all of the 

 27 annectans progeny. The mother, being melanopleura of 

 course does not show it. In the series in Figure .3, Plate XXI, 

 some show it and some do not. The exact number in each case 

 can not be determined as some of the beetles have developed so 

 much of the red color in their elytra during hibernation that it 

 is impossible to tell with certainty whether they possess the 

 character or not. The mother being melanopleura of course 

 does not show the character. The fact that some clearly show 

 its presence and others just as clearly show its absence when 

 they are all from one strain of annectans seems to be evidence 

 against segregation in this case. 



In the pronota curves in Figure 7, Plate XXII, the matter is a 

 little more complex as there are both annectans and melanopleura 

 to be represented for each female except one, Figure 2, Plate XX. 

 As the curves for these two forms even when from the same 

 parents were different in every case not only in the position of 

 the apex but also in range and sometimes very different, it 

 would seem that each strain keeps distinct ; that is, the pronotal 

 characters of annectans do not mix with those of melanopleura.
