1917] Notes on Coccinellid Genus Adalia Mulsant 297 



In this case every one of the forms under consideration 

 appeared from the eggs of a single female, but hybrids of 

 bipunctata were discovered only with annectans and hiimeralis. 



On the 25th of May an egg patch was obtained from another 

 annectans female (Figure 21), taken out of doors already 

 fertilized. Though, for 5 days before laying the eggs, it had 

 been mated with a bipunctata male, the one used in Figure 

 1, 2, 3, and 5, no trace of bipunctata appeared in the progeny. 

 Thirteen beetles matured, 3 annectans, 4 normal melanopleiira 

 with lateral dot, 3 melanopleura with white area, and 3 colo- 

 radensis with a lateral dot placed more posteriorly than the

lateral dot of the other forms. In the second generation from 

 the color adensis cage, 2 beetles were reared and they were 

 both coloradensis with the posterior lateral dot. 



Judging from this case together with the similar results 

 with the coloradensis progeny of the former annectans female, 

 it is evident that coloradensis often possess a lateral dot, more 

 posteriorly placed than in other forms, instead of the broad 

 white area as given m the former paper of 1911. Both these 

 patterns are mentioned in the original description by Casey. 

 The above-mentioned lateral dot seems in this case to have 

 bred true, but considered with the case in Figure 20 it can 

 hardly be considered more than a fluctuating variation, since 

 in that case a pair of coloradensis humeralis hybrids, one with 

 the dot and one with the white area produced progeny both 

 with and without the dot.
