have to do with a gradual contraction of borders into spot-marking. 
The spots certainly increase in area while developing, and if we are 
to regard the occurrence of spots as a recapitulatory character this 
fact would seem to support Professor Weismann’s theory. If, however, 
they are reversionary, which now seems to me more probable, as they 
do not occur in all the individuals of a species, the increase in area 
would not have the same importance. The number of larve reared 
by me was, however, too limited to draw conclusions from safely, and 
had I had more individuals under observation, some might have 
presented different appearances.
