for which will be explained in the next chapter. 
If a queen is noticed on her return after mating 
with a drone, it will be seen that she carries 
the unmistakable signs of impregnation, by portions 
of the drone organ remaining attached. This was 
first observed and recognised by Janscha (73), and 
also later by Huber (68), in 1791, as portions of the 
male organ. Their observations were confirmed by 
Siebold {Bienenzeitung^ 1854, p. 227), to whom Ber- 
lepsch sent a specimen, and who made a careful 
microscopical examination.
