SiEBOLD has investigated some hermaphrodite bees belonging 
to the Italian race, obtained from a Dzierzon hive at Constance. 
He found in many of them r combination of sexual characters, 
not only in external parts, but also in the generative organs. 
The mixture of external characters is manifested sometimes only 
in the anterior or posterior part of the body, sometimes in all 
parts of the body or only in a few organs. Some specimens 
present male and worker characters on the two sides of the body. 
The development of the internal organs is singularly correlated 
with these peculiarities of external organization. The sting, 
with its vesicle and gland, is well-developed in hermaphrodites 
with the abdomen of the worker j soft in those with the drone- 
abdomen. The seminal receptacle, when present, is empty. The 
ovaries contain no ova. In the hermaphrodites with the drone- 
abdomen the male sexual organs are well-developed, and the 
testes contain spermatozoids. Frequently both testicular and 
ovarian organs are present on each side, the epididymis and 
copulatory apparatus are well developed, and an imperfect poison- 
apparatus exists. In these cases the tubes contain spermato- 
zoids, but there are no ova in the ovaries. The hermaphrodites 
are thrown out of the hive by the workers as soon as they 
emerge, and speedily perish. Siebold ascribes the production of 
these hermaphrodites to an imperfect fecundation of the ovum.

Tegetmeier mentions an instance in which Bees, upon taking possession of a 
tenantless hive with empty combs, secreted a quantity of new wax, and with 
it fastened the combs securely to the wooden frames in which they had been 
inserted. Proc. Ent. Soc. 1864, pp. 28 and 32, 33.
