corum^ hortorum^ terrestt'is, and laindarius) as also the Hive-Bee (Apts melli- 
Jica) as noxious to man on account of their stings. He describes the appear- 
ance and habits of the above-mentioned species. 
J. Lowe (Ent. Trans. 3rd ser. v. pp. 647-660) publishes some observations, 
on the theory of the reproduction of the Honey-Bee, propounded by Dzierzon 
and supported by Siebold. He states that queens of the Ligurian and Egyp- 
tian races {Aph ligmtica and /«scm^a) when fertilized by drones of the com- 
mon English type {A. mellijicd) produced drones which betrayed their mixed 
parentage in their characters, as ought not to have been the case if the drone- 
eggs are deposited without fecundation, as supposed by Dzierzon. 
11. Landois (Zcits. f. wiss. Zool. xvii. pp. 376-379, and Oomptes Bendus, 
Ixiv. pp. 222-224) records some experiments on the transfer of eggs from 
worker- to drone-cells and vice versa. The insects produced were workers or 
drones according to the cells in which they were reared, whence the author 
concludes that the difference of sex in Bees depends solely on their nou- 
rishment. 
Tasciienberg (Zeitschr. ges. Naturw. xxix. p. 87) states that the life of a 
worker Bee during the busiest season is only about six weeks.
