Wherever it occurs it is always confinedto the female sex, or (as in the case of some social insects) to the neuters, which are unde- veloped females. When it is not accompanied by a poison - reservoir it is used * Some further researches of value on the stings of Wasps and with copious illustrations, will be found in Hardwicke's Science for 1868, p. 148, by Dr. Mills, p. 205, by " S.
