The correct reflexive pronoun is "themselves" -- the plural form of himself or herself (and in some cases, itself and oneself). The term 'theirselves' is a dialectic artifact (as is 'hisself' ) and is not formally correct.
The pronoun theirs and the adjective their are both possessive, and normally would have no 'self' form.
The reflexive pronouns are:
myself
yourself
himself
herself
itself
(oneself)
ourselves
yourselves
themselves
*majestic plural ourself
*gender neutral singular themself
The phrase "by themselves" means done on their own, without others.
There is no word 'theirselves' in the English languages. Themselves is a word.
