I think this may be right.
Others have mentioned looking at how the other names are written on the same census form - and this is always the first step.
Unfortunately, in this case, it looks like different people entered their own details. There appears to be three different hands who have completed this census (as well as the enumerator).
There is Mr & Mrs Simpson done in one hand. There is then people described as their son and daughter (but in another hand, I would guess that was the enumerator, it has been added that they are the step-son and granddaughter).
Then there is Ricarto in another hand. It looks like Ricarto wrote his own entry, well, at least his name and place of birth. It looks like his occupation and employer may have been added by the step-son and the address of his employer by the enumerator.
His surname does look like Bianco, but it may also be Biane.
[EDIT]
Although,as @LemonCookie8 said, the first name could equally be Quinto
