Difference between cons and dot

Am adding an elemnt to an alist using either the cons or dot method.
Have noticed that with cons I do not need to call list 

Thusly 

(push (cons kfrz lnum) tema-lugar)

rather than

(push '(cons kfrz lnum) tema-lugar)

But with the dot method I have to use 

(push '(kfrz . lnum) tema-lugar)

and not 

(push (kfrz . lnum) tema-lugar)

What is the reason for this difference ?
