Why don't you just delete those kernels in Synaptic?  It will take care
of removing the extra GRUB entries for you.

https://wiki.ubuntu.com/Grub2#Removing%20Entries%20from%20Grub%202

"Kernels removed by Synaptic will automatically update grub.cfg and no
user action is required."

1) use "uname -a" to find out which kernel you are currently running
(e.g. "Linux shoggoth 2.6.32-19-generic...")

2) open Synaptic (System / Administration / Synaptic Package Manager)

3) ctrl-F to search for "-18", "-17"... (older kernels)

4) for each set of search results, delete the entries starting with
"linux-" and including the version to be deleted (e.g.
"linux-headers-2.6.32-18")

5) reboot and the extra menu entries will be gone from GRUB
