Where can I find the Xfce-dusk/Xfce-stellar themes to install in Xubuntu? [SOLVED]

Hello Xubuntuites!

I'm running Xubuntu 14.04.3, and, as usual, it's running flawlessly. So what I'd like to do now, since Xubuntu is running so well, is add the Xfce-dusk and Xfce-stellar styles, or themes, to my themes lineup. I'm sure there a way do this using Synaptic, but I'm having no luck finding where to go within Synaptic in order to do so. Could someone who is familiar with both Xubuntu and Synaptic be nice enough to tell me what I need to install from Synaptic in order to have these two themes for myself?

Thank you,

They are provided by the package gtk3-engines-xfce.

Thank you, Dennis N.

Your suggestion pointed me in the right direction. I guess these themes must be older than the gtk3 engines. I found them by dropping one version down to gtk2-engines-xfce. Problem solved!

Thank you,
