I have always just called them semi-recessed communications terminal enclosures.
But I don't know if anybody else does.
If I find one that has TV or CATV or TEL embossed in the cover, I make it more specific.
Depends on what's in the boxes. If it's Telecom, then it's a demarcation box. If it's electrical, I'd call the top one a recessed Hoffman box and the bottom one a recessed gutter.
