Interim Head Coach, Mike Blair, will oversee a group captained by Edinburgh Rugby's Jamie Ritchie for games against England A, Romania and Georgia.
With eight Scottish players unavailable following their selection for the British & Irish Lions' own tour to South Africa the summer squad combines youth and experience and provides an opportunity for players two years out from a Rugby World Cup to demonstrate their international credentials.
The full group will convene on Tuesday 15 June to prepare for the England A fixture on Sunday 27 June, with a smaller squad then travelling to Romania and Georgia for the two Test matches on consecutive Saturdays, 10 & 17 July respectively.
Of the uncapped contingent, Luke Crosbie, Charlie Shiel (both Edinburgh Rugby) Rory Darge, Jamie Dobie, Rufus McLean, Ross Thompson, (all Glasgow Warriors) Josh Bayliss (Bath Rugby) and Ewan Ashman (Sale Sharks) have previously spent time in the Scotland set-up.
For others, namely centre/wing Sione Tuipulotu, second row Kiran McDonald, back three player Cole Forbes (all Glasgow Warriors), wing Jack Blain (Edinburgh Rugby), props Nick Auterac (Northampton Saints), Javan Sebastian (Scarlets) and Robin Hislop (Doncaster Knights), and second rows Cameron Henderson (Leicester Tigers) and Jamie Hodgson (Edinburgh Rugby) call-ups will represent their first taste of a senior international camp.
The squad retains experienced players, with no fewer than 20 previously representing Scotland.
Indeed, six players - Blair Kinghorn, Matt Scott, Adam Hastings, Scott Cummings, Simon Berghan and Jamie Ritchie - have earned at least 20 caps to date.
Interim Head Coach, Mike Blair, said: "We have selected a mix of genuine Test match experience and a number of players who have impressed in the recent past to warrant a place in a squad that will want to continue the positive progress we have built up on and off the pitch in recent months.
"England A, Romania and Georgia will each pose different and tough challenges and we will have to be operating at our best to enjoy success, continuing on from some promising performances during the 2021 Guinness Six Nations.
"With the next Rugby World Cup two years away this period gives us an opportunity to increase our depth in key positions and work with players who can put up their hands for international selection this summer, and beyond."
