Not sure how I am confusing you.  And no it should not delete a hole.  I've stated I want to DELETE X amount of measures and all content within those measures.  I don't want to leave a hole of empty measures.  I want the measures deleted. 
 
Not sure how much more clearer I can explain it.

There is a checkbox in the Delete Special dialog box which says "Delete Hole"
You should always tick this if, as in your case, you want the data you are keeping to "slide to the left" after delete.
 
But as mettelus has pointed out, it's a bit buggy and in order to work properly there MUST be data in the hole prior to deleting it.

No matter what I try I cannot get rid of the measures.  With data in the measures on all the tracks I've tried Delete, Delete Special.  I've tried with and without Delete Hole checked and all I end up with are blank measures I cannot delete.  How the heck does someone do this?  I want to delete the measures outlined in yellow!  This is crazy!

like people have said, delete hole can be a little buggy. when i tried it out yesterday before posting, and again just now, i found that if it is audio tracks it seems to work fine, as expected, you delete the section with delete hole checked, it is deleted and the later parts slide over, but if it is midi data alone (as it seems is your case), or a selection of audio and midi data, the tracks with midi data will just delete the selection but leave the hole as you are experiencing, the audio tracks however will (should) work as expected. you can fix this easily enough by manual means and a little extra effort, although you shouldn't have to

This is one of the few really really annoying things about Sonar for me. You can work around it by lassoing stuff and manually sliding it if you're lucky and your project isn't too complex, but it's a pain. We're all eagerly awaiting the announced "ripple edit" feature for Sonar Platinum but there's no ETA on it.

Your first step is to select all tracks and cut the clips somewhere in the region without midi events you want to delete. If your song doesn't have any tempo changes, measure changes, or markers, you can select the clips to the right and drag them to the left.
 
If you need to move tempo changes etc as well, there are two options:
1. Select all, then press control to unselect the clips on the left. Cut the selected and paste it at measure 75.
2. Create a new clip with one long midi note from measure 75 to 91. Select the range from 75 to 91 on all tracks and use Delete Special with close hole active. (In the current version of Sonar, you need to copy the clip with the long note to all tracks, but I think this is not necessary in X3.)

So, I am obviously really really stupid!  or I am totally missing something.  I've selected all the tracks to the right of the empty measures and click on the timeline to move/drag the tracks over and .... nothing moves!

You don't click on the timeline to move/drag tracks, you click and drag directly on the tracks.
now maybe you can see why I said you were confusing me.
Im out.
 
Good luck.

If you are saying that once ALL the tracks I want to move are highlighted I should be able to click on any one of the tracks to move them all?  Is that correct?  Because that doesn't work.

if you select all the clips to the right of the space you cut out, clips, not really the tracks as such, with all them selected you should just be able to left click and drag

Unless any of them have their position locked, I think. But usually that is something you would have done yourself (locking position).
