You need to be careful because erase() will invalidate existing iterators. However, it will return a new valid iterator you can use:

for ( it = Entities.begin(); it != Entities.end(); ) {
   if( (*it)->getXPos() > 1.5f ) {
      delete * it;  
      it = Entities.erase(it);
   }
   else {
      ++it;
   }
}
