Wow a blast from the past. A Micro Q decoupling capacitor was in fashion many decades ago for pin-and-wire breadboards that didn't have a ground plane. People habitually included these just in case as a extra insurance and to avoid wasting time with well-meaning but naive colleagues who insist on giving irrelavant advice such as "supply decoupling problem??" when you're trying to debug a design after first switch on.
Sometimes if there really WAS a 'decoupling problem' you might find these tacked ON TOP of an affected IC.

Are you sure? yes | no
Oh wow... for underneath dip ic's...
Who knew
Many thanks
Are you sure? yes | no
Bharbour is right. Here is the datasheet: http://pdf.dzsc.com/2008717/200807171457468171.pdf

I am going to say a high voltage (400v?) capacitor.
Are you sure? yes | no
Pretty sure it is a decoupling capacitor.
