Apterous is correct.
The things looking like scales made me wonder, but I did look from many angles and no wings extending over the abdomen, and no longitudinal medial line marking the meeting of the wings. Also, not a single vein, so my conclusion was larva, or apterous species.
Now I get to take a look at his relatives!

Thanks, Diane! I was just reading the comics at the
kitchen table when this bug appeared. I got my trusty camera, and the rest is history.
I did preserve it. Hence the PA-11 (Preserved in Alcohol specimen #11) in the title of my submition.
But do you see what I mean by clown nose? It has an almost spherical projection below and between the eyes, and above the mouth. And it has hairs on it!
