Bumps

Often they are described as tubercles/tuberculate (larger structures) or granules/granulate (smaller structures). There may be other descriptors that aren't popping into my head at the moment.

Thanks Brad

I'm not overly fond of the word tubercles (not sure why it bugs me). Do you know what is considered large or small? The beetle above being granulate? The beetle below being tuberculate?

Both tuberculate

though yours may be pushing granulate, but descriptors like these are often subjective...

I would, in general, call bumps readily noticeable to the naked eye tubercles and those that are smaller, usually requiring some magnification to see, granules.

(Referring to the Dictionary of Entomology by Torre-Bueno, I am seeing granule defined as "a little grain or a minute grain-like elevation" and tubercle defined as "a little solid pimple or small button.")
