This is a ventral view of the head section of an Hide Beetle, probably genus Trox.
It is about 1 cm long and a yellow tan color. What interested me was the handlike antennae retracted under the head.

The blue background was accomplished by sliding a paper house paint chip sample under the slide, freely available at local hardware stores.
