The Blue Beetle was marketed as a newspaper comic strip in the early 1940's. This strip was briefly drawn by Jack Kirby.

Little information about this strip seems to be available online or elsewhere. I was  able to find this one panel in Maurice Horn's The Encyclopedia of Comics.

During this era it was common for newspaper adventure strips to have two ongoing storylines. One story would be told in daily installments in brief black and white segments, while another story would be told in large full-color strips in the Sunday comics supplement. This gave the newspapers the option of only buying the daily or the weekly story, and many newspapers that had very large Sunday comics sections did the latter. In those times, a Sunday comic strip often filled an entire newspaper page, allowing much more complex stories than could be told in today's papers.

If you have access to newspapers from this era, you may be able to read this strip.
