). This disjunct record seems questionable. If the original range of this species extended from northeastern Texas south to the coastal bend, it seems plausible that early beetle collectors in Texas who either lived or travelled through these areas in the late 1800s and early 1900s (E.A. Schwarz, H.S. Barber, J.D. Mitchell) would likely have encountered and saved specimens of this large conspicuous beetle. Horace Burke, Professor Emeritus and entomological historian (Department of Entomology, Texas A&amp;M University) states the following regarding C.T.
