Biology:
Browne, 1961: This species bears a general resemblance to X. punctatissimus, but is considerably smaller. It has been found infesting stems of cut trees of various sizes, from a pole of 3 cm diameter up to the largest logs. Because of the slightly flattened shape of the adult beetle, its tunnels tend to be elliptical rather than circular in cross section. Adults have been found boring short tunnels directly into the wood, the tunnels tend to take the form of irregular cavities, widest at the inner end, where the eggs are laid.
