✦ Synopsis

The chromosomes of a Japanese endemic weevil, Callirhopalus (= Pseudocneorhinus) bifasciatus Roelofs, were studied from several localities in Japan. All specimens were tetraploid and no males were found in any locality. The results indicate that the species reproduces parthenogenetically.
