Physical description ( anglais )

fourni par INOTAXA archive
Not very densely clothed with greyish scales tinged slightly with green; these are more condensed in certain places, so as to give a slight appearance of longitudinal bands. The antennæ are black, elongate, the second joint of the funiculus nearly twice as long as the first. Head and rostrum setose and sparingly squamose, deeply canaliculate along the middle, with a slight carination of the side over the insertion of the antennæ. Thorax with a short, very deep canalicular impression at the base in the middle; the sculpture moderately coarse and not close, obscured by the clothing. Elytra with fine, erect, short hairs, the greenish-grey squamosity not so distinct in some places and thus giving rise to the appearance of two somewhat abbreviate and indefinite black bands.
 
Fourteen examples have been obtained of this species; they do not vary much. There is a well-marked difference between the sexes, the male having the rostrum longer, more distinctly carinate on each side, and the antennæ a little longer and thicker than in the female.
