This almost cosmopolitan sweet-potato pest (commonly called the West Indian sweet-potato weevil) is easily recognized by its subparallel-sided, densely squamose elytra which have a common, transverse, pale fascia at the top of the declivity. The pronotum bristles with erect, spatulate setae, borne from rather large, close punctures; the interstices between the punctures are coarsely reticulate.

The following specimens from Guam are before me: three, Piti, from sweet-potato vine, Nov. 17, 1936, Swezey ; two were taken by Fullaway but have no specific locality other than " Island Guam."
