Unicolorous pitchy brown, with sericeous pubescence forming light and dark patches according to the direction of the hairs. On the thorax this radiates from the mid point of each side of the base forming a basal light patch on each side and a feeble median crest. On the elytra it is directed mainly backwards but with a transverse outward sweep in the middle of the disk and another near the apex. Basal to the first of these, the hairs are mostly dull golden with silvery hairs intermixed, and between the two transverse sweeps entirely dull golden forming vague dark patches on the elytra. Length, 1.5 mm. Piti, April 30, ex Hibiscus tiliaceus (pago) Swezey, two examples; Inarajan, May 6, Usinger, one example; Mt. Chachao, May 16, from Cycas, Swezey , one example; Barrigada, June 12, Usinger, eight examples. Differs from D. sericeovariegata Blair , from Tahiti, in its considerably smaller size and the different pubescent pattern; the antennae also differ, the first joint of the club being thickened on basal two thirds, thence acuminate to apex in the Guam species.
