3.? Adrisa flavo-marginata Vollenhoven , Versl. Akad. Arnst., Natuurk. II: 177, 14, 1868.

One specimen, Machanao, June 4, on the ground, Usinger ; one specimen, Mt. Alifan, June 27, Usinger ; one specimen, Barrigada , July 22, under chips, Swezey .

These specimens were collected in a dead and dried condition with all appendages except a middle and a hind femur and rostrum of one specimen broken off. Hence the identification of these as a New Caledonian species is questionable. Even the generic assignment is doubtful because the number of antenna! segments is not known.

The specimens agree fairly well with Signoret's description and figure (Soc. ent. France, Ann. VI, 1: 212, pl. 8, fig. 33, 1881) but the pronotum is almost entirely black and the ocelli are practically invisible. Only in one specimen is there even a trace of ocelli. This condition is at once suggestive of the New Zealand Choerocydnus albosignatus Buchanan White, but the Guam specimens differ from this in color, puncturation, and form of ostiolar canal.
