A specimen of this genus, lacking head and thorax, was found by R. L. Usinger June 27, 1936 on Mt. Alifan; its reddish brown elytra measure 12 mm . in length. It is very different from the Polynesian S. cinnamomeus (Boisduval) . The Mt. Alifan insect appears similar to S. hesperius Van Zwaluwenburg from Palau and the Carolines, and to S. palauensis Van Zwaluwenburg from Palau ; like them, it bears a resemblance to some of the Philippine species of the genus. Its occurrence in the mountain forest suggests that it is native to Guam .
