Descriptions of new genera and species of Phytophagous Coleoptera

The Sumatran specimens before me, belong with one exception to the var. a. of Lacordaire, in which the underside and the antennae are entirely fulvous; in these specimens, not only the anterior legs, as Lacordaire’s description says, but all are of the same colour. The species seems to vary greatly in this respect, the underside, legs and antennae being either fulvous or black. I may further add to the author’s description that there is a more or less distinct trace of another transverse thoracic depression anteriorly in all the specimens which have come under my observation and which is frequently the case in other species from the eastern parts of the world.
