The following is a modified, reformatted OCR version of Ashmeads’ original description (1893). The type specimen is dark reddish brown, not black, as the description states. Some terminal antennal segments are missing on both antennae. The horn does not extend to the vertex, and the latter is slightly impressed in the center. Striation at the base of the horn is deep and parallel. There are weak foveal striae on T-II, extending to the basal third of the segment, but this is best appreciated if the specimmen is rotated in good light.

microscopically punctate, the vertex slightly impressed in the middle, the face with a median furrow, the lateral ocelli a little away from the margin of the eye.

Antennae 10-jointed, brown-black, the apex of pedicel yellowish; first funiclar joint slender, more than twice longer than thick; second two-thirds the length of the first; third and fourth minute; club 4-jointed, the joints, except the last, a little wider than long.

Thorax smooth, shining, with distinct furrows, the scapulae with a faint trace of an impressed line; mesopleura polished foveated; metapleura finely delicately punctate with a deep sulcus. Wings hyaline.
