Anterior border of clypeus very gently convex, almost straight; lateral teeth triangular, not projecting. Frontal area impressed. Frontal lobes semicircular. Frontal carinae almost straight, diverging caudad, attaining tip of occipital corner. The latter scarcely, salient. Front with a weak and low tumulus just behind frontal area, followed by a shallow transverse depression between greatest constriction of frontal carinae. Carinae of vertex strong, subsemicircular, diverging both cephalad and caudad, the posterior end does not attain the occipital corner. Occiput perpendicular to vertex, distinctly excavate. Preocular carina curving mesad above eye; postocular carina extending from occipital corner to the inferior border of eye, containing the supraocular tooth, which in full-face view appears just as a blunt angle of postero-lateral border of head. Eyes with 7 facets across greatest diameter. Inferior border of cheeks sharply marginate. Antennal scape gradually but strongly incrassate toward apex; surpassing in repose the occipital corner by a distance which distinctly exceeds its maximum width. Funicular segments II-IX not longer than broad, segment I as long as II and III combined.</paragraph>

<paragraph id="1462E6FDEEC834B710ABC429DA9CA458" pageNumber="182">Thorax as shown in Fig. 20. Midpronotal tubercles absent. Lateral pronotal tooth tubercular and obtuse, sending foreward a weak carinule which separates the pronotal dorsum from its sides; anteroinferior corner rectangular. Humeral angle not expressed. Mesonotum with a shallow pentagonal impression margined by blunt carinae formed by the very low and weltlike anterior and posterior pair of tubercles; the latter form at the antero-lateral corner a bluntly projecting tumulus. Mesoepinotal constriction rather strong. Basal face of epinotum laterally immarginate with two indistinct tubercles antero-laterally, blending posteriorly into the declivous face, which is laterally immarginate. Oblique welt on sides of epinotum indistinct. Hind femora (Fig. 50) ventrally angulate at basal third, postero-ventral border narrowly crested.</paragraph>

Petiolar node nearly twice as broad as long, the anterior corners rounded, posteriorly strongly constricted in front of postpetiolar insertion; no dorsal ridges nor posterior salient laminule present. Postpetiole without a distinct anterior face, its dorsal face with a sagittal impression and postero-lateral impressions flanking a pair of blunt and low tubercles, which do not project beyond the entire posterior border.
