The labrmn is obconical, rounded at the tip, hiding the base of the mandibles, which are slender and sickleshaped.
The maxillary palpi are scarcely so large as the labial, the first and fourth joints being the shortest •
the fourth IS pointed at the tip. The labium is large, porrected, and obcordate, the apical margin nearly
