 fa(!e Ktronj^ly decilivous, niakinj^ the head ai)pear tiianj^iihir from side; 

 scrol)es seniicirenlar; mandibles nliort, .'{dentate. Antennae inserted 

 at border of mouth; scape with a strong leaf-like expansion; pedicel 

 rather slender, about twice as lonf^ as broad; the O-jointed funiclein 

 crejising rapidly in width from joint 1 to joint 0, joints 1 to '} sul)efjual 

 in length, J as broad as long, '.i twice as broad as long, .'» to (> iin;reas- 

 ing somewhat in length, G about twice as broad as long; club flattened, 

 obliquely truncate, as h)ng as entire funicle, and at its middle nearly 

 twice as wide as funicle Joint 0. Mesonotum rather strongly convex; 

 scapulae meeting at tips; mesoscutellum bare; metanotum bare.
