longer than the third, thickened and produced at the apex beneath ; the third joint a 

 little longer than the fourth. Face irregularly and rugosely reticulated, broadly but 

 not deeply excavated over the antennae, the depression reaching almost to the ocelli 

 (from which there runs only a very small furrow) ; clypeus projecting, and separated 

 from the face by a wide depression. The oral region bears long white hair; the 

 mandibles are piceous ; the palpi white, hairy. The sternum, pleurae, and metathorax 

 are densely covered with long white hair. The middle part of the petiole is broad, and 

 is bordered by deep, not very wide, and slightly curved furrows. The abdomen is a little 

 longer than the head and thorax together, and becomes gradually narrowed towards the 

 apex. The suturiform articulation is narrow, shallow, and slightly bent backwards in 

 the middle. Cubital nervure broadly curved at the base ; the recurrent nervure 

 received considerably in front of the first transverse cubital one ; second cubital cellule 

 on the lower side longer than the third.

Antennae originating from large tubercles, stout, microscopically pilose, the apical 

 joints fuscous ; basal joint and the scape four times longer than the second joint, its 

 apex dilated; first joint of the flagellum not much longer than the second. Face 

 rugose, the sides irregularly reticulated, the centre transversely striated, the striations 

 running into the punctures. There is a broad, somewhat oval, depression above each 

 antenna, the depressions separated by two curved keels, which approach each other 

 in the middle and diverge outwardly at the base and apex. Apical joints of the palpi 

 fuscous. The lower part of face and metapleurae covered with long glistening white 

 hairs. Centre of the petiole transverse at the apex, the base narrowed ; the surrounding 

 furrow broad, moderately deep. Second segment curved, the sides covered with 

 longish white hair ; second and the following segments without any depressions, the 

 suturiform articulation narrow, curved.
