Antennse about as long as the abdomen, the flagellum 
about one-fourth longer than the scape; 11-jointed, the 
flagellum becoming thicker towards the apex, the third joint 
nearly three times the length of the second. Head flnely 
punctured — the punctures very shallow — the face in centre 
finely transversely striated ; two keels run down from the 
centre to the antennse, diverging towards the apex; the face 
is nearly perpendicular and is continuous with the vertex ; 
ocelli in a curve, and placed on the top of the head, the top of 
the eyes being on a level with them. Thorax rather strongly 
punctured; the prothorax four times broader than long; 
parapsidal sutures deep ; a transverse furrow in front of the 
scutellum, which is large, very strongly punctured and 
unarmed ; mesopleurse excavated obliquely, the excavation 
reaching to the sternum, shining, obliquely irregularly 
striated; in front of it the pleura3 are crenulated; meta- 
thorax reticulated, flattish ; two keels run down the centre 
united by some transverse ones; and on either side of 
them are some irregular arege. There are no teeth on the 
sides, but there are two irregular ones on each side under 
the petiole, which issues from the upper side of the meta- 
thorax. Petiole about three-fourths of the length of the 
abdomen, stoutly keeled, the space between the keels deep, 
shining. The second segment a little longer than the petiole, 
being as long as the petiole and the other segments united ; 
the back is irregularly black, and the abdomen altogether is 
rather compressed. The thorax is covered with short hairs; 
the metapleurae with rather long white ones ; the abdomen 
is glabrous. Legs shortly pilose ; hind coxae as long as the 
femora, which bear beneath ten short stout teeth; the hind 
tibiae bear a stout black keel on the underside, and end in 
a stout curved tooth ; the four anterior tibiae have no spurs. 
Wings hyaline, suffused with fuscous in the middle ; the ulna 
about one-fourth shorter than the humerus ; cubitus very 
short,
