Antennae stout, as long as the thorax. The basal jonit 

 keeled on lower side ; as long as the second and third joints 

 united ; the second joint one-third the length of the third, 

 which is longer than the fourth. Head as wide as the 

 thorax ; almost opaque, closely punctured ; eyes at the top 

 separated by the length of the fourth antennal joint. A 

 triangular depression above the ocelli, the vertex above 

 this being indistinctly furrowed ; there is a wide depression 

 on either side of the ocelli close to the eye ; and the space 

 between the upper and lower ocelli is widely furrowed in 

 the middle, the furrow being continued beyond the lower ocel- 

 lus. The front above the antennae is widely furrowed along 

 the sides of the eyes, and down the centre. Clypeus distinctly 

 margined at the apex, slightly waved towards the centre. 

 Mandibles black ; somewhat hollowed and finely rugose at 

 the base; the apex piceous. Thorax finely punctured ; the 

 mesonotum shining, the pleurae opaque ; metanotum also 

 opaque, finely rugose. The pronotum is brought to a point in 

 the middle, and its edge bears a covering of white pubescence; 

 the mesonotum is a little depressed in the centre towards 

 the base ; the mesopleural furrow is almost complete ; the 

 ■meta- is shorter than the mesothorax ; its apex is semi- 

 perpendicular and transversely striolated. Abdomen shorter 

 than the thorax ; shining ; the segments edged with a pale 

 short silky pile ; the pygidial area densely covered with a 

 stiff depressed — golden at the apex, fuscous at the base — 

 pile ; and its apex bears stiff golden spines ; its surface also 

 -bearing stiff blackish bristles. At the top the second 

 (Cubital cellule is one fourth of the length of the third ; the 

 recurrent nervures are almost united, and are received a 

 little before the middle of the cellule. The wings are pale 

 across the cubital cellules. The spines, etc., on the legs are 

 black ; the metatarsal brush and the brush on the inner 

 .spur dull fulvous.
