T^eugcli 13, terebra 4 mm. 



Antennae, with joints &-)^, white beneath ; head opaque, closely 

 punctured, the clypeus more shining and more widely punctured 

 than the face, which is roundly dilated above in the centre; front 

 deeply and widely depressed ; the upper two-thirds with a stout 

 longitudinal keel down the centre ; the rest closely transversely 

 striated : there is a brownish line on the middle of the inner 

 orbits. Thorax closely rugose : the apex and the lower part of the 

 propleurse strongly striated ; the metapleuras more coarsely than 

 the meso-, the punctuation running into reticulations : the apex of 

 the meta- stoutly, irregularly, obliquely striated-reticulated. 

 Scutellum more shining and less closely punctured than the 

 mesonotum ; its sides stoutly keeled to near the apex, which is 

 irregularly striated. The part between the 2 metanotal keels is 

 irregularly reticulated ; the apex is more closely punctured-reticu- 

 lated ; the tooth on the sides of the basal carina is short, on the 

 second it is stouter and more distinct ; on the base of the segment, 

 in the middle, is a small triangular area. Abdomen smooth and 

 shining. There is a longish stump of a nervure on the disco- 

 cubital ; the recurrent nervure is received almost in the middle of 

 the areolet ; transverse basal nervui*e interstitial. The tarsi are 

 darker coloured than the tibi^ and are closely spined. There is a 

 distinct keel down the base of the propleurse, extending from the 

 top to the bottom ; the clypeus is not separated from the face by a 

 furrow : the labrum and mandibles above, in the middle, rufous : 

 malar space as long as the antennal scape; the basal metanotal keel 

 is shai'pl}- projected backward ; the projection is sharply pointed 

 and is united to the basal area ; metanotal spii-acles small, about 

 3 times longer than wide ; the metapleurae project into a small 

 tooth at the apex below.
