 running into striations in the oblique hollow on the mesopleurae and on the metanotum, 

 which latter has an arcuated transverse keel at the base, behind which the punctuation 

 is finer ; the centre of the metanotum hollowed ; scutellum closely punctured. Petiole 

 shining, impunctate ; postpetiole aciculate and black above ; the other segments also 

 black above, the second and third finely and closely punctured ; the ventral surface is 

 honey-yellow, the sides rufous, wanting the fuscous tint noticeable on the thorax. The 

 legs are pilose, the tibiae (especially the hind pair) being covered with a very stiff pile ; 

 the extreme tips of the front tarsi, and the apical halves of the middle tarsi, black ; 

 the four hind coxae more or less rufous. Wings hyaline, with a faint fuscous tint ; 

 areolet triangular, pedunculated. Antennae three fourths of the length of the body ; 

 scape rufous. Palpi and mandibles yellow.
