 mandibles black. Mesonotum shining, obsoletely punctured, the furrows deep ; the 

 pleurae longitudinally and finely punctured. Scutellum shining, impunctate, covered 

 with longish fuscous hair, not much raised above the mesoscutum, the fovea at the base 

 not very deep. Metanotum above the upper transverse carina shining, punctured ; below 

 it strongly striated transversely ; a broad deep furrow on either side ; the second 

 transverse carina obsolete, the first nearly straight ; metapleurae longitudinally striated. 

 Petiole long, curved, shining, impunctate ; the rest of the abdomen microscopically 

 aciculate, covered with a* microscopic down ; the greater part of the third and the fol- 

 lowing segments entirely reddish. Coxae and trochanters shining, impunctate, covered
