 the palpi and the legs, except the swollen anterior femora, which are rufo-piceous, are 

 yellow. The head and the anterior lobe of the thora.x are coriaceous, the posterior 

 lobe of the thorax being strongly transversely striated. Abdomen oval, not longer 

 than the posterior lobe of the thorax, but broader, smooth and polished, the petiole 

 black, some of the segments tinged with blackish, while the hypopygium is yellow. 

 The antennae are slightly thickened toward apex and extend a little beyond the base 

 of the posterior thoracic lobe, with the third joint the longest, about as long as joints 

 4 — 5 united.

%. Length 3 mm. Reddish ; the vertex of the head is du.sky, the lobes of the 

 thorax beneath and the petiole of the abdomen are blackish, while the antennae and 

 the legs are wholly yellow. The sculpture of the species is almost exactly as in

 of it.
