$. — Ferruginous; antennae fuscous apically; clypeus rounded 

 anteriorly ; eyes almost reaching base of mandibles diverging above, 

 separated on the vertex by a distance about equal to the first three 

 antennal joints ; space between hind ocelli distinctly less than that 

 between them and eyes; antennae long and slender, first joint of 

 flagellum but little longer than second; occiput slightly prominent 

 behind ocelli; pronotum strongly arcuate; middle segment subcon- 

 vex, sloping from base to apex ; legs tolerably spinose, hind tibiae 

 strongly serrated, its longer spur nearly or about equal to half the 

 length of first hind tarsal joint; abdomen subpetiolate, the first seg-

 dense silvery pubescence, the remainder of the body with cinereous 

 pile ; clypeus with fore margin subtruncate, about three times or 

 more broader than long; front scarcely impressed; eyes almost 

 reaching base of mandibles, the space between them at top rather 

 less than that at bottom, a little greater than the combined length 

 of antennal joints 2 and 3 ; space between hind ocelli slightly less 

 than that between them and eyes ; pronotum angulate behind ; 

 middle segment short, rounded, not impressed, but with a triangular 

 fovea at base above; legs feebly spinose, hind tibiae delicately ser-

 marginal narrowed about one-quarter above, receiving the second 

 recurrent vein before the middle. Length 6 mm.
