front; ocelli minute, the posterior pair .08 mm. in diameter, .78 mm. or nine 

 times as far from the eyes; face and clypeus with a raised, polished, and impunc- 

 tate triangle with its apex between the antennae; the depressed sides of the 

 face polished and impunctate; margins of the clypeus with a slight emargination ; 

 mandibles exceedingly robust and awry, a large tooth on the lower margin 

 near the base. Scape hirsute, with a longitudinal keel; third segment longer 

 than the pedicel, two-thirds as long as the fourth. 



Pronotum, mesonotum, and scutellum coarsely, closely punctate, side pieces 

 of pronotum with a .sharp anterior carina; anterior portion of mesosternum on 

 each side of the median line with a large rounded swelling, not carinate; just 

 in front of the middle coxae is a high triserrate peg-like process on each side of 

 the mesosternum; propodeum coarsely reticulate, with a poorly defined 

 double basal area. 



Petiole rather long and very trongly gibbous, constricted from the second, 

 the posterior part being almost at right angles to the dorsal surface, weakly 

 and sparsely punctured; second dorsal segment with sparse small punctures, 

 its apex and that of the remaining segments closely punctulate and bearing 

 numerous long white hairs; pygidium closely punctulate; the venter unarmed, 

 its last segment broad, slightly concave and closely evenly punctate. 



Type material. — Holotype: Falls Church, Vh-ginia, July 21, 

 (N. Banks), [Cornell Univ. No. 107.1]; six paratopotypes: June 

 14, July 4, 6, 28, August 30, one paratype from Great Falls, 

 Virginia, July 7, (N. Banks), [paratypes in the collections of N. 

 Banks, Amer. Ent. Soc. and Cornell Univ.]. One paratype taken 

 on Ceanothus. 



The very long head of this species and the peg-like processes 

 on the mesosternum abundantly distinguish it from all known 

 species. The only other described totally black species is quin- 

 Hlis Viereck.
