 lobe of which is broadly truncate, laterally subdentate; mandibles 

 with a strong and sharp inner tooth, of the ordinary type for the 

 genus. Scape not carinate, coarsely punctate; third segment fully 

 as long as the fourth and fifth. 



Thorax narrower than the head, widest at the tegulae, narrowest 

 at the spiracles, behind which it is slightly widened, the anterior 

 margin truncate, tlie posterior face somewhat sloping, flat, rather 

 sharply delimited from the dorsal. 



Petiole without a distinct ventral carina or tooth, pygidium with 

 a distinct area, transversely rugose. 



Holotype. — Huachuca Mountains, Arizona, August 17, 1903 (Os- 

 lar), Cornell University No. 656.1. 



Dr. J. C. Bradley had recognized this species as new and has sent 

 me the type specimen together with the description of the species 

 which he had drawn up and which is given above. 



Specimens examined. — New Mexico: Female, May 16, 1902, Ala- 

 mogordo. 



I also have before me a specimen wliich is apparently the male of 

 aureovestita. The two sexes were not taken in copulation, but I 

 place it here in preference to giving it a specific name.

 erect black pubescence; front and vertex with very close, confluent

 tate ; antennae separated at the base by a distance equal to two-thirds 

 the length of the scape; first segment of flagellum about half the 

 length of the second segment; eyes very slightly ovate; width of 

 head between hind margin of eyes and postero-lateral angles a little 

 less than the longitudinal diameter of the eyes; relative widths of
