Legs : Femora black, knees testaceous, and tibia brownish-black. 



Male. — Praescutum same as in female. Pronotal spots large, occu- 

 pying one-half anterior dorsal margin of the prothorax. Propodeum 

 with narrow, shallow, margined, median, longitudinal groove ; slightly 

 rugose laterad of groove. Abdomen very slender, sides almost paral- 

 lel. Legs colored as in female. Antennae : Flagellum about as long 

 as head and thorax combined. 



This supplementary description is based on the types in the United

Female. — Praescutum reticulately lineolate and without (rarely 

 with a few) any broad shallow impressions. Pronotal spots large, 

 occupying one-half to two-thirds anterior dorsal margin of the pro- 

 thorax. 



Propodeum with a distinct narrow continuous, median, longitudi- 

 nal, margined groove, which has numerous cross rugae and usually 

 an indication of a central carina ; spiracular carinae not inconspicuous 

 though they are not usually prominent; area laterad of groove rugose, 

 rarely granulose ; fimbria not prominent. 



Abdomen shorter than head and thorax combined ; segment 2 longer 

 than 3 and 4 combined ; 7 usually shorter than 6 ; 3 usually as long as 

 either. 



Legs black except at knees which are testaceous. 



Antennae: First joint of funicle plus ring-joint much longer than 

 pedicel ; neither club nor funicle joints quadrate ; club slightly broader 

 than funicle ; scape black. 



Species ranges from minute to medium in size. 



Male (pi. 47, fig. 7). — Praescutum as in female. Pronotal spots? 

 small but visible from above, occupying less than one-half of the an- 

 terior dorsal margin of the prothorax. 



Propodeal groove usually complete; propodeum rugose laterad of 

 and within the groove; often there is no complete groove and the 

 propodeum is often granulose. 



Legs black except at knees which are testaceous. 



Antennae: Flagellum and pedicel shorter than head, tliorax, and 

 petiole combined; hairs on the first joint of flagellum same length 

 as the last joint of antennae. The last joint of the antennae ends in a 

 long conical spur, about four times as long as broad; scape broadest 

 near the center and distinctly broader than first fla<rellar joint; tw^o to 

 four annulatioiis at the articulation of all flagellar joints except the
