MONOGRAPH OF THE NORTH AMERICAN PROCTOTRYPID.E. 381 



Antennpe inserted on n frontal prominence, 14 jointed, filiform in both 

 sexes, or in 9 sometimes sliglitly incrassatedtowardtips, the joints, for 

 the most part, moniliform or snbmoniliform, the last conic or ovate; in 

 the S the joints are cylindrical, the first flagellar joint the longest and 

 nsnally excised at base. 



Thorax as in Cinetus. 



Wings pubescent, with a basal cell and a closed marginal cell, the 

 stigmal vein usually oblique (rarely straight), the marginal vein very 

 sliort, seldom much longer than the stigmal. 



Abdomen obovate or conic, the petiole two or three times as long as 

 thick, the second segment with a longitudinal sulcus at base. 



Legs as in Aclista, the basal joint of hind tarsi less than three times 

 as long as the second ; tibial spurs short, but distinct. 



No type seems to have been described or indicated by Forster, but 

 the genus is a valid one, readily distinguished by the 14-jointed antenna? 

 in female, and the closed marginal cell. 



Only two other genera have 14 jointed antenna^ in the 9 , viz, 

 Anommatimn and Paniolyta; the former is wingless and without ocelli, 

 the latter winged but without a marginal cell.
