MONOGliAPH OF THE NORTH AMKKICAN PROCTOTRYPID.*:. 413 



Alxlonioii oblonp oval, in 9 sliowinj; 7 aognu'iits; the petiole short, 

 woolly; tlie seeoiul sej;ineiit occupy illy' nea/ly the whoh' aurface; iu <J 

 8-s«'«,'inente<l, the petiole loiifjer. 



Lej;s moderate, the feni(»ra ami tibije clavate, the tibial sjmrs weak, 

 the basal joint of hind tarai fully twice as loiij; as the setroud, in the i 

 soinewliat shorter. 



This {jenus wasorijiiiially confused with Diapria, but is at once distin- 

 jfiiished fnun it and closely allied j;enera by the frontal impression, 

 the shape of the scutellum, and the distinct basal nervure. In the 

 shape of the head the fennile, in many species, recalls somewhat Gale- 

 sus, but the winj;s and antennae are quite different. 



Our species may be distinj;uished by the following table:
