terior and intermediate tibi^ armed on both margins, both above and

 breadth. Ovipositor nearly as long as the posterior femora and 

 curved moderately and uniform!}^ upwards. 



Color wood-brown, the sides of the pronotum a little darker, the 

 upper posterior portion shiny piceous; sides of the abdomen shiny 

 black, strongly contrasted with the brown dorsum; posterior femora 

 with two longitudinal black streaks on the outer face; ovipositor, legs, 

 and face tinged with reddish brown. 



Measurements. — Length, pronotum, 6 mm.; posterior femora, 18; 

 ovipositor, 17; width, pronotum across the metazona, 8.5; posterior

Specimens examined. — One female, labeled "Colonia Garcia, Chi- 

 huahua, Mexico" (Townsend). The specimen was presented to the 

 U. S. National Museum b}" Bruner. 



The slight development of the thoracic carina? and the absence of 

 visible wings will readily separate this Mexican species from the United 

 States forms.
