 areas between punctures minutely reticulated, pubescence long, fine; 

 anterolateral angles of pronotum acutely projecting, toothlike, an- 

 terior dorsal carina interrupted on mesal one-third; parapsidal fur- 

 rows partly obliterated; prepectus entirely concealed by projecting 

 lateral margin of mesoscutum ; apex of mesoscutellum with a rather 

 wide lamina; metepisternum strongly and densely punctured except 

 at posteroventral angle, pubescence sparse and fine; metacoxae gla- 

 brous, provided, except on outer dorsal surface, with long setae ; outer

 setae, basal tooth large, acute, followed by 13 or 14 small acute teeth ; 

 inner tooth wanting ; apex of metatibia long, slender, acute. 



Propodeum provided with long setae at posterolateral angles, sur- 

 face provided with large, strong carinae, areas between carinae al- 

 most glabrous, spiracular openings small, vertical, no lateral projec- 

 tions present on propodeum; petiole glabrous, provided with several 

 long, lateral setae, basal lamina narrow, interrupted at dorsolateral 

 angles; gaster compressed, usually slightly longer than metafemur, 

 abdominal tergites 3 to 7 each with long lateral setae ; eighth tergite 

 densely covered by minute pits, setae long, sparse, spiracular openings 

 oval ; cerci oval, located midway between anterior and posterior mar-

 short ventral setae. 



Male : Unknown. 



Type locality. — Mexico. 



Types. — Holotype, female, 1811.1; paratypes, 1811.2, 1811.5, 2 fe- 

 males : Academy of Natural Sciences of Philadelphia. The two sup- 

 posed paratypes of this species labeled 1811.3 and 1811.4, in the 

 collection of the Academy of Natural Sciences of Philadelphia, 

 unquestionably represent another species. The original description 

 of this species states that it was described from both males and 

 females, but all the type specimens are females. 



Host. — Unknown. 



Distribution. — Texas: Brownsville, November 25, 1910, 1 female. 



Mexico : 3 females (holotype and paratypes) .
