 lowly and closely punctate, appearing somewhat granulate; abdomen strong- 

 ly punctured throughout, without any evident spines on the sides. Color 

 black; mandibles except the reddish tips, minute lateral spots on first tergite, 

 anterior and intermediate tibiae and tarsi, stripe outwardly on the posterior

Type, a male collected at Omaha, Nebraska, July 16, 1914, on 

 Chamaecruta fasciculata, (L. T. Williams). 



Related to emarginata, but differs from that species in the 

 much smaller size, the striato-punctate episterna, the peculiarly 

 sculptured sides of the propodeum and in the shape of the meta- 

 notal spine.

c^. Length 7.5 to 9 mm. Clypeus shining, three-toothed but not strongly 

 so; front strongly, longitudinally striato-punctate; vertex and occiput coarsely, 

 transversely striato-punctate; space between the two posterior ocelli about 

 two and one-half times the distance between one of them and the nearest eye- 

 margin; pronotum strongly margined anteriorly; mesoscutum strongly and 

 coarsely punctate; episterna coarsely reticulate; mesoscutcllum strongly 

 punctured; mesoscutellum and metanotum with a distinct, longitudinal, 

 median carina; squamae with a very strong lateral point which does not reach 

 to the tip; metanotal spine about as long as the mesoscutellum, broadened at 

 the tip and roundly emarginate; upper surface of propodeum obliquely rugose, 

 reticulate beneath the spine; posterior face of propodeum transversely rugose 

 except the median area, which is triangular, smooth and shining within; 

 sides of propodeum finely, transversely rugose; abdomen distinctly 

 punctate, the punctures on the first segment stronger than those on the 

 following segments; hind tibiae with three rows of stout, sharp spines on the 

 outer face, the space between the rows strongly rugose. Color black; spot on 

 the squamae, narrow apical bands on tergites one to four narrowly inter- 

 rupted medially, apical bands on tergites five and six, line on anterior tibiae 

 in front, spot at base of intermediate and posterior tibiae, all very light yellow- 

 ish; anterior tibiae and tarsi, and flagellum beneath at the apex reddish brown;
