O. hildagi Sauss.; Rev. et Mag. de Zool. IX, (1857), 275. 

 O. hildagi Sauss.; Syn. Am. Wasps Sol., 252-254; 1875. 



o . Total length, 13-14 mm.; wing, 10-11 mm. 



^ . Total length, 11 mm.; wing, 8 mm. 

 A medium-sized, rufous, black and yellow wasp. 



o . The following description is taken directly from De Saussure, 

 with two slight omissions: Clypeus punctured, widely truncate, its 

 inferior part rather flattened and laterally bicarinate. Thorax in the 

 form of an elongate square, not contracted posteriorly, densely and 

 coarsely punctured. Postscutel sharply truncate, strongly crenulate. 

 Metathorax very rough in its superior lateral face, its posterior con- 

 cavity strigose, shining; margined with sharp edges, which form on each 

 side a very strong dentiform angle, and which terminates superiorly in 

 two eminences ' separated from the postscutel by deep fissures. Abdo- 

 men silky, quite conical, not ovate; its first segment large, as wide as the 

 second, sharply truncate anteriorly, the margin of the second and follow- 

 ing segments quite coarsely cribrose; the border of the second and third 

 segments reflexed. Insect rufous and black and yellow, head black; 

 mandibles, clypeus, margins of the orbits entirely or interrupted at the 

 vertex, a spot on the foiehead, and at the base of the antennae rufous; 

 mesonotum black; prothorax, scutellum, metathorax and tegute rufous; 

 anterior margin of prothorax and a spot below the tegulse refous or 

 yellow. Abdomen rufous, all segments margined with yellow; the mar- 

 gin of the first segment widened at the base; triangular black spots at the 

 base of the first and second segments; on second this spot is very large, 

 sometimes covering half of the dorsal surface. 



7 . Clypeus octagonal. Mandibles, orbits, a triangular spot on the 

 forehead, a line on the scape of the antenna, yellow. Margin of pro- 

 thorax, scute!, a spot under the base of wing, and tibia, often yellow. 



Habitat: De Saussure records species from New York, Louisiana, 

 and Mexico. In the Snow collections are specimens from Kansas, New 

 Mexico, and Arizona. 



0. papagorum Vier. 

 O. papagonm Vier; Trans. Am. Ent. 88, 394-395; 1907. 



o . Total length, 9 mm.; wing, 7.5 mm. 



f . Total length, 8 mm. ; wing, 7 mm. 



A small black wasp, ornamented with yellow. 



o . Clypeus pyriform, terminated apically by a very small concave 

 edge, rather coarsely punctured. Thorax elongate; metathorax narrowed; 

 its concavity strigate-punctate ; its superior lateral margins effaced by 

 punctations. Abdomen ovate; the first segment subcampanulate, much 

 narrower than second segment; cell segment punctate, most coarsely on 

 borders. Black. The following yellow : edges of the clypeus except a 

 bleak laterally on each side, a frontal spot, a mark immediately above the 

 insertion of the antennse, a mark in the emargination of the eyes, a 

 postocular line, the anterior border of the pronotum, a spot below the 

 tegulse, a dot near the posterior margin of the scutum, postscutellum.
