Most closely related to spilnptenis and nelmlosus, more re- 

 motely to splendiduhis. These four species may be distinguished 

 as follows: 



1. Antennae slender, in the female the third segment longer than the dis- 



tance between the hind ocelli. Color rufous, marked with j-ellow. 



splendidula new species 

 Antennae short and thickened, the third segment not as hnig as the dis- 

 tance between the hind ocelli. Color black, with yellow and rufous 

 markings (-) 



2. Angles of propodeum coarsely rugose; abdomen scarcely punctate at base, 



shallowly and not coarsely punctate on the fifth dorsal segment; legs 

 black, the femora and tibiae variegated with yellow and red; scaitellum 

 with two yellow spots; propodeum and abdomen witliout rufous. 



adornata new species 



Angles of propodeum not at all, or but slightly rugose; legs not colored 



as above; scutellum with an uninterrupted bar of yellow; abdomen 



l)unctate basally; the fifth dorsal more deeply and coarsely punctate. . (3) 



3. Legs red, the middle and hind tibiae yellowish at base; propodeum and 



base of first segment of abdomen red spilopterus Handlirsch 



Legs castaneous, the middle and hind tibiae yellowish at base; propodeum 

 and abdomen without red nebulosus Packard 



Probably s])ilo])teri(.'i should rank as a western race of nebu- 



Gorytes (Hoplisoides) imperialensis new species 



,^. Black, yellow and red; the following parts yellow (baryta yellow): 

 scape and pedicel beneath, face below antennae, clypeus, labrum, mandibles 

 except tips, stripe extending up along eye margins to two-thirds of the dis- 

 tance from the in.sertion of the antennae to the front ocellus, fine line on side 

 of collar, broad posterior border of pronotum, continuous with tubercles, 

 vertical stripe on mesopleura above, scutellum, spot on postscutellum, large 

 lateral spots on propodeum, apical half of first dorsal segment, incised medially, 

 sinuate apical bands on second to fifth dorsal seginents, widened laterally, 

 spot on ultimate segment, subapical band narrowed medially on the second 

 and lateral spots on the third and fourth ventral segments, spot on all coxae 

 in front, apical part of all tibiae beneath or behind, front and middle tibiae 

 except beneath, and hind tibiae beneath only, front and middle tarsi entirely, 

 and hind metatarsi except line beneath; the following parts are rufous, flagel- 

 lum at base beneath slightly reddish, lateral surface of pronotum, sides of 

 propodeum in front of and below yellow spots, shading into black anteriorly, 

 sternum from in front of middle coxae to petiole, first and second ventral 

 and extreme sides of first and second dorsal segments except where yellow, 

 and legs entirely except where described as yellow. Body covered with 

 short white pubescence, giving it a conspicuous grayish bloom. Wings 

 stained slightly yellowish brown, and with a distinct golden reflection; a
