1917] A Synopsis of EumenidcE 353 



Eumenes stenogaster new species. 



Female. — Length, 13 mm.; wing, 10 mm. Clypeus longer than 

 wide, lateral angles nearer base than in fraternus, apical emargination 

 moderately deep, angular, basal emargination narrow, rounded, surface 

 coarsely punctate; thorax truncate in front, convex laterally, median 

 furrow of propodeum deep; petiole campanulate, nearly half as wide at 

 apex as long, punetations deep and of medium density; second segment 

 of the gaster depressed, as wide as long, dorsal angle rounded, lateral 

 angles attained far before the middle, beyond these angles the lateral 

 lines are nearly parallel, punetations as on petiole. Black; clypeus, 

 except a pedieulate spot suspended from the basal margin, a line on 

 the anterior aspect of the scape, the ridge between the antennae, anterior 

 margin of the prothorax, a dot on either side of the anterior margin of 

 the mesonotum in front of the tegulse, a spot below the tegulffi, an 

 obscure dot on either side of the scutellum, metanotum, large oblique 

 spots on either side of the propodeum, a large spot on either side of 

 the petiole, a broad oblique band on either side of the second segment 

 of the gaster nearly meeting on the dorsum, apical margins of all the 

 segments of the gaster except the last, particularly wide on the second 

 segment broadening into a helmet shaped spot ventrally, ends of 

 anterior and median femora, the same pairs of tibiae, yellow; all tarsi, 

 ends of posterior femora and posterior tibiae, testaceous; wings sub- 

 hyaline, brownish; body covered with dense grayish pile, finer on the 

 second segment of the gaster. 



Male. — Length, 13 mm.; wing, 10 mm. Clypeus broad for a male, 

 distinctly toothed, gaster less densely and coarsely punctate than 

 that of the female. Clypeus all yellow, tegulae margined with yellow; 

 hook of antennae, brown. Otherwise as the feamle. 



Described from one female collected by C. H. T. Townsend, 

 Rio Ruidoso, White Mts., N. M., and one male from Beaver 

 Canyon, Utah. 

 ■ Type.—C^i. No. 21379, U. S. National Museum. 



Eumenes sternalis new species. 



Female. — Length, 12 mm. ; wing, 10 mm. Clypeus longer than wide, 

 lateral angle little more than midway from base to apex, slightly convex, 

 flattened apically, apical emargination rounded, basal emargination 

 narrow and shallow, surface finely punctate; thorax convex laterally, 

 median furrow of propodeum shallow; petiole abruptly campanulate, 

 medium width, as wide or wider before apical contraction than after it; 

 second segment of the gaster depressed, a little longer than wide, wide 

 transverse depression before the apex extending to the sides, lateral 

 angles distinct, nearer base than apex, lateral lines beyond angles 

 converging apically; punetations on gaster shallow and of medium 

 density. Black; clypeus except a central spot, a line on the anterior 

 aspect of the scape, the ridge between the antennae, a very fine post- 

 ocular line, anterior margin of the prothorax, a spot below the tegulae,
