Base of the thorax stoutly obHquely distinctly projecting laterally, the pro- 

 jection longer than it is thick at the base, narrowed and rounded at the apex. 

 Clypeus clearly broader than long, rounded broadly above and below, widest 

 in the middle, the top not so broad as the bottom. Head and thorax closely 

 punctured, except the metapleurae which are aciculated, sparsely punctured, and 

 obscurely striated. Postscutellum strongly punctured at the base, the rest 

 smooth and shining ; it has an oblique slope and its apex is broadly rounded. 

 First abdominal segment cup-shaped, strongly punctured, especially before the 

 apex, which is smooth and raised. The second segment is less strongly, but 

 more closely punctured, except at the apex, which is slightly raised. The 

 other segments are more closely punctured. Antennal hook black, not quite 

 reaching to the apex of the last joint. Trophi long, reaching beyond the mid- 

 dle coxae. 



Odynerus tosquineti sp. nov. 



Black, the abdomen rufous, the clypeus, mandibles except at apex, underside 

 of antennal scape, a broad line narrowed in the middle on the apex of prono- 

 tum, tegulae except for a fuscous spot in the middle, scutellum broadly, a large 

 spot below the tegulae longer than wide, transverse above and rounded and 

 narrowed below, a broad line on the top of the first abdominal segment, a 

 broader one on the second, all around, considerably dilated aliove, the apex 

 of the femora narrowly and the greater part of the tibiae, whitish yellow. 

 Flagellum of antennae brownish red, darker at the apex above. Wings hyaline, 

 the stigma fuscous, the nervures blackish. Male, length 5 mm. Claremont, 

 California (Baker). 



Front and eye incision densely covered with silvery pubescence, the rest 

 of the head and body with shorter and sparser silvery pubescence. Head and 

 thorax strongly punctured, the puncturation on the pronotum and clypeus 

 sparser and weaker on the metathorax than on the mesothorax, the lower part 

 of the metapleurae almost smooth. The apical slope of the median seginent 

 is red, as is also the apex of the metapleurae. Clypeus longer than wide, 

 rounded above, the apex with a V-shaped incision. Base of thorax not quite 

 transverse, being slightly dilated in the middle, the sides are almost rounded. 

 Postscutellum large, transverse at the apex. The sides of metanotum rounded 

 and with two pale teeth. The apices of the two basal segments of the alxlo- 

 men are slightly raised, closely and strongly punctured, the first is sup-shaped, 

 the second about one-fourth longer than it is wide, its a])ex more strongly 

 punctured than the rest. The antennae are thicker than usual, the hook 

 black and reaching to the apex of the last joint. The second abdominal seg- 

 ment is not much narrowed at the base. The four anterior tibiae are broadly 

 lined with black behind ; so also are the posterior, which have besides a line 

 on the inner.side. The apical segments of the alidomcn are darlscr colored 

 than the basal two. 



Odynerus aciiticarinatiis .sp. nov. 



Black, two curved lines or spots nn the top of the cly])eus ;il the sides, a 

 narrow indistinct line across the l)ase of \hr ]irnnntuni, a narrow hut (li'^tincter
