cint. Abdomen: first two segments shining black ; third and fourth bright yel- 

 lowish red, very narrowly black along the lateral margins; fifth and sixth of the 

 same color, but more broadly black on the sides, brilliant silvery when viewed 

 from in front, less intense and finally not apparent when seen from behind. The 

 first three segments are parallel on the sides, of nearly the same width as the 

 thorax ; from the beginning of the fourth to the tip of the fifth the sides are 

 nearly straight, but divergent, so that at the tip the abdomen is fully a fourth 

 wider; sixth segment convex behind. The abdomen is bare, except the sparse, 

 very short, recumbent hairs, very much flattened, especially at the tip, the sixth 

 segment projects eave-like much beyond the hypopygium, which is small and 

 retracted. Legs rather slender, the tibiae and tarsi spinose, but not strongly so; 

 liind femora slender, elongate, a little thickened just before the tip; hind tibiae 

 elongate, slender on the basal two-thirds, much thickened, club-like at the end ; 

 hind tarsi much thickened, especially the first joint, which in length is little less 

 than the three following together. In color the legs are deep pitchy black, on the 

 under side of the femora, and sometimes the tibiae also deep red ; bristles and pile 

 mostly white. Wings elongate, all the posterior cells open ; blackish, the third, 

 fourth and fifth posterior cells chiefly, the anal cell wholly, the basal cells in part, 

 the costal cell except the tip, and slender spots along the veins opposite the distal 

 part of first vein, hyaline. 



Two specimens. California (0. T. Baron).

9. — Yellowish red; the second segment of ab<lomen with a small semiovai 

 black spot at base. Wings hyaline on basal third, on distal part variegated with 

 brown. Length 10-11 mm. 



Face dark red, slightly shining, on the sides and upper angles and on the lower 

 part with yellow pubescence: bristles like the face, yellowish on outer part; pile 

 short, very sparse. Antennae yellowish red, the basal joints a little darker; first 

 joint scarcely at all longer tiian the second, style comparatively longer than in the 

 preceding, nearly half as long as the third joint. Front opaque. Dorsum of 

 thorax opaque brownish red, on each side of the middle in front a small spot, and 

 back of the suture above the wings a larger spot of a darker, more reddish brown 

 color; in front of the scutellum in the middle, a small, oval, shining space, on 

 either side of which the color is golden yellow: along the suture on each side a 

 slender, yellowish gray stripe. Pleurae thickly reddish yellow and grayish 

 pubescent. Abdomen shining red : the second segment at the base with a narrow, 

 transverse, semioval, shining black spot; on the anterior and posterior angles of 

 the second segment with a small, on the posterior angles of the third and fourth 

 with smaller silvery spots ; the fifth segment on the side with a large triangle, 

 narrowly separated from the one of the onposite side, and the sixth and seventh 

 segments wholly opaque yellowish. In sliape the abdomen has parallel sides to 

 the tip of the second segment, thence widens to the tip of the fourth, thence on 

 the sides more rapi<lly convergent. Legs wholly red, the coxae yellowish opaque, 

 the bristles light colored. Wings a little broader than in abdominalis, the anterior 

 cross-vein near middle of discal cell: on basal third (except extreme base) hyaline, 

 beyond variegated with brown, darker across the middle, the cross-veins and along 

 the veins at tip.
