 yellow. Head yellow ; antennas darkened on apical half of flagellum, 

 the plumes golden yellow on their basal half, black on apical half, palpi 

 brown. Mesonotu'm glossy, anterior margin blackened on center, evi- 

 dently a vestige of the central vitta, the meso-lateral vitt^e glossy black, 

 extending the entire length of disc ; pleurae with a dark brown mark 

 extending from below wing-base to lower margin ; center of scutellum 

 suffused with dark brown, which sometimes extends to posterior por- 

 tion of mesonotum; postnotum brown. Abdomen glossy pale green 

 at base, the apical half with black marks on dorsum which sometimes 

 consist of dorsal, lateral, and post-marginal stripes, leaving small en- 

 closed pale spotlike areas, but occasionally the segments are almost en- 

 tirely suffused with black. Legs yellow ; mid coxae brown ; mid femora 

 with a black spot on anterior side and another on posterior side near to 

 apices, which sometimes fuse, forming a ring; hind femora with a 

 black spot on the anterior surface at apical third, and the apices nar- 

 rowlv black; mid and hind tibiae black at apices, the latter most dis- 

 tinctly so; tarsal claws black. Wings clear, veins brown, the cross 

 vein, apex of radius, and a small spot immediately below the latter 

 deep black (PI. XXH, Fig. 11). Halteres yellow, sometimes brownish. 

 Eyes narrowly separated ; antenna about one half longer than head 

 and thorax combined, second joint large, globose, its dorsal surface 

 with a few short black setulae ; joints of flagellum elongated, the last 

 5 conspicuously so ; palpi short, the hairs sparse and black. Mesono- 

 tum without surface hairs, only the rows of setulce present; scutellum 

 with a group of 6 setulose hairs at apex and one or two on each side 

 near base. Abdomen slightly spatulate at apex ; hypopygium with the 

 apical portion of the lateral'arms slender, not recurved. Legs slender, 

 surfaces with short blackish hairs, which are strongest on the dorsal 

 surfaces of the mid and hind tibia? ; fore tibia with a distinct apical 

 spine, no spine on other tibiae ; basal joint of fore tarsus twice as long 

 as second and equal in length to the four apical joints combined ; basal 

 joint of middle tarsus about 2 1/3 times as long as second and dis- 

 tinctly longer than the combined length of the last 4; basal joint of 

 hind tarsus twice as long as second and but little shorter than the com- 

 bined length of the apical 4; fourth tarsal joint on all legs obcordate, 

 much shorter than fifth; fifth without ventral spines; claws subequal 

 simple, the base but slightly produced. First vein extending half the
