Female. — Proboscis long, slender, labellse rounded, with minute outstanding 

 setae ; vestiture brownish black. Palpi short, one-sixth as long as proboscis, uni- 

 form black, with a bronzy reflection, a few outstanding setae. Antennae slender, 

 basal joints about four times as long as wide, the terminal ones increasingly 

 somewhat longer, rugose, coarsely pilose, especially on the last two joints, black ; 

 tori subspherical, with a cup-shaped apical excavation, luteous brown, darker 

 within; hairs of whorls sparse, moderate, black. Clypeus broad, rounded, 

 blackish brown, nude, with a slight pruinosity. Byes black, contiguous at the 

 vertex. Occiput smoothly clothed with flat appressed scales, black with bright 

 metallic-blue reflection, silvery in some lights, a row of erect, forked black scales 

 along posterior margin ; two coarse bristles at vertex, a row of setae along mar- 

 gins of eyes. 



Prothoracic lobes rather large, elliptical, remote dorsally, luteous, sparsely 

 clothed with small pale iridescent scales, a row of coarse setae along anterior 

 margin. Mesonotum brown, clothed with small elliptical scales, brown with a 

 submetallic-blue reflection, brighter and more greenish posteriorly; a row of 

 bristles around edges of disk; scutellum trilobate, vestiture of broad, flat 

 metallic-greenish scales, each lobe with a tuft of black bristles. Postnotum 

 elliptical, prominent, dark brown, with a tuft of small setae posteriorly. Pleurae 

 dark brown centrally, coxae luteous, clothed with patches of silvery-white scales. 



Abdomen subcylindrical, with a terminal tuft of bristles; dorsal vestiture 

 black with a blue metallic reflection ; venter yellowish silvery, the colors sepa- 

 rated on the sides in a segmentarily undulating line, the scales somewhat 

 roughened and projecting along the median line. 



Wings narrow, hyaline ; petiole of second marginal cell one-half as long as its 

 cell, that of second posterior cell nearly as long as its cell; basal cross- vein 

 slightly beyond the anterior cross- vein; outstanding scales of veins narrowly 

 elliptical, denser and broader on forks of second vein, brown with a blue reflec- 

 tion. Halteres with brown stems and black knobs. 



Legs long, slender, black with metallic-blue reflection, the femora with a 

 whitish reflection beneath; hind legs with outstanding scales on outer half of 

 tibia and flrst to third tarsal joints, especially prominent at apex of tibia, base 

 of first tarsal joint and on second joint; hind tarsi with the fourth joint, except 

 at base, and all of fifth joint white; mid tarsi with the apical half of second, and 

 all of the third and fourth joints white beneath, the last three yellowish white 

 above, submetallic. Claw formula, 0.0-0.0-0.0. 



Length : Body about 5 mm. ; wing 4.5 mm. 



Male. — Antennae with last two joints long and slender, rugose, black, with long 

 pile; the other joints shorter, about five times as long as wide, with a large whorl 

 at base and a secondary hair whorl at middle, brown, hairs of basal whorls long,
