Female. — Length, 9 mm.; wing, 6 mm., its greatest width, 1.15 mm.
Described from an alcoholic specimen.
Rostrum and palpi brown. Antennse brown, the apices of the individual
flagellar segments conspicuously pale ; terminal segments broken. Headwith the anterior vertex pale; posterior vertex and occiput dark, sending a
median dark line onto the anterior vertex.
Pronotum dark brown. Mesonotum with the pimscutum having four narrow brown stripes on the disk, the lateral margins behind the pseudosutural
fovese similarly darkened; humeral region pale yellow, the interspaces more
infuscated; scutum brownish yellow, the lobes extensively darkened; scutellum and postnotum yellowish brown. Pleura dark brown, with narrow palelongitudinal stripes, the most ventral stripe longer, beginning on the posterior face of the fore coxa, traversing the suture between the sternopleurite
and anepisternum, the dorsal portion of the meron and the ventral metapleura to the abdomen, passing immediately above the posterior coxae; asecond short pale line occupies the ventral pteropleurite, beneath the halteres; a third, slightly longer line, occupies the dorsal pteropleurite andpleurotergite, above the halteres; dorso-pleural region largely pale. Halteres relativelr elongate, pale, the base of the knobs a little darker. Legs
with the bases of the coxae abruptly infuscated, the remainder pale ; trochanters pale yellow; femora and tibiae obscure yellow, the tips a little darkened; tarsi passing into darker brown. Wings very long and narrow, asshown by the measurements, the veins and cells correspondingly elongate;
ground-color pale brownish yellow, with a restricted brown pattern, as follows: Stigma; vague seams at oiigin of Es, the anterior cord and m^cu;
less evident clouds on E 3 and E^; veins pale brown, a little darker in theinfuscated areas. Venation: Sc short, Sc-i ending opposite the origin of Es,
the latter long, strongly angTilated at origin; petiole of cell E^ elongate,approximately two-thirds Es; E^ short, straight, oblique; Ei strongly arcuated ; cell Es small ; m—cu about one and one-half times its length before thefork of M; prearcular region extensive.
Abdomen elongate, brown, the lateral margins of the segments and thepleural membrane pale. Ovipositor with the tergal valves slender, gentlyup
curved.

Male. — Length, excluding head, about 6.5 mm.; wing, 8.4 mm.
Headbroken.
Pronotum brown; lateral pretergites yellow. Mesonotal prsescutuni withthe ground-color obscure brownish yellow, with three brown stripes; medianstripe broad, reddish brown, margined laterally with darker brown; lateral
stripes darker brown, the humeral region obscure yellow; scutal lobes darkbrown, the median region in front and the posterior callus yellow; scutellum
brown, darker brown basally; postnotum reddish brown, the cephalic portion
a little darker. Pleura dark brown, scarcely variegated with paler; dorsopleural region dusky. Halteres yellow. Legs with the coxae and trochantersobscure yellow; remainder of legs broken. Wings with a brownish yellow
suffusion, the stigmal region somewhat darker; veins darker brown. Venation: Eo+s elongate, about two-thirds -K 4+5 more than one-half E.+s, inalignment with Es, the latter angulated and spurred at origin; m-cu angulated and weakly spurred; vein 2nd A ending about opposite the base ofcellM3.
Abdomen dark brown, the sternites more variegated with obscure yellowx
Male hypopygium with the ninth tergite broad and rather deeply notched,
the lateral lobes very slender, each terminating in two stout curved setae.
Basistyle stout, the ventral lobe produced into a stout fleshy lobe, unarmed
as in the subgroup. Dististyles two, the outer a little shorter, terminating
in a powerful flattened beak, with a slender, appressed lateral spine on outermargin; inner dististyle longer, appearing as a more or less sinuous slendercord, the tip acute. Aedeagus elongate, straight, subequal in length to theinnerdististyle.
