1944] New Neotropical Phoridoe 155 
but distinctly wider than high; four postantennal bristles, the 
lower pair not much shorter than the upper; antial bristles close 
to the lowest laterals, scarcely below them but much farther 
from the eye-margin; lower transverse row of four equidistant 
bristles slight bowed downwards medially; ocellar row as usual, 
large like the other frontal bristles. Ocellar tubercle and median 
frontal line well defined, the surface of the front sub-shining, 
distinctly white pollinose. Postocular cilia stout, of moderate 
length; cheek just below the eye with two stout downwardly 
directed bristles; three above these toward the antennae small 
and delicate. Palpi small, flat, with moderately long bristles 
below toward apex. Third antennal joint large, but not notice- 
ably swollen, rounded, the arista one-half longer than the front, 
with short pubescence. Proboscis very short, stout, bluntly 
pointed at its tip. Mesonotum shining, with fine pubescence. 
One pair of dorsocentral bristles set very close to the scutellar 
suture. Scutellum narrow, triangular, with two bristles. Pleurae 
shining, but noticeably pollinose above, entirely without hairs 
or bristles, except two small bristles at the lower anterior corner 
of the propleura. Abdomen dull black, segments of approxi- 
mately equal length, with a few weak, bristly hairs at the sides 
and a marginal row on the posterior margin of the sixth tergite. 
Hypopygium simple, cylindrical, appearing quadrate or some- 
what tapering posteriorly in lateral view. Legs slender, includ- 
ing the hind femora which are three times as long as broad. 
Front tarsi slender. Middle tibiae with the dorsal black line 
distinct at apex, with about eight weak setulae just inside the 
dorsal line. Posterior femora slender, exactly three times as 
long as their greatest length. Dorsal hair-line of hind tibiae 
complete, straight except for a slight angulation very near to 
the base; with a single posterio-dorsal series of eight bristles, 
each about the width of the tibia. All tarsi very slender. Wings 
narrow, costa less than half the wing-length (70:31); its bris- 
tles delicate, moderately long and rather closely placed; first 
section of costa as long as the other two sections together; 
second section three times the length of the third (28:21:7). 
Third vein absolutely straight except beyond the very narrow 
cell formed by the very oblique second vein; fourth vein strongly 
curved at base, but nearly straight beyond; fifth vein curved 
near base, very slightly sinuous beyond; sixth sinuous; seventh 
practically straight.
