Description. — Black; base of third antennal joint, halteres and knees, and 
all tibiae and tarsi, including tarsal fascicle, yellow. Wings clear hyaline. 
OpacRie. Frons blackish olivaceous with orbits narrowly lighter. Face 
and cheeks whitish, sericeous. Occiput, pleura, abdomen and femora, gra}dsh 
olivaceous. Mesonotum and scutcllum olivaceous, faintly if at all vittate. 
Frons broad as long, orbits converging. Face two-thirds as broad as vertex, 
twice as long as broad; foveae weak in profile, scarcely visible above; bristles 
hair-like in series extending above middle of profile. Cheeks twice as broad as 
third antennal joint. Antennal spine minute; third joint broadly rounded 
apically; arista Avith six hairs. Mesonotal bristles strong but setulae weak. 
Scutellum flat, rounded apically. Abdomen ovate, segments subequal. Mid- 
dle femora ciliate and ciUa of their tibiae erect. Wings long; second costal 
section twice as long as third. Length. — 3.5 mm. 
Holotype . — cf ; Manahawkin, New Jersey, V, 30, 1910, (H. S. 
Harbeck), [A. N. S. P. No. 6111]. 
The type specimen was determined by Coqnillett as N. uni- 
color Lw. 
Xotiphila fulvimana new species 
This species, represented in my material by the typical pair 
alone, is rather unique and occupies a somewhat isolated posi- 
tion. It has a small extensor near the apex of the middle tibiae 
of the male, thus suggesting a relationship to the species of the 
subgenus Agrolimna. The maculation of the abdomen is char- 
acteristic, and the species, as at present known, is distinguished 
by this. The ciliation of the middle femora is weaklj' devel- 
oped and scarcely distinguishable. The systematic position of 
the species is rather difficult to determine with so little material, 
but I think it should belong here, near Agrolimna. 
Description . — cf. Black; base of third antennal joint, halteres, apices of 
femora, all tibiae and tarsi, and tarsal fascicle, black; wings taAvny or yellow, 
uniformly hyaline with yellow veins. 
Opaque; yellowish inclined to gray, or ohve-lake, not much lighter beloAv. 
Frontal vittae darker; orbits and face more yellowish. No brownish mark- 
ings except on the abdomen. These are in the form of a pair of concaved trian- 
gles on segments three to four, with their extremities attaining the apical and 
lateral margins of the segments; segment five has only a median pair of elon- 
gated spots. The median stripe well marked. Femora thinly coated with 
gray. 
Frons as broad as long, in profile convex; orbits parallel. Face nearly as 
broad as vertex, longer than broad, in profile convex; foveae and carina dis- 
tinct; parafacials narrow; bristles hair- like, four or more on lower third or 
half. Cheeks as broad as length of third antennal joint. Second antennal
