the macrotrichiz dark brown. Venation: vein 2nd A long, 
sinuiotis, ending opposite the fork of Cu. 
Abdomen dark brown. Male hypopygium with the pleural 
appendages terminal in position, consisting of an outer 
flattened blade that terminates in an acute beak, the surface 
with a short dense pubescence ; inner appendage longer than 
the outer, very slender, feebly sinuous, the tip slightly 
enlarged and with a few weak denticles; mesal face of 
pleurite grooved to receive the pleural appendages. Penis- 
enard very long and slender, straight.

NorHopHiLa, gen. nov. 
Autenne with sixteen segments ; flagellar segments elon- 
gate-oval with short verticils that are shorter than the seg- 
iments that bear them. Halteres elongate. Wings with Sc 
usually long, ending beyond the end of Rs (nebu/osa, Edwards) 
to opposite the fork of Ry,3 (fuseana, Edwards) ; Se, at the 
tip of Sc, and subequal to it ; 7 close to the tip of R, and 
on R, beyond mid-length ; Ry,; as long as, or longer than, 
the basal deflection of Cu,; cell M, present; anterior 
arculus atrophied. Abundant macrotrichiv in all the cells 
distad of the cord, as well as in the centres of cells C, 
Is¢ R,, and R, and the distal ends of cells M, Cu, and 1st A. 
Valves of the ovipositor moderately elongate, the slender 
tergal valves geutly upcurved. 
Genotype :—Ulomurpha fuscana, Wdwards (New Zealand). 
The two New Zealand species that Edwards has referred 
to Ulomorpha are not congeneric with the five Nearctic 
species of the genus. Ulomorpha has vein Sc shorter, Sc, 
ending before the fork of Rs; 7 far removed from the tip of 
R,, on Ry before mid-length ; cell Ay sessile or very short- 
petiolate; cell M4, present or (usually) absent; arculus 
complete. Verticils of the flagellum elongate as in Pé/aria. 
The relation of Nothophila to other generalized Hexatomine 
eenera in New Zealand is apparently analogous to that of 
Ulomorpha to Pilaria, Sintenis.
