Rhamphophila lyrifera n. sp. (Figs. 52, 148, 149.) 
Differs from R. obsc Pal ce as follows: Pre-apical dark ring of 
femora considerably broader and less oblique. Ventral plate of hypopygium 
lyriform, basal part narrow, no ака projection. Median projection of 
ninth tergite longer. Main PH lobe of side-piece split to base into two 
nearly equal ers. 
SovrH Istanp: Routeburn, vl Wakatipu (G. V. Hudson, No. 17х); 
type male in the British Museum. Mount Grey, Canterbury, Novem- 
ber, 1917; one male in Dicti Museum. The wing of the type 
(fig. 52) shows some slight differences from R. obscuripennis, but these 
are not to be seen in the second specimen. 
Genus ТтхЕмүтА Hutton. 
This genus is по doubt related to Rhamphophila, from which it differs 
chiefly in its more slender build; in the muc longer rostrum ; in the 
position of Cu,,; and in the different and much simpler structure of the 
hypopygium. Only the one species is known. 
Tinemyia margaritifera Hutton. (Figs. 50, 144.) 
Tinemyia margaritifera Hutton, Trans. N.Z. Inst., p. 44, 1900. 
This species may easily be known by the remarkably elongate rostrum, 
and by wing-markings, which are strongly reminiscent of those of Epi- 
phragma. Little need be added to Hutton's description, except that front 
is very narrow, and arcular cross-vein is absent, as in the majority of New 
Zealand Limnophiline groups. The male resembles female except that 
antennae seem to be a little longer. The hypopygium is very distinctive. 
Side-pieces not lobed apically, but have large ventro-basal hairy lobes, 
and narrow transverse membranous area in middle of dorsal surface. 
Claspers are somewhat as in Ulomorpha nebulosa, the resemblance being 
particularly noticeable in the stiff bristles on inner side of inner clasper 
near tip. The parameres are long, stout, and sharp-pointed ; penis simple 
and arched.

Genus ULomorpua O.-8. 
Five species of this genus are at present known, all from North America. 
I have some hesitation in referring two New Zealand species here, because 
Alexander's Mei of en e wing of U. pilosella (the genotype) shows a well- 
marked arcular cross-v Apart from this possibly fundamental difference, 
the New Zealand бн do not exhibit any very definite character by 
which they can be separated generically. The fact that they both possess 
cell M, is of no eee pe r importance, since one of the North American 
species ' also к ` 
e two S Sid are most easily distinguished by the striking 
difference in the width of the axillary cell.
