eluded a photograph of the mine on the 
latter host. 
It is interesting to note that no 
Liriomyza is known as a feeder on 
ferns, but Phytoliriomyza species are 
known as such in the United States (P. 
clara , P. pulchella ) , in Europe ( P. 
hilarella , ?. pteridii ) , and in New 
Zealand (P. cyatheae , P. f lavopleura , 
tearohensis ) (see Spencer, 1976b). 
The arrangement of the bristles in the 
epandrium of P. fel ti closely 
resembles that found in the three New 
Zealand species and clearly indicates 
relationships among this primitive 
group of fern feeders. 
Phytoliriomyza fumicosta (Malloch), 
new combination 
(Figs. 1000-1002) 
Agromyza fumicosta Malloch, 1914b: 
310. Holotype female from Illinois 
in INHS . 
Liriomyza fumicosta, Frick, 1952a: 402; 
1959: 405. 
A male from Illinois, Champaign, 
25.V.57 (J. F. McAlpine), in CNC, was 
examined in 1967, and it was then 
noted that the species correctly 
belonged in Phytoliriomyza , with the 
aedeagus similar to that of P. dorsata 
and others in this group (which has 
been referred to as the mikii group in 
Europe). Five specimens in the CNC 
have been reexamined and the aedeagus 
and epandrium are shown in figures 
1000-1002. Although the darkening of 
the costal area may be distinct, it 
can also be almost imperceptible. The 
species may then be recognized by its 
small size and the lack of orbital 
setulae . 
The data given here of four specimens 
"ex elm leaves" may be misleading. 
This does not mean that the specimens 
were reared from elm but merely that 
they were caught on the foliage. It 
is unlikely that elm is the host. 
New records.

Phytoliriomyza pallida (Sehgal), 
new combination (new to U.S.A. ) 
(Figs. 995-996) 
Lemur imyza pallida Sehgal, 1968: 72. 
Holotype male from Alberta in CNC. 
Only the male holotype has been known, 
from Banff, Alberta. 
A single female from Montana, Madison 
County, 10 miles southeast of Eunis , 
17. VIII. 60 (D. R. Miller), in UCD, has 
now been seen that appears to represent 
P. pallida . The central yellow area 
adjoining the scutellum is slightly 
longer than indicated in the redescrip- 
tion (Spencer, 1969a: 195), but the 
specimens otherwise agree closely. 
Lemur imyza was synonymized with 
Phytoliriomyza by Tschirnhaus (1971), 
and L. pallida is therefore now 
transferred to Phytoliriomyza . 
Phytoliriomyza pulchella Spencer, 
new species 
(Figs. 1010-1012) 
Head (fig. 1010). Frons broad, twice 
width of eye, strongly projecting 
above eye in profile; normally 2 ors 
and 1 ori (this sometimes replaced by 
2 weaker ones), orbital setulae lack- 
ing; gena extended at rear, 0.33 
height of conspicuously slanting eye; 
3d antennal segment small, round, 
arista only finely pubescent. 
Mesonotum. 3+1 dc, presutural small, 
acr in 4 rows. 
Wing. Length 1.6-1.75 mm, discal cell 
relatively large, last section of 
M 3+4 only 1.5 times length of penulti- 
mate . 
Color. Head either entirely yellow or 
upper orbit darkened; mesonotum and 
scutellum uniformly matt gray; pleura 
yellow apart from large black triangle 
almost filling sternopleuron; legs 
bright yellow; squama and fringe
