pogonis de Meij. the larva forms a 
long linear blotch mine along the 
midrib (Spencer, 1976a: fig. 493). In 
two other species feeding on 
Hieracium , L. hieracii (Kaltenbach) 
and L. hieracivora Spencer (see 
Spencer, 1976a), the aedeagus is more 
clearly differentiated. Hering (1955) 
described L. scariolae feeding on 
Lactuca serriola in western Germany. 
This is very closely related to L. 
endiviae , but it appears to be 
distinct, as the distiphallus (of the 
holotype) is considerably larger. 
L. endiviae is clearly related to L. 
minor , known from California (see 
figs. 721, 722), but this is a darker 
species. 
New records.

empty leaf mines on Lactuca , prob. 
serriola , 25. VI. 80 (KAS), in KAS. 
Washington, Benton Co., Prosser, 23 
specimens ex Lactuca sativa ,

Liriomyza eupatoriella Spencer, 
new species 
(Figs. 646-649) 
Head. Frons 1.5-2 times width of eye, 
not projecting above eye in profile; 2 
ors, 2 ori, distance between 
ors greater than that between lower 
ors and 2 ori, which are equidistant; 
orbital setulae sparse, reclinate; 3d 
antennal segment small, round. 
Mesonotum. 3+1 strong dc, acr in 4 
rows, inner pos talar strong. 
Wing. Length 1.75 mm in both sexes, 
discal cell small, last section of 
M 3+4 3 times length of penultimate. 
Color. Head bright yellow, both vt on 
yellow ground, hindmargin of eye 
normally black beyond vte; mesonotum 
strongly shining black but narrowly 
yellow centrally adjoining scutellum 
and broadly so at hindcorners (fig. 
646); inner postalar at margin of 
black and yellow; side of thorax 
largely yellow, mesopleuron with 
narrow black bar along lower margin; 
legs with coxae and femora bright 
yellow, tibiae and tarsi brownish 
yellow, darker on hindleg; abdomen 
largely black, tergites narrowly 
yellow laterally; squama yellow, 
margin and fringe black. 
Male genitalia. Aedeagus (figs. 647, 
648) small, largely unpigmented; 
surstylus with 2 strong spines at 
inner corner. 
Host/early stages. Eupatorium 
rugosum . Larva forming long, narrow 
linear mine (fig. 649) ; puparium 
yellowish, posterior spiracles each 
with about 8 bulbs, 1 elongated. 
Holotype m. , Wisconsin, Dane Co., 
Madison, 25. IX. 76, ex leaf mine on 
Ageratina altissima (= Eupatorium 
rugosum ) coll. 12. IX. 76; paratypes 1 
f., emerged 27. IX, otherwise same 
data; 1 m. , 3 f., caught on host 
13. IX. 76; (all S. Tavormina). 
Holotype in USNM, paratypes in KAS and 
S. Tavormina collection. 
Empty leaf mines have also been seen 
from Minnesota, Minneapolis, Minnehaha 
Creek, 29. VI. 80, and Virginia, 
Arlington County, Roosevelt Island, 
1. VII. 80. 
Remarks. Although this distinctive 
species closely resembles Phytolirio- 
myza felti (fig. 990), a leaf miner on 
ferns, the male genitalia confirm that 
the two are not related. 
We are grateful to Dr. Tavormina for 
allowing us to describe this inter- 
esting species. 
Liriomyza eupatorii (Kaltenbach) 
(Figs. 788-791) 
Agromyza eupatorii Kaltenbach, 1874 
(see Hendel, 1931: 217, as Liri- 
omyza ) . Types from Europe lost. 
Liriomyza eupatorii , Frick, 1959: 404; 
Spencer, 1969a: 174; 1981: 230. 
In Europe, this species feeds most 
commonly on Eupatorium , more rarely on 
Aster and Solidago (surprisingly also
